P1345 Chevy: Crankshaft position- camshaft position correlation

Vehicle owners who are not mechanics have a major problem in common – the difficulty of getting rid of certain DTCs. The P1345 code is definitely one of these Diagnostic Trouble Codes.

Worry not. This article will dive deep into the P1345 code on GM (Chevrolet) vehicles. We will tackle an older Chevy engine model, specifically the 5.7 Vortec, in which this problem is highly prominent.

However, this knowledge is transferable and will help you fix your Chevy. There will be a few differences depending on the engine design and the types of ignition triggers. At the very end, you will be able to fix the problem yourself, if you are a little bit handy.

This article will dive deep into the P1345 code on GM (Chevrolet) vehicles.

P1345 Chevy definition and meaning

Definition

Trouble code P1345 is a manufacturer-specific code defined as Crankshaft position-camshaft position correlation on General Motors vehicles.

Meaning

P1345 is a manufacturer-specific DTC, which means that diagnosing it will be different for different manufacturers. Moreover, the code may only apply to specific vehicles: Audi, Isuzu, Toyota, BMW, GM (Chevrolet and GMC), Lexus, Mazda, and Volkswagen. The P1345 code on a Chevy or GMC truck will defer from the same code in another car model.

Regardless of the definitions, these codes have one thing in common – they indicate an ignition problem. As earlier stated, these codes defer due to the type of engine and ignition triggers used in each specific vehicle. However, they have another thing in common: the application of Camshaft Position Sensors (CMS) and Crankshaft Position Sensors (CKS).

The camshaft position sensor is a sensor in your vehicle. It provides the Engine Control Module (ECM) or Powertrain control module (PCM) as referred to in some vehicles, with the exact position of the camshaft lobes relative to the valve openings on each cylinder. This information will then be used by the Engine control module (ECM) to choose the best fuel injector timing.

On the other hand, there is the crankshaft position sensor (CKS), which is a sensor that provides a signal to the engine control module indicating the position of the crankshaft or crankshaft timing relative to the top dead center on the compression stroke of the cylinder number 1 in the engine.

These two sensors work together with the engine control module to control engine timing. These sensors will be in sync if everything is working properly. When the interrelation between the camshaft position sensor and crankshaft position sensors is out of sync for more than 1 or 2 degrees, the error code P1345 will be recorded.

The P1345 Chevy code may be caused by faulty CKS and CMS sensors, but in most cases, it results from a problem in engine timing. This confusion is done away with in newer vehicles whose engines adjust the timing themselves. In these newer vehicles, you will also receive a p0335 code and p0340, telling you that the CKS and CMS sensors are bad or malfunctioning.

List of OBD2 codes that relate to P1345 on Chevy

1. P0335 – Crankshaft Position Sensor ‘A’ Circuit malfunction

2. P0340 – Camshaft Position Sensor ‘A’ Circuit malfunction

Symptoms of P1345 on Chevy?

1. Check engine light ‘ON’ – like other codes, this code will trigger the ‘check engine’ light and get stored in the vehicle’s memory system.

2. Engine misfires above 1500 rpm – an engine may misfire if there is a problem with the distributor, resulting in the lack of enough current to ignite the spark plugs. The resulting trouble is a misfire. At higher speeds, the ECM usually tries to adjust valve lift. Therefore, engine misfiring may be an indication of your valve timing being off.

3. Rough idling and stalling while driving – most engine problems such as these will deem your engine performance inefficient, resulting in the engine idling and stalling.

4. Difficulty in starting the engine – an engine with poor timing will exhibit difficulties in starting up since the engine timing is crucial for its operation. Newer vehicles improved on this by having the engine time itself.

Causes of P1345 on Chevy?

1. Loose, faulty, or bad camshaft position sensors and crankshaft position sensors (highly unlikely)

The CKS and CMS may be faulty if the p0335 code and/or p0340 codes are recorded too. A quick fix for this would be to replace the sensors or have a mechanic fix them. However, in the absence of these two codes, the problem will be located elsewhere.

2. Stretched, slipped, or improperly installed valve timing chain

There may be an excessive free play on the valve timing chain and gear assembly that may result in the valve timing being off. This may be due to mechanical wear or improper installation.

3. Incorrect distributor positioning or loose distributor rotor on the distributor shaft (most likely)

The distributor transfers current to the ignition coils for firing up the spark plugs. If it fails, it will not deliver current at the right time to the appropriate coil resulting in misfires and engine timing going off.

4. Bad wiring connections causing simple electrical connection failures

Chafing, corroding, rubbing, or burning spots on melted wire insulation may result in connection problems. These types of wiring problems should be checked as a regular maintenance procedure.

How serious is the P1345 Chevy OBD2 code?

As much as you may get by without fixing this trouble code for a while, it is advisable not to. The engine will have trouble starting on multiple occasions, and it may also suddenly stop. These two scenarios are not any driver’s cup of tea. Moreover, the check engine light may end up staying on till you fix the problem.

How to diagnose and fix the code P1345 on Chevy?

Tools needed

Method

We are specifically tackling a 5.7 Vortec engine here. You will need to check if there are any technical service bulletins (TBS) for your vehicle. This may save you time and money if the manufacturer has put out a fix for this specific problem.

1. You will first need an OBD scan tool to connect to the OBD port on your car. Use it to scan for all the stored codes to ensure you diagnose those other codes before the P1345.

2. Check for any corroded, burnt, or defective wiring in the connections around the CKS and CMS sensors. Pull the connectors apart and inspect the terminals inside. If they are corroded or burnt, you will have to clean them with an electrical cleaner and the brush listed above.

Let them dry. Apply dielectric silicone grease on the terminals before returning the sensors.

3. Check for any damages and faults on and around the CKS and CMS sensors. If any, you will need to replace them and see if the problem is solved. To see if the sensors are working correctly, you will need to use a Digital Volt Ohm Meter (DVOM). Test the 5V power supply circuit going to each sensor to ensure it is being powered up.

4. Clear the trouble codes from memory and see if the P1345 code returns. If it does, then the problem is elsewhere. Proceed to the next step.

5. Analyze the assembly of the timing chain and gear assembly to make sure there is no excessive free play. Fix the problem by adjusting the installation. You may also need to get spare parts for the affected components. If this does not fix the problem, then the last and final diagnosis will be a problem with the distributor.

A distributor may be loose or missing. It is responsible for current delivery to ignition coils in the correct firing order and correct time period. It contains a rotor, which may be loose in this case. On top of this, the gear inside of the distributor may be bad.

The distributor may need to be replaced, but if it is new and/or in good working condition, its positioning is probably off.

6. Using the scan tool, connect it to the OBD port on your vehicle with ignition OFF. Start the engine. From the scan tool, read the “Cam Retard Offset,” you will need to get your engine to 1000 rpm for accurate results.

7. A reading of +/-2 degrees of Zero is an indication of optimal timing. Otherwise, you will need to adjust the distributor. You can adjust it by loosening the bolt on the distributor while the engine is off. Connect scan tool and monitor the “Cam Retard Offset” reading. Start the engine and make sure it reaches 1000 rpm.

8. Adjust the positioning by turning the distributor clockwise if the reading is positive and anticlockwise if the reading is negative. Do this till the “Cam Retard Offset” reading is within +/- 2 degrees of Zero, finally solving the issue.

Tips to avoid P1345 in the Future

1. Perform regular preventive maintenance. Problems related to P1345 will be caught earlier.

2. Avoid driving through deep puddles because water will get into the distributor cap and short out.

P0120 Code: Understanding TPS “A” Circuit Malfunction

If you’ve ever encountered the P0120 OBD-II trouble code, you know how frustrating it can be to have your vehicle’s check engine light illuminate. This code refers to the “Throttle/Pedal Position Sensor/Switch “A” Circuit” issue, which can cause several serious issues if not addressed.

In this article, we’ll take a comprehensive look at the P0120 code, including its severity, common symptoms, underlying causes, and the necessary diagnostic and repair steps. By understanding this information, you’ll be able to address the issue quickly and efficiently, getting your vehicle back on the road in no time.

So, let’s dive in.

P0120 Code: An Overview

Here is a summary of the P0120 code. Check it out!

Definition: Throttle/Pedal Position Sensor/Switch “A” Circuit
Severity: Medium
DIY Skill Level: Intermediate
Continue To Drive?: Yes (short-term)
Estimated Repair Cost: $50 – $200

What Does The P0120 Code Mean?

P0120 is a diagnostic trouble code (DTC) that indicates there is a problem with the throttle position sensor (TPS) circuit, specifically circuit “A.”. While it is a generic code that can occur in various car makes and models, it is particularly more common in Chevrolet, Toyota, and Nissan among others.

The TPS is part of the engine management system, which controls the air-fuel mixture and other engine parameters to optimize performance and emissions. The TPS works together with the throttle valve and the Engine Control Unit (ECU) to ensure that the engine receives the correct amount of air.

When you press the accelerator pedal, the throttle valve opens, allowing more air to enter the engine. The TPS sends a signal to the ECU indicating the position of the throttle valve. The ECU then uses this information to calculate the correct amount of fuel to inject into the engine.

If the TPS “A” circuit is faulty, the TPS may not be able to send a signal to the ECU, or the ECU may not be able to receive the signal, triggering the code P0120. Specifically, when the ECM identifies that the voltage output from TPS circuit “A” exceeds the designated voltage range, in contrast to TPS sensor circuit “B,” the P0120 code is triggered. The specific voltage range may differ depending on the vehicle’s manufacturer and model.

Note: In some vehicle models, the ECU monitors the TPS and the manifold absolute pressure (MAP) sensor together. The ECU expects a consistent relationship between the throttle position and the manifold pressure. If there is a significant difference between the two, it can trigger the P0120 code.

How Severe Is P0120?

The P0120 code is of medium severity. While it doesn’t indicate an immediate danger or major mechanical failure, it should be addressed promptly to prevent potential issues from getting worse.

P0420: Catalyst System Efficiency Below Threshold (Bank 1)

Did your car scanner throw the P0420 code? Are you confused about which decision to make and whether to keep driving?

Continue reading to briefly evaluate your current situation.

P0420 Definition: Catalyst System Efficiency Below Threshold (Bank 1).
Code Type: Generic – P0420 indicates the same problem whether you’re having a Chevy, Honda, or Nissan, etc.
Can I drive with the P0420 code? Yes, but doing so will further damage your catalytic converter.
Easy to fix? Intermediate to advanced level.
Cost: $400 – $2200 (common).

Now you know that the P0420 code may not imply immediate danger.

To avoid wasting time and money on finding the problem, let’s dive into four causes of the P0420 code and their corresponding solutions.

What Does the P0420 Code Mean?

The P0420 is the diagnostic code for a defective or underperforming catalytic converter. However, this code may pop up due to other reasons not directly related to the converter.

What Is The Catalytic Converter’s Function?

To protect the environment, the catalytic converter limits and breaks down the harmful exhaust gasses (e.g., Carbon Monoxide and Nitrogen Oxide) from internal combustion engines.

How Do You Know Your Catalyst System Is Below Efficiency?

There are two oxygen sensors sitting near the converter, one at the front (upstream) and another at the rear (downstream).

The upstream sensor measures the O2 level of exhaust fumes exiting the engine. Meanwhile, the downstream sensor checks the O2 level of gasses leaving the converter.

In normal conditions, the data from the upstream sensor will fluctuate while the downstream’s must remain steady. If both sensors output the same data, the catalyst system is inefficient, harmful gasses will be released into the environment, and P0420 is set.

When the values of both sensors are similar, the PCM infers a low efficiency in the catalyst system.

The P0420 code may not seem serious enough to stop driving. However, the catalyst system may be further damaged, and the car will fail emission tests.

P0420 Causes Identification: Quick View

A faulty catalytic converter is often the culprit when a scanner indicates the P0420 code. However, the downstream oxygen sensor or a failing engine component may be the root cause. Hence, another code may show up with the P0420.

Below are the likely causes of this code and their possible solutions.

Codes Combination	Causes	Solutions
Only P0420	Faulty catalytic converter (most common)	Replace the catalytic converter
P0420 + P0136/P0137/P0138/P0139/P0140	Faulty downstream oxygen sensor (Bank 1)	Replace downstream oxygen sensor (Bank 1)
P0420 + Weird exhaust noise	Exhaust leak near downstream O2 sensor (Bank 1)	Use epoxy putty (small leak) or weld (large leak)
P0420 + P0301/P0303/P0305/P0307	Leaky fuel injectors	Replace fuel injectors

Note: The causes for each code combination are the most common ones. There can be some uncommon issues hidden under those codes.

P0420: Causes, Symptoms, And How to Fix

If a vehicle outputs the P0420 diagnostic code after scanning, the following might be the cause.

Cause #1: Faulty Catalytic Converter

A faulty catalytic converter is the most common cause of the P0420 code. Sometimes, this might be due to:

Structural damage caused by thermal shocks
Weak welding points
Direct hits from rocks and debris
Unburnt fuel coats the catalyst

In any case, a faulty catalytic converter fails to convert exhaust fumes to environmental-friendly gasses.

Therefore, the exhaust fumes exit from the catalytic converter without any changes (filtering or cleaning). As a result, the upstream and downstream oxygen sensors’ reading will be the same, triggering P0420.

Look out for the following symptoms to identify a fault catalytic converter.

Check engine light
Dark exhaust smoke
Gasoline smell around the car
Excess heat under the car
Poor engine performance

The chances of restoring the catalytic converter to its initial condition are slim. A suitable replacement is the best solution though it is pricey.

Watch this 3-minute video from Scotty Kilmer to know the detailed steps on how to replace the catalytic converter.

Cause #2: Faulty Downstream Oxygen Sensor

The downstream oxygen sensor’s function is to keep track of the catalytic converter’s efficiency. If the sensor fails, it may tell the PCM that the catalytic converter is underperforming (in fact, it isn’t.)

There are no obvious symptoms of a faulty downstream oxygen sensor. You can conduct an O2 sensor test to determine whether it is faulty or not.

If it is your problem, your scan tool will trigger only P0420 or with other codes like P0136, P0137, P0138, P0139, and P0140.

The most realistic solution is to replace the oxygen sensor. Buying the part and changing it yourself will save you money from the repair shop.

You can watch this video from 1A Auto and replace the downstream oxygen sensor yourself to save money.

Cause #3: Exhaust Leak Near Downstream O2 Sensor

The exhaust leak affecting the output voltage can be found near the downstream oxygen sensor.

The exhaust system can suck oxygen into the exhaust flow through a leak due to the pressure differences. Consequently, the sensors will capture incorrect readings due to the extra oxygen, causing the PCM to set P0420.

The following are the common symptoms of an exhaust leak:

Unusual blowing noise from underneath the car
Low engine performance
Unpleasant odor around the car during operation

In the case of small leaks, epoxy glue will resolve the issue. However, some larger leaks may require welding.

If you are DIYers, check this video from Charles Coushaine to learn the process of sealing the exhaust leak.

Cause #4: Leaky Fuel Injectors

Leaky fuel injectors can also be the root cause of the P0420 code. When the fuel injector leaks, excess fuel in liquid form reaches the combustion chamber.

As a result, some amount of fuel is left unburnt and passed to the exhaust system. Over time, the waste fuel builds up and overloads the catalyst system, reducing its efficiency drastically.

The following symptoms can mean that a car has leaky fuel injectors.

Gasoline smell in and around the car
Rough engine performance and idling
Increased fuel consumption
Heavy exhaust fumes
Excessive heat under the car

The only way to resolve the problem is to replace the leaky fuel injectors with suitable ones.

How Much Does It Cost to Fix P0420?

The cost of resolving the P0420 depends on the root cause of the problem. A fault catalytic converter is the most common cause which costs $400 – $2,000 to repair yourself. If it is too difficult to handle this job, you will pay $500 – $2200 to visit a mechanic.

The following are the possible costs of fixing the P0420.

The Estimated Repair Cost Of P0420

Solutions	Cost
Replace the catalytic converter	DIY: $400 – $2000 Repair shop: $500 – $2200
Replace downstream oxygen sensor (Bank 1)	DIY: $20 – $95 Repair shop: $100 – $450

P0101 – Mass or Volume Air Flow “A” Circuit Range/Performance

The P0101 OBD2 code indicates a problem with your mass air flow circuit. Proper air flow is key to your engine’s operation, and the MAF sensor helps to regulate it. When it has a problem, it can make your system run rough and reduce your gas mileage.

There are a couple of primary sources of the P0101 trouble code. It could mean there’s a vacuum leak somewhere in your exhaust system. It could also indicate a problem with the MAF sensor itself. The good news is, it’s relatively easy to find the source of the code if you follow the diagnostic process outlined below.

P0101 Code Definition

P0101 Code Definition (Generic): Mass air flow (MAF) circuit range/performance

P0101 Audi Code Definition: Mass or volume air flow circuit range/performance problem

P0101 Duramax Code Definition: MAF/VAF sensor range/performance problem

P0101 Mercedes Code Definition: Mass or volume air flow circuit range/performance problem

P0101 Nissan Code Definition: Mass Air Flow (MAF) (very common, service bulletin exists)

P0101 Toyota Code Definition: Mass air flow circuit range/performance

P0101 VW Code Definition: Mass or volume air flow circuit range/performance problem

If you want to learn about the P0101 OBD2 code, this is the right place

What Does P0101 Mean?

The P0101 OBD2 code tells you the amount of air entering the engine is out of your engine’s specified range. The air flow into the engine is measured by the mass air flow (MAF) sensor. It sends this information to the engine control unit (ECU) to help manage the engine.

When the air flow reported by the MAF sensor is outside your system’s acceptable range, the P0101 trouble code activates. Issues with the air flow also reduce your engine’s performance and can make your car drive erratically.

The MAF sensor is mounted in the engine air intake tract for your vehicle, downstream from your air filter. It measures the air’s density and volume being pulled into the engine by sampling a portion of the air. From this data, it extrapolates the conditions in the total air mass. Some MAF sensors also have an air temperature circuit, which could also contribute to the air flow problems.

Many systems can be the root cause of this trouble code. Your system could have a vacuum leak or other mechanical issue that allows too much air into the engine. It could also be a malfunction of the sensor itself. A full diagnosis is the best way to track down and fix the problem.

What Are The Symptoms Of The P0101 Code?

You will likely notice drivability problems if there is too much air going into your engine. These symptoms include:

Illumination of the check engine light
Stalling engine
Black smoke in the exhaust
Rough starts or idling
Low engine power
Decreased fuel economy

What Are The Causes Of P0101?

MAF sensor is dirty or faulty
Damaged or faulty wires on the MAF sensor
Damaged air intake boot
Clogged air filter
Leaks in the air intake system
Clogged catalytic converter (most common on Chevrolets and GMCs)

How Serious Is The P0101 Code?

The P0101 code is moderately severe. While it’s not dangerous to drive your car with this code active, sustained driving can damage the engine. You should repair this trouble code as soon as possible.

How To Diagnose The P0101 Code

The OBD2 scan tool can diagnose the P0101 code

You may find technical service bulletins for this trouble code related to your vehicle’s make or model. Check before you start your diagnosis, as this can save you some time in isolating the problem.

Tools You’ll Need:

Method:

Scan your system for other related trouble codes, especially P0100-P0104, which indicate other issues with the air flow. If these codes are present, diagnose them first.
Read the real-time data for the oxygen sensors and MAF sensor to check their operation.
Open the air intake box and check the air filter. Make sure it’s installed properly, and replace it if it’s clogged or dirty.
Remove the air intake snorkel. Check it for damage, and inspect the MAF sensor. While you’re at it, check the wiring around the harness for damage or loose connections. Replace the air intake snorkel if necessary.
Check the air intake system for leaks. You can visually inspect the hoses, running your fingers down them to check for hidden weak spots and cracks. Also, make sure they’re securely attached.
Run an exhaust back pressure test to check for clogs in the catalytic converter. Clean it using a catalytic converter cleaner, following the instructions on the bottle.

Common Mistakes To Avoid While Diagnosing The P0101 Code

While the MAF sensor can cause the P0101 trouble code, it’s not always the problem. Make sure you check for clogs and leaks throughout your system before you replace the sensor.

What Should You Do To Fix The Code P0101?

The steps you take to diagnose P0101 may clear it, as well. Clear the codes and take a test drive. If the code comes back, follow the steps below:

Replace any damaged wires or leaking hoses found in your diagnosis.
Clean your MAF sensor. This sensor is very sensitive, so only use cleaners specifically designed for mass air flow sensors. Spray each side of the sensor for 3-5 seconds, wait 10 seconds, then spray again. You don’t need to wipe it off.
Clear the codes and test drive your car to see if the code comes back. If it does, replace the MAF sensor. Make sure you use an OEM component, not an after-market product. Incompatible MAF sensors can lead to further problems with your system.
If there is mesh in your air intake system (mostly Volkswagen vehicles), inspect it for dirt and damage. Clean or replace it as necessary.
Check the operation of the catalytic converter. If it’s still failing after cleaning it, replace it.

How to clean or replace MAF sensor

Tips To Avoid P0101 In The Future

Dirt and build-up in your engine can cause many problems, and the P0101 trouble code is among them. Check your air filter regularly, and make sure it’s correctly installed when you replace it. Regular maintenance of your engine’s fluids, especially the oil, will also help keep your engine clean.

Frayed wires can also trigger this code. Make sure all the wires in your system are kept clear of ignition coils and other potential sources of damage.

P0118: Engine Coolant Temperature Sensor Circuit High Input

Suppose you are driving down the road, and your check engine light turns on, displaying a P0118 code error!

Well, you read that using an OBD scanner, but what next?

Let’s discuss your situation in this article.

P0118 Definition: Engine coolant temperature sensor circuit high input problem.
Code type: Generic – P0118 indicates the same problem whether you’re having a Chevy, Honda, Dodge, etc.
Can I drive with the P0118 code? Yes, you can. However, it may cause damage to your engine in the long term.
It is easy to fix? DIY to advanced levels.
Cost: $85 – $170 (common).

To help you understand the P0118 code, I have split this article into four parts: causes, symptoms, how to diagnose, and how to fix the P0118 code.

Read further and unveil everything you need to know about the P0118 and its quick fixes.

What Does the P0118 Code Mean?

The P0118 code stands for “Engine Coolant Temperature (ECT) Sensor Circuit High Input”. The code is triggered when PCM recognizes that the input voltage of the ECT is more than 5V.

The ECT sensor measures the engine coolant temperature. This data is sent to the powertrain control module (PCM) to control the cooling system.

Under good conditions, the higher the temperature, the lower the ECT sensor voltage. This number ranges from 0.5 to 4.5V.

The proper range of ECT sensor voltage is from 0.5 to 4.5V.

As mentioned above, the code P0118 is set when the ECT voltage is higher than 5V. This means the PCM is receiving a “too cold” signal (-40F). Of course, the PCM knows this signal is abnormal and does not believe in it (if it did, the thermostat would close, leading to an overheating engine.)

As a result, P0118 makes your car enter failsafe mode to prevent the engine from overheating.

In this mode, the cooling system is allowed to run at maximum capacity, which includes:

Radiator constantly running.
Wide-open thermostat.
AC off.

Consequently, the car takes more time to warm up. This reduces fuel economy and damages the engine parts in the long run.

Other codes may appear with P0118: P0115, P0116, P0117, and P0119.

P0118: Causes, Symptoms, and How To Fix

Causes #1: ECT Wiring/Connector Problems

In many cases, P0118 is caused by the ECT sensor connection problems in the wiring harness or inside the connectors.

The symptoms of this problem are shown by:

Erratic temperature gauge readings.
Malfunctioning air conditioner.
Radiator fans running constantly.
High fuel consumption.
Hard start.
Check engine light on.
Black smoke from the engine.
Poor idling.

If this is the case, repairing the wiring harness will fix the problem.

Causes #2: Open ECT Sensor’s Circuit

If the wiring is fine, the circuit inside the ECT sensor can be open for various reasons, which leads to the P0118 popping up.

The symptoms of a bad ECT sensor are the same as the ECT wiring/connector causes.

In this case, replacing the ECT will fix the P0118.

Causes #3: Faulty PCM (Rare)

The powertrain control module (PCM) is the main engine computer that ensures your engine transmission works effectively. So, a faulty PCM can be a potential cause of the P0118 code, although it rarely occurs.

Also, there are combination codes with P0115 and P0117 associated with faulty PCM in some cases.

You can repair faulty PCM by reprogramming it, although that won’t be effective in the long run.

So, replacing the PCM would be the best option.

P0118 Causes Identification: How to Diagnose

As mentioned above, in most cases, there are 2 main causes triggering the P0118 code:

The ECT wiring harness.
The ECT sensor itself.

The question is: “Which one?”

Continue reading to reveal how you can diagnose the cause of the P0118 code.

Diagnosing ECT Wiring/Connector Problems

First, locate the sensor and visually inspect its wiring to check if there are any burnt, broken, or unplugged wires and fix them.

If there isn’t, use a multimeter to check the wiring harness. Here are the steps to do so:

Unplug the cables connecting the sensor.
Turn on your vehicle’s ignition key without starting the engine.
Connect the multimeter red clip to the positive terminal and the black clip to the ground wire.
Record the multimeter readings. Your sensor wiring has a problem if your multimeter registers a zero ohm reading. Slightly more than zero ohms multimeter reading should be good wiring.

Diagnosing Open ECT Sensor’s Circuit

If all the wires are good, the ECT itself is very likely to be the problem.

Here’s how you can test it:

Locate the ECT sensor: near the thermostat in the cylinder head or block or on the thermostat housing.
Remove the sensor wiring connectors while the engine ignition is off.
Connect an ohmmeter between the sensor terminals. Measure and record the resistance.

If the ohms reading is more than 6600Ω or infinity, the sensor’s circuit is open and needs a replacement.

Diagnosing Faulty PCM

After testing the ECT sensor and circuit problems and there aren’t any problems with these, a bad PCM should be the last conclusion.

However, this is a rare cause.

Having a mechanic handle it is the best solution in this case. And it’s not cheap!

How Much Does It Cost to Fix the Code P0118?

Most P0118 causes can be fixed by yourself with a few bucks.

For example, the ECT sensor can cost you $10 to $30.

Most Auto shops charge the cost of fixing code P0118 in terms of the hours for the work.

Although the charges vary from shop to shop, you can expect to spend between $85 and $170, excluding the cost of the parts.

The estimated repair cost of the P0118

Solutions	Repair cost
Repairing ECT wiring / connector problems	DIY: a few bucks Mechanic: $85 to $170
Replacing malfunctioning ECT sensor	DIY: $10 to $30 Mechanic: $85 to $170
Replacing faulty PCM	DIY: Not recommended Mechanic: $1000 to $3000

Note: The data in this table is dated June 2022. The exact cost will depend on various factors such as mechanic rates, car model, etc.

P0430: Catalyst System Efficiency Below Threshold (Bank 2)

Have you just scanned your vehicle and captured the P0430 code? Do you want to know what it means?

Well, you are in the right place because we have you covered.

P0430 Definition: Catalyst System Efficiency Below Threshold (Bank 2)
Code Type: Generic – P0430 indicates the same problem whether you’re having a Ford, Chevy, or Nissan, etc.
Can I drive with the P0430 code? Yes. The P0430 is not an immediate threat.
Easy to fix? Intermediate to Advanced level.
Cost: $500 – $2,200 (common)

This code does not cause a prompt danger.

But to avoid more future expenses, let’s dive into 4 causes that might trigger the P0430 code and how to fix them!

What Does The P0430 Code Mean?

P0430 is a diagnostic trouble code triggering when the catalytic converter underperforms.

A catalytic converter breaks harmful pollutants in the exhaust gas into safer forms. If the catalytic converter fails, more oxygen is present in the exhaust gas downstream.

The downstream oxygen sensor detects that change and sends the signal to the powertrain control module (PCM). The PCM, in turn, sets the P0430 code and the Check Engine Light comes on.

This is a moderate fault, but it is crucial to diagnose the car and fix it as soon as possible.

P0430 Causes Identification: Quick View

A problem with your vehicle’s catalytic converter may sometimes trigger more than the P0430 code. An OBD2 scanner may return other DTCs depending on what causes the issue.

The chart below summarizes all possible combinations.

Codes Combination	Causes	Solutions
Only P0430	Faulty catalytic converter (most common) Exhaust leak near downstream O2 sensor (Bank 2) Leaky fuel injectors	Replace the catalytic converter Use epoxy putty (small leak) or weld (large leak) Replace fuel injectors
P0430 + P0156/P0157/P0158/P0159/P0160	Faulty downstream oxygen sensor (Bank 2)	Replace downstream oxygen sensor (Bank 2)

Note: The causes for each code combination are the most common ones. There can be some uncommon issues hidden under those codes.

P0430: Causes, Symptoms, And How To Fix

Many reasons why your vehicle sets the P0430 code exists. That can vary from model to model, but the following are the most common ones:

Cause #1: Faulty Catalytic Converter

A catalytic converter is designed to last the lifetime of the vehicle. However, it can also become faulty.

In that case, its function will be compromised. This malfunction is detected by the downstream oxygen sensor, which signals PCM to activate the P0430 code.

The most common symptoms of a bad catalytic converter include the following:

Rotten egg smell
Rattling noise underneath the car
Decreased gas mileage
Engine misfiring
Failed emission test
Check engine light on

A faulty catalytic converter requires replacement. You can do this yourself, but this process is a little advanced and expensive. But, of course, bringing it to mechanics is even more pricey.

Watch this 3-minute video from Scotty Kilmer to know the detailed steps on how to replace the catalytic converter.

Cause #2: Faulty Downstream Oxygen Sensor

A downstream oxygen sensor keeps track of the catalytic converter’s performance.

Its failure will trick the PCM into thinking the catalytic converter is bad, triggering the P0430.

If this is your problem, you may receive other DTCs along with P0430, such as P0156, P0157, P0158, P0159, and P0160.

Downstream O2 sensors do not take part in the air-fuel ratio adjustment process. As a result, there is almost no symptom in this case but the CEL.

The most realistic solution is to replace the faulty downstream O2 sensor. Fortunately, it isn’t expensive or difficult to install without the help of a mechanic.

You can watch this video from 1A Auto and replace the downstream oxygen sensor yourself to save money

Cause #3: Exhaust Leak Near Downstream O2 sensor

A leaking exhaust near the downstream O2 sensor will let the air go into the pipe. This air confuses the sensor’s reading, which makes the PCM activate the P0430 code as a warning sign.

Look around the downstream O2 sensor area to identify the leak. It can likely be the problem causing a false reading.

An exhaust leak can cause the following:

Check engine light on
Blowing sound from underneath your car
Louder engine sound than usual
Low engine performance
Decreased fuel efficiency
Unusual odor in the cabin

Use a smoke test to identify the leak.

After confirming the location, you can repair it using the epoxy putty or welding the leak. It can be a difficult task for anyone unfamiliar with DIY jobs.

If you are DIYers, check this video from Charles Coushaine to learn the process of sealing the exhaust leak

Cause #4: Leaky Fuel Injectors

Leaky fuel injectors will allow more fuel into the combustion cylinder. That disrupts the usual cycle since not all the gas gets burned. The excess finds its way into the exhaust system, where they burn and produce soot that blocks the catalytic converter.

This can also result in high temperatures that literally melt the catalytic converter inside.

Signs of leaky fuel injectors include the following:

Fuel consumption increases
Poor and shaky idling
Gasoline smell
Hard starts (when the engine is hot)
Bad emission performance

The solution to leaking fuel injectors is replacing them. This is not an easy job, so it is recommended to visit a mechanic.

How Much Does It Cost To Fix P0430?

The cost of fixing P0430 varies significantly depending on the affected part, model, and year of the car.

Catalytic converters are the most common culprits, which cost about $500 – $2,200 to fix at an auto repair shop. You can save on the labor fee through a DIY approach. In that case, you will need $400 – $2000.

The Estimated Repair Cost Of P0430

Solutions	Cost
Replace the catalytic converter	DIY: $400 – $2,000 Repair shop: $500 – $2,200
Replace downstream oxygen sensor (Bank 2)	DIY: $20 – $200 Repair shop: $60 – $300
Use epoxy putty (small leak)	DIY: under $10 Repair shop: not recommended
Weld the leak (large leak)	DIY: not recommended Repair shop: $30 – $100
Replace fuel injectors	DIY: $400 – $900 Repair shop: $600 – $1,200

Note: The data in this table was collected in June 2022. The actual price depends on many factors, such as your car’s make and year, mechanic’s rate, etc.

You Ask, I Answer

P0018 Code: Crankshaft Position – Camshaft Position Correlation (Bank 2 Sensor A)

If you’ve encountered the P0018 code during a scan of your vehicle’s onboard diagnostic system, fret not! We’re here to discuss its meaning and implications.

So, what does the code P0018 mean? In simple terms, it points to a potential issue with the correlation between the crankshaft position and the camshaft position on Bank 2 Sensor A. Dive in to learn more about this issue as we’ve got you covered with an in-depth exploration of its causes, symptoms, diagnosis, and repair methods.

P0018 Code: An Overview

Check the key information of the P0018 code below!

Definition: Crankshaft Position – Camshaft Position Correlation (Bank 2 Sensor A)
Severity: High
DIY Skill Level: Intermediate
Continue To Drive?: No
Estimated Repair Cost: $50 – $500

What Does The P0018 Code Mean?

P0018 is an OBD-II generic code indicating a lack of correlation between the signals from the camshaft position (CMP) sensor A for bank 2 and the crankshaft position sensor (CKP). This code is commonly triggered in various car brands such as Ford, Subaru, Chevrolet, Hyundai, Kia, GMC, Mercedes, Toyota, Subaru, Jeep, Audi, and Lexus.

In a typical engine, bank 2 typically refers to the side of the engine that doesn’t house cylinder #1. The “A” sensor is commonly found on the intake camshaft side. It’s important to note that the P0018 code is often associated with other CKP sensor-related codes such as P0016, P0017, and P0019.

P0018 code often shows up together with P0016, P0017, and P0019, which are all CKP-related trouble codes. (Image credit: Mbworld)

The CMP sensor A for bank 2 is responsible for monitoring the position and rotation speed of the camshaft. In contrast, the CKP sensor detects the position and rotation speed of the crankshaft. The Powertrain Control Module (PCM) relies on these signals to properly synchronize the camshaft and crankshaft.

When the PCM detects that the crankshaft and camshaft signals are out of time by a specific number of degrees, it triggers the P0018 code. This means that the correlation between the signals from the CMP sensor A for bank 2 and the CKP sensor is not within the expected parameters. The specific number of degrees may vary depending on the vehicle and manufacturer.

Special Notes

The systems/components involved in triggering this code can vary depending on the specific car brand and model. For example, in General Motors (GM) vehicles, the issue may be related to the CMP actuator solenoid or the timing chain. In Subaru vehicles, it may be associated with the active valve control system (AVCS) and related DTCs. In Ford vehicles, the code may refer to the Variable Camshaft Timing (VCT) system.

Many car manufacturers have issued Technical Service Bulletins (TSBs) related to the P0018 code, indicating a known issue and providing guidance for diagnosis and repair. For instance, the GM TSB 18-144-453 highlights potential causes and solutions for this code. The Subaru TSB 02-163-16R provides inspection and repair procedures for AVCS-related DTCs, including P0018. The Ford TSB 18-2360 addresses concerns with Bank 2 VCT in specific models.

Reminder: Consult the relevant TSBs specific to your vehicle’s make, model, and year for detailed information on diagnosing and resolving the P0018 code.

P0335 – Crankshaft Position Sensor “A” Circuit

The P0335 code indicates a circuit malfunction in the bank 1 crankshaft position sensor, one of the more critical sensors in many engines. It can influence the timing of your spark plug firing, and if this gets off, it can lead to misfires.

Fixing the P0335 trouble code is important, and you want to do it promptly. Read on below to learn how to diagnose and repair this potentially serious trouble code.

P0335 Code Definition

P0335 Code Definition (Generic): Crankshaft position sensor A circuit malfunction (bank 1)

P0335 Honda Code Definition: Crankshaft position sensor “A” no signal

P0335 Hyundai Code Definition: Crankshaft position sensor “A” circuit

P0335 Mercedes Code Definition: Crankshaft position sensor “A” circuit malfunction

P0335 Mitsubishi Code Definition: Crankshaft position sensor circuit

P0335 Opel Code Definition: Crankshaft position sensor circuit malfunction

P0335 Toyota Code Definition: Crankshaft position sensor “A” circuit

What Does P0335 Mean?

The crankshaft position sensor tells the engine control module (ECM), where the crankshaft is located at any point in time. In many vehicles, this information tells the spark plugs when to fire and delivers fuel to the engine in the right amounts.

The crankshaft position sensor is stationary. It works together with the reluctor ring attached to the crankshaft. The ring’s movement in front of the sensor creates the voltage wave to send to the ECM.

If the ECM doesn’t detect any voltage pulses from the crankshaft sensor, the P0335 trouble code is triggered. The reason could be a faulty sensor, but it may also be a problem with the reluctor ring, the wiring, or the circuit itself.

The P0335 OBD2 code relates specifically to the crankshaft position sensor on bank 1, also called sensor A. Bank 1 will be the side of your engine that contains cylinder 1. You may see it in conjunction with other codes related to the crankshaft position sensor, especially P0336-P0339.

Some vehicles use the crankshaft position sensor only for detecting misfires. In this case, it is a less serious code and is unlikely to be accompanied by drivability symptoms. Suppose the crankshaft position sensor controls the spark plug timing. In that case, activation of the P0335 trouble code will enable your car’s failsafe mode, making it especially important to find the root of the problem as soon as you can.

What Are The Symptoms Of The P0335 Code?

The presence and severity of symptoms vary greatly between makes and models. Possible symptoms include:

Activation of the check engine light
Stalls or hesitation from the engine
Hard starts
Rough running and misfires
Reduced gas mileage
Reduced engine power
The engine won’t start

What Are The Causes Of P0335?

A faulty or damaged crankshaft position sensor
Damaged reluctor ring
Damaged or loose wires around crankshaft position sensor
The shorted or open sensor output
The short or open ground in the wiring harness
Broken or skipped timing belt/timing chain
Faulty ECM or PCM

How Serious Is The P0335 Code?

The P0335 trouble code is very serious if you’re experiencing any drivability symptoms. Continuing to drive could cause long-term engine damage, and your car will possibly not start until you’ve fixed the issue.

If the only symptom is the activation of the check engine light, P0335 is of moderate severity. It will help if you still repair it as soon as possible, but you can drive your car in the interim.

How To Diagnose The P0335 Code

Tools You’ll Need:

Method:

If your engine will turn on, use the OBD2 scan tool to check if you’re getting an RPM reading. Rev the engine while in the park and check if the reading changes.
Inspect the wiring harness and all wires connected to the crankshaft sensor for damage. Ensure that all connections are secure.
Check the reluctor ring and timing chain/timing belt for damage. Replace or repair as needed.
Remove the crankshaft position sensor and inspect the tip for metal shavings or other damage. You may be able to wipe the metal shavings away, but if the sensor is badly damaged, it needs replacing.
Test the crankshaft sensor’s wires with a digital multimeter set to DC voltage at a low range. Turn on your ignition without starting your engine and touch the multimeter’s black lead to the negative battery post. Test each wire by touching the red lead to it. One wire should read a reference voltage of 1.5 volts. If it doesn’t, the wiring harness is faulty.
If the wiring is good, use the multimeter to test your sensor. Reinstall the crankshaft position sensor but leave the electrical connector unplugged. Set your multimeter to Ohms and touch one lead to each sensor pin. An infinite reading indicates an open circuit, while a zero reading indicates a short.
Read the wave pattern from your crankshaft position sensor. The vehicle’s manual will tell you what the resistance reading should be. If the reading is outside specifications, the crankshaft position sensor is likely faulty.

Common Mistakes To Avoid While Diagnosing The P0335 Code

A faulty crankshaft position sensor is the most common cause of P0335, but you should still conduct a full diagnosis before replacing it. Don’t overlook the timing belt, reluctor ring, or wiring harness in your rush to repair the issue.

What Should You Do To Fix The Code P0335?

Replace any faulty wiring or damaged components found in your diagnosis.
Replace the crankshaft position sensor and re-check the resistance reading and wave pattern.
If you’ve followed the full diagnosis above and the code still will not clear, you may have a more serious electrical issue. Take your vehicle to a mechanic for further diagnosis.

P0452 – Evaporative emission system pressure sensor/switch low

The P0452 OBD2 code is one of the milder diagnostic trouble codes you’ll come across. In about 75% of cases, the fix is as simple as tightening your gas cap. Even when the underlying issue is more serious, it won’t affect your engine performance.

The main negative side-effect you’ll see from P0452 is a rise in harmful emissions. Considering it’s often an easy code to clear, that’s reason enough to make the necessary repairs.

P0452 code definition

P0452 (generic): Evaporative emission system pressure sensor/switch low

If you want to learn about the P0452 OBD2 code, this is the right place

What does P0452 mean?

Your vehicle evaporative emission control (EVAP) system limits the fuel vapors that escape into the atmosphere in your exhaust. The system’s main component is the charcoal canister, which purges the fuel vapors, trapping harmful particles.

The engine computer monitors the pressure in the EVAP system. Generally, the system’s pressure rises as the temperature goes up and lowers when the stored vapors in the charcoal canister are purged. Depending on the manufacturer, this is tracked either by the fuel tank pressure sensor or a designated EVAP pressure sensor.

When the engine control module (ECM) or powertrain control module (PCM) detects the voltage from this sensor is below standard parameters, the P0452 OBD2 code is triggered. Usually, the code will only trigger after this low voltage has been recorded for a designated length of time, though this varies from one manufacturer to the next.

The EVAP pressure sensor may be located inside the fuel purge line or at the top of the fuel tank. Check your vehicle manual to find out where the sensor is in your engine.

The EVAP system and fuel system are closely linked. Improper pressure in the fuel tank can cause the P0452 code to activate, especially if you also see trouble codes related to the fuel pressure. Vacuum leaks and faulty wiring can also be responsible for P0452.

Many vehicles have an extended warranty on EVAP system components, up to 100,000 miles for some manufacturers. If it seems you’ll need to replace components to clear the P0452 code, check your warranty before buying any parts, as they’ll likely be covered.

What are the symptoms of the P0452 code?

In many cases, you won’t notice any drivability symptoms when the P0452 trouble code is active. The most common symptoms include:

Activation of the check engine light
The smell of fuel in the exhaust

The P0452 code is related to the part of a vehicle’s evaporative emission control system.

What are the causes of P0452?

Faulty EVAP pressure sensor or fuel tank pressure sensor
Faulty or loose wires around sensors
Opens or shorts in EVAP system wires or wiring harness
Faulty electrical connections
The gas cap is loose, leaking, or missing
Vacuum leaks in the EVAP system
Plugged or pinched lines in the fuel system
The charcoal canister is clogged or damaged

How serious is the P0452 code?

On its own, the P0452 diagnostic code is of low severity. You won’t notice any change in the vehicle’s operation, and the risk of further damage to the engine is low. While you will want to make repairs before your next emissions test, you can safely drive for a short time with this code active.

How to diagnose and fix the P0452 code

Tools you’ll need:

Check for any technical service bulletins related to the P0452 code for your vehicle. Follow the suggested repairs for your make and model before proceeding with the general diagnosis below.
Read all codes using an OBD2 scan tool. Address any other codes that come up first, especially if you read other EVAP system codes (P0450-P0459). Clear the codes and test drive your vehicle, then rescan to see if you’ve addressed the problem.
Check your gas cap. If it’s loose, tighten it, and clear codes/rescan. If P0452 comes back, remove the gas cap and inspect it for cracks or wear. Pay close attention to the threads, and clean away any debris or dust that may be impeding a complete seal. Even if you don’t see any damage, you may want to replace the gas cap. It’s a very cheap component to replace and is often the root of P0452 problems.
Read the freeze frame data using an OBD2 scanner. Check the fuel tank pressure data to verify the computer is reading a vacuum. If it’s not, this indicates either a wiring issue, a vacuum leak, or a faulty sensor.
Visually inspect the wiring around the EVAP sensor and fuel tank pressure sensor. Replace any wires that are frayed or damaged and inspect the connections for build-up or corrosion. If you found any loose or faulty wires, clear the codes and rescan.
Use a smoke machine to test your EVAP system for leaks. You can do this by pinching off the vent tube flowing to the EVAP vent control valve, then pressurizing the EVAP system and connecting it to a smoke tester. If there are any leaks, the smoke will give you a visible indication. Replace any leaking hoses or gaskets you discover.
If there were no leaks, or if these repairs don’t clear the code, the issue is most likely with the sensor itself. Use a multimeter to check the voltage of the EVAP pressure sensor and fuel tank pressure sensor. Compare the readings to the specifications in your vehicle repair manual. Take another set of readings while you apply pressure with the smoke tester. If the readings don’t align with specifications, replace the sensor.

Common mistakes to avoid while diagnosing the P0452 code

Check the obvious and cheap fixes before you start replacing components. The repair could be as simple as tightening the gas cap or reconnecting a loose wire.

Tips to avoid P0452 in the future

The majority of P0452 codes trigger when the driver doesn’t fully close the gas cap after filling up the tank. Taking a second to double-check that the gas cap is screwed on tightly ensures your fuel system can create a proper vacuum, preventing the activation of many EVAP codes.

The P1151 Diagnostic Trouble Code (DTC) is a common issue encountered by Ford vehicle owners and is defined as “Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Lean Bank 2”. This code is indicative of a problem within the upstream oxygen (O2) sensor. Specifically, it signals an issue with the air-fuel mixture, where the system is operating in a lean condition.

In simpler terms, there might be either insufficient fuel or an excess of air in the air-fuel mixture. The engine’s PCM continually adjusts this mixture to maintain optimal performance, but if the oxygen sensor detects a persistently lean environment for an extended period, it triggers the P1151 code.

P0341 – Camshaft Position Sensor “A” Circuit Range/Performance

The P0341 trouble code indicates your vehicle’s ECM has detected a problem with the signal coming from the Camshaft Position Sensor. The ECM must detect a valid and accurate signal from the cam sensor, as it is used to control fuel injector and ignition timing. If you are experiencing a P0341 trouble code, read on for details on how to diagnose and repair the problem.

P0341 Code Definition

P0341 Code Definition (Generic): Camshaft Position Sensor “A” Range/Performance

If you want to learn about the P0341 OBD2 code, this is the right place

What Does P0341 Mean?

The Camshaft Position Sensor is an essential input to the Engine Control Module. It allows the ECM to monitor your engine’s camshaft’s exact position, allowing it to make adjustments to fuel injector and ignition timing. When the signal is present but out of a specified range or missing altogether, a P0341 will be set, usually accompanied by a long crank to start or an engine that will not start at all.

What Are The Symptoms Of The P0341 Code?

P0341 can cause many driveability symptoms. Some of the more common symptoms are:

Illuminated check engine light
Long crank to start
No start
Stalling

What Are The Causes Of P0341?

The P0341 trouble code means there’s a problem with the signal coming from the Camshaft Position Sensor

Defective Camshaft Position Sensor
Faulty wiring
Improper air gap/installation

How Serious Is The P0341 Trouble Code?

P0341 is a severe trouble code. This code can cause your vehicle to stall or not run at all. The camshaft position sensor is a critical input to the ECM and should be diagnosed and repaired right away.

How To Diagnose And Fix The P0341 Code

Use a scan tool to scan for trouble codes and record freeze frame data. If there are other codes related to camshaft or crankshaft timing, they can help diagnose P0341.
Perform a thorough visual inspection of all related wiring. Check for any broken or chafed wiring, misrouted harnesses, and ensure that all connectors are tight and not corroded. Also, verify that the Camshaft Position Sensor is installed correctly and seated flush.
Next, check the internal resistance of the sensor. To do this, set your DVOM to ohms and disconnect the connector for the Cam Sensor. Use a wiring diagram to test the resistance across the sensor signal terminal and the sensor ground terminal. If resistance is infinite or the circuit is open, the sensor should be replaced. If not, verify the specification in your service manual.
If the sensor passes the resistance test, depending on your vehicle sensor’s circuit configuration, you may have a 5-volt reference signal. Check your wiring diagram and verify that this terminal has 5 volts coming from the ECM with the ignition key in the run position.
The best way to verify the Camshaft Position Sensor signal is to use an oscilloscope to give yourself a signal’s visual waveform. But this is a relatively advanced diagnostic tool that most non-professional technicians are not able to use. You can get a rough idea of the signal health by checking it with your DVOM set to AC voltage, and reading in the millivolts indicates that the sensor is at least producing a signal.
If none of these tests produce any results, you may be dealing with a valve timing issue. Some vehicles have not been appropriately maintained, such as not replacing a timing belt at the suggested interval or lack of oil changes on a vehicle equipped with a timing chain. The belt or chain has likely jumped teeth on one of its gears in those vehicles. You can check this by disassembling the engine enough to check the cam and crankshaft’s timing marks visually. Or using an oscilloscope to compare the cam and crank sensor signals.

Common Mistakes To Avoid While Diagnosing The P0341 Code

When diagnosing a P0341 trouble code, it is vital to make sure the wiring is routed correctly and not pulled too tightly or chafing on other components. Also, a faulty Crankshaft Position Sensor has been known to cause P0341 on certain vehicles. It is always a good idea to verify the Crankshaft Position Sensor operation when diagnosing a P0341.

Tips To Avoid P0341 In The Future

To help avoid P0341 in the future, always route wiring harnesses in their original position to avoid wires and connectors from being stretched or rubbing on other components. And following the manufacturer’s maintenance schedule will reduce the risk of having any actual valve train timing problems.

P0299 – Turbocharger/Supercharger “A” Underboost Condition

The trouble code P0299 indicates that your vehicle’s turbo or supercharging system is creating an underboost condition. Generally, problems in your turbo/supercharger system should be taken seriously and repaired as soon as possible to prevent more serious and expensive engine damage. If you are experiencing a P0299, continue reading to learn more.

P0299 Definition

P0299 VW/Audi Definition: Boost Pressure Regulation, Control Range Not Reached

P0299 Ford Definition: Turbo/Supercharger Underboost Condition

P0299 Chevy Definition: Turbo/Supercharger Underboost Condition

Here’s where you can get a thorough understanding of the P0299 OBD2 code

What Does P0299 Mean?

On vehicles equipped with a turbo or supercharger, air entering the engine is compressed and generally cooled before entering the intake manifold. This feature allows the engine to create substantially more power than engines without turbo or superchargers. When you experience a P0299 trouble code, the ECM has determined that your forced induction system is not producing enough boost.

As the vehicle is working, incoming air is compressed and then forced into the intake manifold. This pressurized air is called a “boost” and is monitored and regulated by the PCM. The boost the PCM allows the turbo/supercharger to create varies due to different operating conditions and driver inputs. The PCM compares the amount of the desired boost to the amount of the actual boost. If the actual boost cannot reach the desired level, the check engine light will be illuminated, and the car may enter “limp mode.”

The P0299 code means the ECM has determined that your forced induction system is not producing enough boost.

What Are The Symptoms Of The P0299 Code?

The P0299 code will usually be accompanied by a few noticeable symptoms that include:

Activation of the check engine light
Low engine power
Unusual engine noises
Black smoke from the exhaust

What Are The Causes of P0299?

Failed turbo or supercharger
Intake air/book leak
Vacuum leak
MAP or boost pressure sensor failure
Turbocharger wastegate and/or solenoid failure

How Serious Is The P0299 Code?

P0299 is a serious code. Failure to properly diagnose and repair the air induction system on a turbo or supercharged vehicle can potentially result in severe and expensive engine damage. It is common for a turbocharger to fail internally and cause scraps of metal to be introduced into the engine.

How To Diagnose And Fix The P0299 Code

8 steps to diagnose and fix the P0299 code

Diagnosing a P0299 can vary widely from make to make, so consulting a service manual with vehicle specific information is highly recommended. But here are some general guidelines to follow.

Scan the vehicle with a scan tool and record all codes and freeze frame data. If there are any other codes related to engine performance, including EGR, repair them first.
Next, perform a thorough visual inspection of all boost piping and hoses, air intake system, and vacuum lines. Make sure all clamps are tight and properly positioned. If any leaks are found, repair or replace the component.
If no leaks are visible, it may be necessary to use a smoke machine or introduce low pressure compressed air into the intake system to check for leaks.
Once you have verified there are no leaks, remove the pipe from the turbo’s outlet side and look at the wheel/shaft for excessive side to side or up and down movement. Ensure the turbo has had time to cool off before touching, as it gets very, very hot during normal operation. If there are any signs of damage, you should replace the turbo.
Use a scan tool to compare MAP sensor readings at idle and at 2500RPM with the specifications in-service information.
If equipped with a Mass Air Flow sensor, perform the same test as the MAP sensor.
Certain cars come equipped with a boost sensor that should also be tested using the correct service information. If any of these are out of specification, replace them.
Check to make sure that the wastegate of capable of moving and is not seized in place. These are typically vacuum or electronically controlled. Again, consult service information. If it is vacuum controlled, ensure that the control solenoid has a steady vacuum with the engine running. Use a scan tool to perform a functional test of the vacuum solenoid to verify that the solenoid can open and close and the PCM is capable of controlling it.

Please use the above steps as a general guideline for diagnosis. The forced induction systems used by different vehicles make dramatic differences, so it would be impossible to cover each vehicle specific test in the space provided.

Common Mistakes To Avoid While Diagnosing The P0299 Code

Remember to check the engine air filter, and a dirty filter could not allow enough air into the intake system, causing a low boost condition. Also, on some cars, a fault in the EGR system can cause P0299, so repair EGR issues first. And, remember, just because you can’t see a leaking air pipe or hose with the engine off doesn’t mean it isn’t leaking under boost pressures.

Tips To Avoid P0299 In The Future

As usual, proper maintenance is key! Make sure to change your oil using the appropriate oil viscosity and specifications. The engine oil also lubricates your turbo/supercharger, so this is very important. Please do your best to keep rodents out of your engine bay, as they tend to destroy vacuum lines and electrical wires. And before shutting off your car, let it idle for a minute or two to allow the turbo to cool before cutting off its oil supply when shutting down the engine.

When encountering the P1778 code, the first step is to check for any related Technical Service Bulletins (TSBs) from Nissan. These TSBs contain valuable information and recommended actions for specific vehicle models. By consulting the relevant TSB for your specific car, you can determine if your vehicle falls under a recall campaign or if there are particular actions you should take to address the P1778 code.

Special Note Regarding P1778 Nissan Code – Transmission Reverse I/P Circuit Fault

The P1778 Nissan code can have different definitions depending on the car model. The most common definition, which this article focuses on, relates to the Step Motor Function within the CVT system. However, it’s worth noting that this code may be defined as a Transmission Reverse I/P (Input/Output) Circuit fault in certain car models.

This fault occurs when there is a discrepancy between the number of steps for the stepping motor and the actual gear ratio. It is a functional code, rather than a circuit code, for the step motor.

Unfortunately, this issue is often caused by a failing CVT transmission. However, there is some positive news to consider. Nissan has introduced an extended warranty for 10 years and 120,000 miles on the CVT of certain models. Consult with your nearest Nissan dealership or authorized service center for more information if you’re experiencing the Transmission Reverse I/P Circuit fault code.

How Serious Is The Nissan P1778 Code?

The severity level of the P1778 code in Nissan vehicles can be considered medium. It does not pose an immediate safety risk or cause the vehicle to become inoperable. Therefore, it is generally safe to continue driving with this code present.

However, it is essential to address the issue as soon as possible to prevent further damage to the transmission and ensure optimal vehicle performance. Ignoring the code for an extended period may lead to transmission-related problems, such as erratic shifting or reduced fuel efficiency.

P0113: Intake Air Temperature Sensor 1 Circuit High

What does the P0113 code mean?

Can you continue to drive your car with it, and what are the aftereffects?

Here is a quick evaluation of the problem!

P0113 Definition: Intake Air Temperature Sensor 1 Circuit High
Code type: Generic – P0113 indicates the same problem whether you’re having a Ford, Honda, or Toyota, etc.
Can I Drive with the P0113 code? Yes. It is not severe, and the car is safe to drive.
Easy to fix? Intermediate-advanced level.
Cost: $50-$200 (common)

Read on for detailed information about what P0113 is, its causes, and how to identify and fix it.

What Does The P0113 Code Mean?

P0113 is a diagnostic trouble code (DTC) for “Intake Air Temperature Sensor 1 Circuit High”.

The car’s computer sets this code if it detects the Intake Air Temperature (IAT) sensor’s voltage is higher than 4.6V.

This number tells the computer that the intake air temperature is abnormally low (40°F.)

How Do IAT Sensors Work?

An IAT sensor provides the temperature of the air going to the engine.

The combination of air temperature and air volume indicates air mass.

Based on the data received, PCM adjusts fuel added to the air-fuel ratio.

The colder the air gets, the heavier it becomes and the higher the IAT output voltage.

The voltage usually ranges from 0.5 to 4.5.

What Will Happen When P0113 Is Set?

If the IAT sensor is missing, the data is 4.6V (- 40°F). That tells the PCM that the temperature is cold (but it’s not). The computer doesn’t believe in that information and enters the Failsafe mode to avoid engine damage.

Instead of working with the incorrect data, the computer chooses a constant number to believe in. Usually, most cars will pick 100°F. This allows the engine to run optimally and with minimal damage.

If the actual intake air temperature goes below 100°F, the air is colder than what the computer knows. That causes more air to be sucked into the engine, which results in a lean condition.

On the other hand, an actual intake air temperature above 100°F makes the air hotter. That means less air gets in the engine, leading to a rich condition.

None of these conditions are desirable.

P0113: Causes, Symptoms, And How To Fix

Symptoms

P0113 will show the following common symptoms:

Check engine light comes on
Engine experience a hard start
Lower fuel efficiency
Reduced engine performance – vehicle hesitates to accelerate
Rough idle

Causes

There are only three main causes for the P0113.

Cause #1: Faulty Or Loose IAT Sensor

If the IAT sensor is faulty or loose, it will be sending incorrect data to PCM. The PCM detects that and sets the P0113 code.

The solution is to replace the faulty IAT sensor or make it tighter in its socket if that was the cause of the malfunction.

Cause #2: Defective IAT Sensor Wiring

IAT sensor data goes to PCM through the signal wire. An open signal circuit will lead to high IAT voltage output.

Check the IAT sensor circuit for open, or loose wires and fix them accordingly. Damaged ones should be replaced.

Cause #3: Faulty MAF Sensor

Some vehicles have the IAT attached to the Mass Air Flow (MAF) sensor. So, when the MAF is gone, the IAT is gone.

In this case, if the MAF is bad, cleaning or replacing the MAF may fix P0113.

For those who love to fix cars at home, Scotty Kilmer must be a familiar name when it comes to DIY videos. Let’s find out how this man replaced the MAF sensor properly!

Cause #4: Faulty PCM (rare)

PCM rarely becomes faulty and this should be your last conclusion. The most common problem is a bug in its software or damage resulting from a short circuit, lightning, or impact.

Replacing the PCM is the best option in this case.

This is a complicated and expensive procedure so you may need a qualified automotive technician to help you.

P0113 Causes Identification: How to Diagnose

Solving the P0113 code problem involves diagnosing the causes, one after the other, and eliminating them. Proceed as follows:

Check The IAT Sensor

Start by visually inspecting the IAT sensor for loose terminal connections and dirt. If that is the case, tighten and clean everything.

The next step is to test the resistance across the IAT sensor terminals. If you get infinity resistant or OL (out of limit) reading, it is faulty. So, replace it.

In case the IAT is attached to the MAF, locate the IAT thermistor and repeat the above process.

Check IAT Sensor Wiring

Use an OBD2 scanner to view the live data from the IAT sensor with the sensor removed from its socket. The reading should be -40°F.

Repeat the process, but this time short the two pins with a jumper wire. The new value should be maxed out (around 285°F). That shows the IAT sensor wiring has no problems.

If you get different values, there is an issue with the IAT sensor wiring. So, use a wire tracker to find where it is open and fix it appropriately.

Check PCM

After checking both the sensor and its wiring, if they are not the problem, it can be because of the PCM.

9 out of 10 times, the IAT sensor or its wiring will reveal itself as the problem when you perform the above diagnosis. If it’s not, having a mechanic inspect your PCM is the next thing you should do.

How Much Does It Cost To Fix The Code P0113?

The cost of fixing the P0113 code varies depending on your car’s make, model, and year. Also, the part to be replaced influences the price tag.

The most common problem is a faulty IAT sensor, which typically costs $20-$150 to replace by yourself.

The Estimated Repair Cost Of P0113

Solutions	Repair cost
Replace the IAT sensor	DIY: $20-$150 Mechanic: $40-$250
Fix IAT sensor wiring	DIY: $0-$20 Mechanic: $20-$75
Replace MAF sensor	DIY: $30 to $300 Mechanic: $80 to $380
Replace PCM	DIY: not recommended Mechanic: $1,000-$3,000

Note: The data in this table was collected in June 2022. The actual price depends on many factors, such as your car’s make and year, mechanic’s rate, etc.

You Ask, I Answer

The P0113 code should not make you panic. Your car should still be drivable if it has the failsafe feature, and the cost of fixing it is relatively low, about $20-$150 for replacing the IAT sensor.

What Does The P0741 Code Mean?

P0741 is a transmission DTC code triggered when the difference in speed between the torque converter and the transmission input shaft is greater than 200 revolutions per minute (RPM) and less than 7,500 RPM for 5 seconds.

Under normal conditions, the required ratio of these is 1 to 1 when the torque converter locks up. If this ratio is not achieved, PCM will set the P0741 code to warn you that the torque converter clutch circuit is stuck off or out of performance.

If the P0741 error code appears, sometimes it can be understood that there is a problem with the torque converter clutch, TCC solenoid, or the circuit.

P0741 Causes Identification: Quick View

P0741 can be attached with other codes in some cases for you to determine the causes easier.

Note: The causes for each code combination are the most common ones. There can be some uncommon issues hidden under those codes.

So, it’s important to fully understand the correlation between your car’s symptoms and the true causes.

The below part will help you pinpoint your problems and how to fix them.

P0741: Causes, Symptoms, and How To Fix

Cause #1: Faulty Torque Converter Clutch

The TCC starts locking up after using the first gear and always stays locked up from there.

As I mentioned, the p0741 code is set on the powertrain control module (PCM) when there is a slip (different in speed) between the engine and the transmission input shaft at the time TCC is locked. This could mean the TCC doesn’t lock properly or is in an open state permanently.

The TCC starts locking up after using the first gear and always stays locked up from there. If the clutch doesn’t engage anymore, the symptoms are:

Sometimes, only P0741 appears; sometimes, the combination between P0741 and P0729 to P0736 appears.
Poor fuel economy.
Decreased transmission fluid life.
Transmission fluid getting hot ( >240F).

How to replace the torque converter for an automatic transmission from 2carpros.

Cause #2: Faulty/Internal Short In Torque Converter Clutch Solenoid

The TCC solenoid controls the fluid flow to the torque converter. If the solenoid is faulty, it can’t measure how much transmission fluid is needed, which could cause unusual fluid pressures.

As a result, it can create a lot of irregular behaviors, such as

Sometimes, only P0741 appears; sometimes, the combination between P0741+P0218 or P0741 + P1744 (Ford) or P0741 + P0729 to P0736 appears.
The fuel consumption increases.
The transmission may be jammed.
The TCC solenoid erratic shift.
Check engine light.

To test the TCC solenoid, measure the OHMs and make sure it is within a suitable range (12-28 Ohms).

If it is not, then replace it.

Torque converter clutch solenoid testing and replacement from CarsNToys.

Cause #3: Defective Or Damaged Wires Around TCC Solenoid

It’s not hard to check the TCC solenoid wires. Test your TCC solenoid wire carefully to ensure that you don’t miss any problems.

Remember that the bad wire is zero ohms, and the good wire is slightly more than zero ohms.

If the wire goes bad, the P0741 popped up.

If you have a Ford, in some cases, P0741 and P1744 will appear to make you know this specific cause.

Cause #4: Damaged Transmission Wiring Harness

The faulty transmission wiring harness can cause the difference in speed between the torque converter and the transmission input shaft.

The faulty wiring harness can cause the difference in speed between the torque converter and the transmission input shaft, making the P0741 set.

Inspect the wires visually for damage and check the ohms (zero ohms for bad and infinity ohms for good) to ensure you find out all of the problems.

It sometimes appears the mixing codes with P0700 and P0768.

A video about the transmission wiring harness removal from Scotties Hobbies.

Cause #5: Faulty Engine Coolant Temperature Sensor

The ECT sensor helps measure the temperature of the coolant for the ECU. If the ECT sensor goes wrong, the proper temperature signal can’t deliver to the TCC, which leads to not locking up on the highway speed.

Like other parts, the ECT sensor can be damaged due to engine-related issues, leading to severe problems.

The signs for this cause are:

A combination between P0741 and P0118.
Check engine light.
The poor mileage.
The electric cooling fan is not working.
Black smoke exhausting.
Poor idling or engine performance.

A video about how to check the ECT sensor from Auto Repair Guys.

Cause #6: Transmission Fluid Is Dirty

If the fluid is dark brown, change it right away.

The Automatic Transmission Fluid (ATF) is filled in the torque converter. The torque converter and transmission are damaged if the fluid is contaminated, contains debris or sludge, or is old.

You need to check your transmission fluid to ensure whether the transmission fluid is the cause of this code or not.

Change the fluid right away if it’s dark brown.

Sometimes, P0741 combines with P0218 or P0729-P0736. In this particular case, the P0741 can be attached with P2757 (Lexus), P0740 and P2761 (BMW), and P1744 and P0218 (Ford) in your scanner to warn you to replace the transmission fluid.

How to change the automatic transmission fluid by ChrisFix.

Cause #7: Faulty Valve Body

A transmission fluid leak is one of the signs for you to diagnose that you have a faulty valve body.

The valve body plays a vital role in the torque converter with various channels and passages in the automatic transmission. It interacts with the solenoid to push transmission fluid flow through those passages to initiate different clutches and switch gears.

The torque converter can not operate correctly when the valve body goes bad.

To know whether the valve body is good or not, there are a lot of signs for you to identify:

P0741 appears alone or with P0700, and P0768.
Incorrectly gear change.
Harsh noise.
Slipping whilst driving a manual box in the clutch.
Transmission fluid leak.

A video about the valve body replacement.

Cause #8: Faulty Transmission Control Module (TCM)

The TCM measures severe signals from the engine speed sensor and the turbine speed sensor to estimate the torque converter slip value. Then, the TCM compares this value to the value preset in the TCM calibration.

P0741 pops up when this torque converter slip value exceeds 80 RPM. The slip value is inaccurate if the TCM fails, making TCC not work correctly.

This cause has a variety of signs to identify, including:

P0741 combines with the P0700.
Check engine light.
Poor fuel mileage.
Erratic shifting.

How to replace the TCM.

How Much Does It Cost To Fix The Code P0741?

The fixing cost of the P0741 is around $15 – $700 for DIY and $100 – $1000 for a mechanic shop or dealer.

However, it is based on the causes of your car and the area where you are at.

The estimated repair cost of the P0741

P1132 Ford Code: Ignition Issues Explored

You’re behind the wheel of your dependable Ford, when all of a sudden, a warning light illuminates, signaling a potential problem. Connecting a scanner reveals a puzzling “P1132” code.

Fear not – it’s simply your car’s way of highlighting a hiccup in the engine’s performance. This article takes you on a concise journey to understand the P1132 Ford code, its causes, symptoms, and what steps you can take next.

Let’s dive in and decode the mystery together!

P1132 Ford: A Quick Overview

Check the overview of the P1132 Ford code below!

Definition: Lack of HO2S11 (Upstream Heated Oxygen Sensor) Switch – Sensor Indicates Rich – Bank 1
Severity: Medium
DIY Skill Level: Intermediate
Continue To Drive?: Yes
Estimated Repair Cost: $50 – $300

What Does The P1132 Code Mean On Ford?

The trouble code P1132 is specific to Ford vehicles and indicates an issue with the upstream heated oxygen sensor. This sensor measures the oxygen levels within the exhaust fumes, which helps the car computer (ECM) regulate the air-fuel mixture for efficient combustion. The code is triggered when the ECM detects a lack of variation in the sensor’s voltage signal.

The P1132 code on Ford is sometimes called “Lack of HO2S11 Switch – Sens Indicates Rich” besides the definition above.

In simpler terms, the oxygen sensor’s job is to tell the ECM about the amount of oxygen in the exhaust. This information helps the computer ensure the engine runs smoothly and produces minimal emissions.

The P1132 code comes up if the sensor’s signal doesn’t change as expected, indicating a problem with the sensor or its communication with the car computer. This behavior might imply that the sensor is persistently reporting one level of oxygen (either rich or lean) or not functioning as intended. This issue can affect how well the engine runs and how efficiently it uses fuel.

Note:

Please note that the upstream heated oxygen sensor refers to the sensor located before the catalytic converter.
The P1132 Ford code can sometimes be accompanied by other related codes, like P0171, P0172, P1131 Ford, P1152 Ford, etc., especially if the issue is affecting multiple components of the vehicle’s emissions and fuel system. However, it’s not always guaranteed that additional codes will be present alongside P1132.

How Severe Is The P1132 Ford Code?

The P1132 Ford code can be classified as having a moderate severity level, which means that while immediate catastrophic failure might not be imminent, it’s important not to underestimate the potential impact on your vehicle’s performance, emissions, and safety.

In the short term, you might be able to continue driving with the code present, but it’s strongly recommended to address the issue as soon as possible. Neglecting a malfunctioning oxygen sensor can gradually lead to decreased engine efficiency, reduced fuel economy, and increased emissions. Over time, these effects could compound and potentially cause further complications.

What Are The Symptoms Of The P1132 Code On Ford Vehicles?

The P1132 Ford code is often associated with a range of symptoms that can provide clues to the underlying issue. While not all symptoms might be present in every case, here are some common signs that you might experience when this code is triggered:

P0102 – Mass Air Flow (MAF) Circuit Low Input

Your scan tool throws the P0102 code?

Here is a quick brief to let you know what you’re facing and what to expect.

P0102 definition: Mass Air Flow (MAF) Circuit Low Input.
Code type: Generic – P0102 indicates the same problem whether you’re having a Chevy, Ford, or Nissan, etc.
Can I drive with the P0102 code? Yes, but extended driving can lead to costly repairs.
Easy to fix? Beginner to intermediate DIY level.
Cost: $30 to $380.

Keep driving with this code is not that dangerous. But the best way to avoid unnecessary expenses is to get it fixed ASAP.

Now let us take a deeper look into the code!

What Does The P0102 Code Mean?

The error P0102 code is triggered when the Mass Air Flow (MAF) sensor’s voltage is lower than 0.2v for a certain period of time. This number is telling the car’s computer that the amount of intake air is abnormally low.

How Does The MAF Sensor Work?

The MAF sensor measures how much air is coming into the combustion chamber. Using this data, the computer can determine how much fuel is needed.

A typical MAF sensor has a sensing wire. This wire heats up during operation and is further cooled by the airflow. The cooling initiates a decrease in resistance leading to an increase in voltage.

Therefore, the more air is coming, the higher the MAF’s output voltage. The number usually ranges from 0.5v to 5v.

What Happens When The MAF Sensor’s Output Voltage Is Lower Than 0.2v?

The MAF sensor’s voltage being lower than 0.2v is telling the computer that there is little to no air entering the engine.

Of course, the computer does not believe in this number as it knows it’s an irrational number.

So, what data does the computer take to adjust the air-fuel mixture?

The answer is O2 sensors!

The problem is that O2 sensors are located after where the combustion takes place. For that reason, there is a delay in the air-fuel ratio adjustment. As the result, your car can run just fine when cruising but it will hesitate when you suddenly accelerate.

Other codes related to the P0102 code are P0100 and P0101.

P0102: Causes, Symptoms, And How To Fix

Symptoms

Here are some common symptoms of P0102 that you should look out for:

Check engine light on
Hard starts
Engine stalling
Rough idle
Hesitate when accelerating

Causes

Cause #1: Dirty Air Filter

The accumulation of dirt in your air filter will restrict airflow. Therefore, the MAF reports there is not enough air coming.

If this is your problem, your car can’t start (because there is actually no air for combustion.)

P0102 caused by a dirty air filter should be resolved by cleaning out the clogged air filter. This is an easy task and you can totally do it by yourself.

Cause #2: Faulty MAF Sensor

When the sensing wire inside the MAF gets dirty, airflow can not cool it down properly. This leads to the MAF’s voltage drop and it underreports the intake air mass.

The decision to replace your MAF sensor should be taken after a proper diagnosis.

Cause #3: MAF Sensor Wiring Harness Problems

Damaged MAF sensor wiring harness can contribute to your P0102 error code. The wiring could also be near components that consume higher voltage, such as alternators, ignition wires, etc. These could lead to false voltage readings as well.

Cause #4: PCM Issues (rare)

Finally, the Powertrain Control Module (PCM) will rarely be the source of your error code. A faulty PCM causes the vehicle to require multiple attempts before starting up. It may also result in the engine’s failure to start.

Replacing PCM should fix the problem. Installing this module will take about half an hour and require professional assistance to ensure proper operations.

P0102 Causes Identification: How to Diagnose

Following the recommended diagnostics process is the first step in resolving the P0102 code.

Diagnose Air Filter

First, open the hood and inspect the air filter to confirm if it is clogged or contaminated with debris. If it is the case, have your air filter cleaned with recommended cleaners.

Alternatively, when the air filter gets severely damaged, replacing it is the best option.

Diagnose MAF Sensor

After making sure that the air filter is clean, the MAF sensor is your next target.

The sensor is located between the air filter and the intake manifold. While the car is idling, unplug the MAF sensor, and the car should stall.

If it doesn’t, the MAF need to be cleaned or replaced.

As a motorhead, you must be familiar with the name Scotty Kilmer. He is famous for his DIY videos on car stuff. Let’s find out how this man replaced the MAF sensor properly!

Diagnose MAF Sensor Wiring Harness

Now, ensure you check the wiring of your MAF sensor thoroughly to inspect any broken, loose, frayed, or pinched cables and connections. Verify that the wiring harness is perfectly coupled to the MAF sensor.

Diagnose PCM

After eliminating all of the above possibilities, the last thing you should check is the PCM.

Up to this point, I recommend you have a mechanic inspect the PCM. This is a complicated and expensive process.

But don’t worry, this is a very rare case.

How Much Does It Cost To Fix The Code P0102?

Most of the time, replacing the MAF sensor will fix P0102. This is an easy fix and costs you about $30 to $150 to buy a new sensor.

The Estimated Repair Cost Of P0102

Solutions	Repair Cost
Replace faulty MAF sensor	DIY: $30 to $150 Mechanic: $80 to $380
Clean dirty air filter	DIY: a few bucks Mechanic: $15 to $85
Replace PCM	DIY: not recommended Mechanic: $1,000 to $3,000

Note: The data in this table was collected in June 2022. The actual price depends on many factors, such as your car’s make and year, mechanic’s rate, etc.

You Ask, I Answer

The P0102 code is not as serious as you worry, but ignoring it could lead to further damages that cost an arm and a leg to repair.

P0463 Ford Code Definition: Fuel Level Sensor A Circuit High Input

P0463 Jeep Code Definition: Fuel Level Sensor 1 Circuit High

P0463 Nissan Code Definition: Fuel Level Sensor “A” Circuit High

What Does P0463 Mean?

The fuel level sensor in your engine is how your vehicle’s computer knows how much fuel is left in the tank. This information is sent along to the powertrain control module (PCM) or engine control module (ECM) and adjusts the indicator on the dash accordingly.

Functionally, the fuel level sensor consists of a float attached to an arm. This arm is grounded through the tank or a dedicated circuit. As it raises or lowers, the resistance to the ground changes, and the voltage vary to indicate the fuel level change.

In many cases, the fuel level sensor is built directly into the fuel pump. While there are exceptions, you usually can’t replace one without replacing the other.

The specific voltage of your fuel level sensor varies depending on the make and model. Commonly, it operates at 5 volts. You can find a particular voltage for your vehicle in your manual.

If the fuel level sensor tells the ECM or PCM, there is more fuel in the tank than it can hold, the P0463 code triggers. Normally, the voltage has to be higher than the threshold for a designated length of time before activating the code.

What Are The Symptoms Of The P0463 Code?

Activation of the check engine light
The fluctuation of the fuel level gauge
Incorrect empty or full readings from fuel level gauge
Illumination of fuel light

Faulty ECM or PCM (less common)

How Serious Is The P0463 Code?

The P0463 trouble code is of low severity. Your vehicle will run without problems while the code is active. The most troubling thing about this code is that you won’t be able to trust your fuel gauge until it’s fixed. This could lead to you becoming stranded due to low fuel. For this reason, you should fix the issue as soon as you can.

How To Diagnose And Fix The P0463 Code

Tools You’ll Need:

Method:

Scan your vehicle using an OBD2 scan tool. Check if any other codes are present. You may see other codes related to the fuel sensor (P0460-P0464). Clear the codes, then test drive your vehicle to see if the P0463 code returns.
Read the freeze frame and fuel gauge data using the OBD2 scanner. Compare these readings to assess how much the fuel reading is varying from the actual level. Add a gallon or two of fuel to your tank and recheck the readings to see if they’re changing accordingly.
Visually inspect the wiring on the fuel level sensor wiring harness. Replace any that are frayed, corroded, or otherwise damaged. Ensure all connections are secure, then clear the codes again and take another test drive to see if the issue has been resolved.
In some cases, when a rock or other road hazard damages the fuel tank, it can also damage the fuel pump or fuel level sensor. Check the exterior of the fuel tank for signs of impact or damage. Also, make sure the ground strap is not missing, corroded, or rusty. If it is, replace it as needed.
Check the ground circuit for opens, shorts, and high resistance using a digital multimeter. Connect the black lead to the negative battery terminal and the other to the fuel level sensor ground where it meets the tank. Turn on your engine and check the reading. It should be lower than 100 millivolts (.1 volts). If it is closer to 1 volt, there is an issue. Clean or replace the sensor ground and test it again.
If the code still does not clear, you likely need to replace the fuel level sensor. Electrical issues in rare instances can trigger this code; however, it can also be the result of the problems with the instrument cluster. As these problems are difficult for a non-specialist to diagnose, it’s recommended you take your vehicle to a mechanic for further diagnosis before replacing any significant components.

Common Mistakes To Avoid While Diagnosing The P0463 Code

Some mechanics replace the fuel level pump before they’ve fully diagnosed the issue. Don’t forget to check the wiring and ground for issues before replacing any components. This could save you from making unnecessary and costly repairs.

What Does The P1564 Nissan Code Mean?

P1564 is a diagnostic trouble code (DTC) that pertains to Nissan’s ASCD system. This code is triggered when the Engine Control Module (ECM) detects irregularities in the ASCD steering switch’s electrical signals. This occurs when an excessively high voltage signal is sent from the ASCD steering switch to the ECM, the input signal from the switch is out of the specified range, or the switch is stuck in the ON position.

Let’s learn about the ASCD system. The ASCD steering switch consists of multiple buttons, each associated with specific cruise control functions like setting the desired speed, resuming previous speed, or canceling the system. The switch’s buttons have unique electrical resistance values, and when a button is pressed, the ECM reads the corresponding voltage variations to determine the intended function. So when the voltage is abnormal in the ASCD’s electrical signal, the P1564 is set.

This code is mostly common in Nissan Titan, Xterra, Murano, Pathfinder, and Nissan Maxima vehicles.

The A/F sensor, or HO2S, is a critical component in the fuel system as it measures the oxygen content in the exhaust gases. This information helps the ECM adjust the air-fuel mixture for optimal combustion efficiency. Therefore, encountering the P1168 code suggests a fault with the A/F sensor or its circuitry.

P2096 Nissan Code Definition: Post Catalyst Fuel Trim System Bank 1

If you want to learn about the P2096 OBD2 code, this is the right place

What Does P2096 Mean?

The right mix of air and fuel is crucial to maintaining your engine’s proper operation. And it’s a particular ratio: 14.7 parts air to each 1 part fuel. The oxygen sensors measure the air to fuel ratio in your exhaust stream to verify it’s in keeping with these specifications.

Most modern engines use two oxygen sensors.

The one upstream of the catalytic converter is labeled oxygen sensor 1.
A second sensor is positioned downstream of the catalytic converter and is referred to as sensor 2.

Usually, oxygen sensor 1 will report a higher fuel ratio than oxygen sensor 2.

When the air ratio to fuel is too high, it’s a lean condition. Depending on how lean the engine is running, this could reduce your engine performance and lead to misfires. Because of this, the powertrain control module (PCM) or engine control module (ECM) regularly monitors and adjusts the air to fuel ratio throughout the drive cycle.

Fuel trim is the term for these adjustments made by your engine’s computer. When the PCM or ECM detects that more fuel needs adding to the mix, it will trigger the P0505 and make the necessary adjustments.

There are two main reasons your vehicle could run lean. Either too much air is being introduced to the system or not enough fuel is being released. Identifying which is the case is critical for an accurate diagnosis.

What Are The Symptoms Of The P2096 Code?

Depending on the source of the P2096 trouble code, you may not experience any drivability symptoms. The code’s most common symptoms include:

Activation of the check engine light
Rough idle
Knocking from the engine
Engine misfires
Difficulty accelerating
Reduced gas mileage
Reduced engine performance
Catalytic converter glowing red
Sulfur or rotting egg smell in the exhaust

What Are The Causes Of P2096?

Vacuum or exhaust leaks
Damaged gaskets and o-rings in the exhaust system
Cracked or rusty exhaust manifold
Clogged filter
Clogged catalytic converter
Faulty or damaged fuel pumps
Damaged fuel pressure regulator
Defective or damaged oxygen sensor or oxygen sensor circuit
Defective or damaged mass airflow sensor

How Serious Is The P2096 Code?

The P2096 trouble code is of moderate severity. A vehicle registering this code can often continue to drive safely in the short term. However, misfires and other issues caused by an incorrect air to fuel ratio can lead to lasting engine damage. You should identify and repair the problem as soon as possible.

How To Diagnose And Fix The P2096 Code

Tools you’ll need:

Digital multimeter is one of the tools which can be used to fix the error P2096 code.

Check for any technical service bulletins related to this code for your vehicle. Many makes and models have a history of issues with a specific component. Follow any vehicle-specific repair steps recommended before beginning with the general diagnosis below.
Use an OBD2 scanner to check for other trouble codes. These can help to guide your diagnosis. Codes related to the catalytic converter, such as P0420, suggest this is the faulty component. You may also see codes related to the oxygen sensors or mass airflow sensor (especially P0100) if they are failing. Address these codes first, then clear the codes and test drive your vehicle to see if the P2096 code returns.
While the car is running, look beneath it for the catalytic converter. If it is glowing red, this likely means it’s clogged. Try taking a hard drive, pushing your vehicle over 50 MPH (miles per hour) for at least 15 minutes at a time, then slowing down quickly. Stop and recheck your catalytic converter. If it’s still red, remove and clear it.
Visually inspect the vacuum lines and exhaust system. Check for any cracks, damage, or visible leaks and ensure all the ends are secured. Also, keep your eye out for cracks in the gaskets, missing gaskets, or rust holes. Replace or tighten components as necessary.
Inspect the electrical connectors for the oxygen sensors and mass airflow sensors. Also, check the wiring for damage or disconnects. Jeeps and Chryslers are especially known for using electrical connectors that wear easily, which is often the source of the P2096 code in these vehicles.
Test the downstream oxygen sensor with a digital multimeter. If it’s faulty or shorted, replace it.

The way to fix the p2096 code.

Common Mistakes To Avoid While Diagnosing The P2096 Code

Don’t forget to clear the codes before starting your diagnosis to verify that a problem exists. Since this code triggers concurrently with the ECM or PCM’s fuel trim adjustments, the lean condition may no longer be an issue in some cases.

Tips To Avoid P2096 In The Future

The connectors, wires, and hoses in your engine are all susceptible to damage if not cared for properly. You should check them as part of your regular maintenance routine.

P0122 Jeep Code Definition: Throttle/Pedal Position Sensor/Switch “A” Circuit Low

If you want to learn about the P0122 OBD2 code, this is the right place

What Does P0122 Mean?

The throttle position sensor (TPS) monitors the movement of your throttle. When the throttle opens, it generates a voltage. The more open the throttle, the higher the voltage should be. This data is sent from the TPS to the engine control module (ECM), which monitors the overall engine performance.

The TPS has two circuits, labeled “A” and “B”. Each of these has a certain voltage range that it should report. When the “A” circuit output drops below the minimum voltage threshold, the P0122 trouble code is triggered.

Your exact TPS “A” circuit voltage range will vary depending on your vehicle’s manufacturer. Typically the lower limit should be around .2 volts, but you can find the specific voltage in your car’s manual. You’ll likely see this code appear alongside P0121 if the “B” circuit is operating correctly.

What Are The Symptoms Of The P0122 Code?

The symptoms of P0122 can vary. It will activate your engine’s failsafe mode in most vehicles, cutting power to the actuator and reducing how far the throttle can open. This will limit your maximum speed and overall engine performance.

Other common symptoms include:

Activation of the check engine light
Rough idling
Low or high idling
Stalls
Reduced acceleration or failure to accelerate
Engine surges

What Are The Causes Of P0122?

Incorrectly mounted TPS
Faulty or damaged wiring on the TPS
Short in the TPS ground
Faulty TPS
Damaged or faulty ECM

How Serious Is The P0122 Code?

The P0122 trouble code is serious. When your vehicle’s failsafe mode activates, you will have a lot of trouble accelerating and may experience frequent stalls. This makes your car unsafe to drive, as well as raising the potential risk for internal engine damage. You should avoid driving your vehicle until you’ve cleared this code.

How To Diagnose And Fix The P0122 Code

While P0122 is a generic powertrain code, the exact fixes may vary depending on your car’s make, model, and manufacturer. Check your manual for any recommended repair steps. You may also find technical service bulletins that have been released for your vehicle, suggesting specific repairs. Follow these first before proceeding with the generic diagnosis below.

Tools You’ll Need:

Method:

Scan your vehicle with an OBD2 scan tool to see if any other codes are present. You may see other trouble codes related to the TPS (P0120-P0124). Also, read the freeze frame data to check what conditions were present when the code activated.
Check the throttle position sensor to make sure it’s installed correctly. Very often, the P0122 code triggers if you don’t rotate the TPS when you’re installing it. The inside tab of the TPS must contact the throttle body’s rotating pins to operate.
Once you’ve correctly installed the TPS, verify all the connections are secure. Clear all codes using your OBD2 scanner and test drive your vehicle. Very often, this will fix the issue. If it doesn’t, continue with the diagnosis.
Visually inspect all the wiring around the TPS. Replace any that are damaged or corroded. Also, check the connectors to make sure they’re not damaged.
Compare the “A” and “B” circuit readings from your throttle position sensor. If they don’t match, check your vehicle manual for specific steps and tests to follow.
Use a multimeter to check the voltage of the TPS. You can find the correct voltage in your vehicle’s manual. If it is too low, replace the TPS.
Test the ground for the throttle position sensor using a digital multimeter; if the reading indicates an open or short, repair or replace it.

In some cases, the P0122 trouble code is an intermittent problem. You may find the code clears initially, only to recur a few days or weeks down the line. In these cases, drivers often don’t experience any symptoms aside from those associated with the failsafe mode. This typically indicates a wiring issue. Re-check all the wiring around the TPS. If you can’t identify the specific problem, you may want to replace the entire harness.

Common Mistakes To Avoid While Diagnosing The P0122 Code

Many inexperienced mechanics simply replace the throttle position sensor before they’ve verified this is the problem. Make sure you thoroughly inspect all the wires and connectors around the sensor before you replace any components. This will ensure you fix the entire problem.

How to fix the P0122 code

Tips To Avoid P0122 In The Future

This code most commonly triggers after the throttle position sensor is replaced or adjusted due to incorrect installation. Make sure you’re careful to install any new components correctly. This includes checking that all wires and connections are secure. The wires of the throttle position sensor can be damaged by rubbing against the wiring harness. Double-check the placement of the wires every time you install, replace, or adjust the sensor. Damaged wires are one of the main causes of TPS trouble codes, including P0122.

The P0171 code generally tells you too much air is getting into your engine. While this fault code isn’t severe on its own, it can lead to further damage that is more serious.

Let’s take a quick look at a brief of the P0171 code below.

P0171 Definition: System Too Lean (Bank 1)
Code type: Generic – P0171 indicates the same problem whether you’re having a Chevy, Ford, or Toyota, etc.
Can I drive with the P0171 code? Yes, but you should not drive your vehicle for a long time.
Is it easy to fix? Intermediate level.
Cost: $10 – $200 (common)

To help you fully understand the P0171 code and find the right fix, I divided the article into 4 parts.

Click on the images below to jump right into it!

What Does The P0171 Code Mean?

Diagnostic trouble code (DTC) P0171 stands for “System Too Lean” (Bank 1). The air-fuel mixture with too much air and little gasoline could trigger this trouble code.

Lean Mixture = Too much air, not enough fuel

Further Explanation

In normal conditions, the combustion engine operates effectively with an air-fuel ratio of 14.7:1. Specifically, every 14.7 grams of air combines with 1 gram of fuel.

In case Bank 1 receives too much air or/and too little fuel, the engine would be running lean. A vacuum leak or faulty fuel system can be the problem for this.

P0171 Causes Identification: Quick View

Usually, your scan tool throws P0171 with other codes.

This could be a bit challenging to determine the cause. So, I compiled this table to make it easier for you to diagnose the problems and fix them.

Codes Combination	Causes	Solutions
P0171 + P0174 (+P0106)	Loose or faulty gas cap. Vacuum leak.	Tighten or replace the gas cap. Fix the vacuum leak.
P0171 + P0130 to P0135 (+P0300)	Lazy upstream oxygen sensor.	Replace the oxygen sensor.
P0171 + P0100 to P0104	Faulty MAF/MAP sensor.	Clean or replace the MAF/MAP sensor.
P0171 + P0174 (+P0087/P0089)	Bad fuel pressure regulator. Bad fuel pump. Clogged fuel filter. Leak fuel line.	Replace the fuel pressure regulator. Replace the fuel pump. Replace the fuel filter. Replace the fuel line.
P0171 + Misfire codes (P0301 to P0312)	Clogged fuel injector.	Clean the fuel injector.
P0171 + P0600 to P0610	Bad powertrain control module.	Replace the powertrain control module.

Note: The causes for each code combination are the most common ones. There can be some uncommon issues hidden under those codes

P0171: Causes, Symptoms, and How To Fix

Did you find your problem? To further ensure that you actually find the right one, you need to match your car’s symptoms with the cause.

If you don’t want to be a part changer, read on and understand your problem from the inside!

Cause #1: Loose Or Faulty Gas Cap

Checking the gas cap is the very first thing you need to do.

A loose or faulty gas cap will mess up the fuel system, leading to check engine light on and the lean conditions codes popping up.

Make sure the gas cap is not the problem, and you can move on to further diagnosis.

Cause #2: Vacuum Leak

A leak in the air intake system allows air to enter the combustion chamber without the car computer knowing that.

As a result, the amount of fuel that needs to be injected into the engine could be miscalculated by the PCM.

This leads to too much air in the air-fuel mixture.

Try to find and fix it with this video.

Symptoms of vacuum leak:

P0171 arises with P0174 (sometimes with P0106)
Hissing sound
Check Engine Light on
Rough idle
Car stalling
Long-term fuel trim (LTFT) > 10% (check-in “Live data” category)

A smoke test to locate the leak is the first thing you need to do.

Cracked hoses or loosened clamps are usually the reasons for vacuum leaks. In those cases, replacing the hose or tightening the clamp should fix the problem.

Cause #3: Lazy Upstream Oxygen Sensor

The upstream oxygen sensor helps adjust the air and fuel ratio in the engine to its PCM.

The oxygen sensor may be “lazy” because it’s old or dirty, leading to an incorrect air-fuel ratio.

Symptoms of a bad upstream O2 sensor:

A combination between P0171 and faulty oxygen sensor codes (P0130 to P0135) or in some rare cases, P0300 appears
Check engine light on
Bad fuel economy

To make sure your upstream O2 sensor is bad, check the voltage chart on your bank 1 upstream sensor (using the “Live Data” function in your scan tool).

If the value is constantly higher than 0.45v, that’s the wrong data telling the PCM to reduce the fuel (while it’s not supposed to).

bad o2 sensor — This is a typical voltage chart of a “lazy” O2 sensor. The amplitude is smaller and the red line fluctuates above 0.45v.

In this case, replace the O2 sensor.

Here’s how you can do it.

Cause #4: Faulty MAF/MAP Sensor

The PCM uses the Mass Airflow (MAF)/ Manifold Absolute Pressure (MAP) data to adjust the air-fuel ratio.

Therefore, when the MAF/ MAP sensor fails, the ratio is off. Then, the combination between P0171 and P0100 to P0104 will appear.

Symptoms of a faulty MAF/ MAP sensor:

P0171 and faulty MAF/ MAP sensor codes (P0100 to P0104) activate
Check engine light on
Engine stalling, rough idle, misfires
Bad fuel economy

Clean or replace your MAF/ MAP sensor when you find out it has the issue.

Installing the new MAF/ MAP sensor is straightforward so you can do it by yourself.

Watch this video to know how to replace the MAF sensor.

Cause #5: Fuel Pressure Too Low

When the fuel pressure gets low (<55psi), less fuel is injected into the combustion chamber. This problem always leads to lean conditions.

The fuel requires a certain amount of pressure to get into the engine (55psi as common). When the fuel pressure gets low, less fuel is injected into the combustion chamber.

This problem always leads to lean conditions in both bank 1 and bank 2. Therefore, you will get P0171 and P0174 at the same time.

There are several reasons for low fuel pressure:

Bad fuel pump: once the pump is defective, it can not create enough pressure for the whole fuel system.
Clogged fuel filter: limit fuel flow in the system
Bad fuel pressure regulator (FPR): if this component goes faulty, the fuel goes back to the fuel tank without any obstacles, leading to the fuel pressure decreasing.
Leak fuel line: if there is a fuel leak in the fuel line, you’ll start smelling a strong fuel odor, or your car may experience a stall because of a fuel shortage.

Symptoms of bad fuel pressure:

A combination between P0171 and P0174 (sometimes P0087/P0089) appears
Hard starting
Poor performance
Engine stalling
Poor throttle response
Fuel smell (in case of external leak fuel line)

Several things could be causing the low fuel pressure. So you have to diagnose first to detect which is the cause of this problem. Then find the solution for each cause.

Here are the solutions to fix the poor fuel pressure: replace the fuel pressure regulator, the fuel pump, the fuel filter, or the fuel line.

Cause #6: Clogged Fuel Injector

If your fuel injectors are clogged, they will prevent fuel from flowing through them. Then, the amount of fuel in the engine will reduce.

You need to maintain the fuel injectors regularly. If not, the fuel injectors can become clogged, resulting in the P0171 code being triggered with misfire codes (P0301 to P0312).

Therefore, you need to look out for signs of a bad fuel injector and fix it by cleaning the fuel injector.

Symptoms of clogged fuel injector:

P0171 combines with misfire codes (P0301 to P0312)
Misfires
Rough idle and engine stalls
Bad fuel economy

Here’s the way to clean the clogged fuel injector.

Cause #7: Bad Powertrain Control Module

The PCM has the function of calculating the exact amount of fuel added to the air-fuel ratio when air enters the engine. The engine computer uses data from different engine sensors to adjust the air-fuel ratio.

When the PCM is defective, it has a tendency to incorrectly miscalculate the fuel that needs to be injected into the combustion chamber.

So when the PCM fails, it won’t be able to calculate the ratio correctly, leading to the P0171 code being activated with P0600 to P0610.

Symptoms of a bad PCM:

The combination between P0171 and P0600 to P0610 appears
Check engine light on
Car won’t start
Bad fuel economy
Emissions test failure
Engine stalls

The faulty PCM is a rare situation causing the P0171. Fixing the PCM is expensive, complicated, and we don’t recommend replacing it yourself.

How Much Does It Cost To Fix The Code P0171?

The common fixing cost of the P0171 code can be $10 or $200, based on the components that need to be replaced and the labor cost in case you cannot DIY.

A vacuum leak is one of the common causes of the P0171, and the cost to replace it is $10 – $200.

P0131 – O2 Sensor Circuit Low Voltage

The P0131 code triggers when the voltage output of your upstream bank 1 oxygen sensor is too low. Your engine computer uses this sensor to control the air to fuel ratio. Since maintaining the correct rate is key to proper engine operation, you should note when this trouble code activates.

Fixing the P0131 OBD2 code may require replacing the oxygen sensor, but damaged wires and hoses can also cause it. A thorough diagnosis is essential to find and address the true root of the problem. Read on below for more details about this code and what to do if it’s active.

P0131 Code Definition (Generic)

Oxygen O2 sensor circuit low voltage (Bank 1, Sensor 1)

If you want to learn about the P0131 OBD2 code, this is the right place

What Does P0131 Mean?

The oxygen sensors in your engine are how the power control module (PCM) or engine control module (ECM) monitors the air-to-fuel ratio in your exhaust. Comparing this data with the air outside the engine can determine when to inject more fuel or open the system to allow more air to enter.

There are two oxygen sensors in the vehicle. The upstream oxygen sensor, called sensor 1, is positioned before the catalytic converter. It is different from the downstream oxygen sensor, called sensor 2, which measures the air coming out of the catalytic converter.

The P0131 trouble code triggers when the ECM or PCM detects a low voltage from the upstream oxygen sensor. Usually, the voltage must be below the threshold for a certain length of time before the code will trigger. Typically this is two minutes, but it can vary depending on your vehicle.

While P0131 is a generic trouble code, applying to all OBD2 vehicles, the specific fixes can vary depending on your make and model. It’s always a good idea to consult your manual and check for any technical service bulletins before beginning your diagnosis and repair.

Other diagnostic trouble codes related to the oxygen sensors include P0136 and P0137. These codes also warn of a low oxygen sensor voltage, although for a different sensor.

What Are The Symptoms Of The P0131 Code?

In some cases, there are no drivability issues with the P0131 trouble code. This case is relatively rare, however. Typically, you’ll experience one or more of the following symptoms:

Activation of the check engine light
Smoke in the exhaust
Bad smell from the exhaust
Rough running engine
Reduced fuel economy
Stalling engine

What Are The Causes Of P0131?

Faulty or damaged oxygen sensor heating circuit
Defective oxygen sensor
Faulty or damaged wiring around the oxygen sensor
Shorts, open, or high resistance in the oxygen sensor signal circuit
Leaks in the vacuum system
Fuel pressure too low or too high
ECM or PCM software requires an update
Faulty ECM or PCM (not as common)

How Serious Is The P0131 Code?

While the severity of the P0131 code can vary, it can be of high severity. Therefore, you should stop driving your vehicle as soon as possible and identify the root of the problem. Failure to do so could lead to more serious engine damage.

How To Diagnose And Fix The P0131 Code?

Digital multimeter is one of the tools which can diagnose the error P0131 code.

Tools you’ll need:

Use an OBD2 scan tool to check for other trouble codes, then clear codes and test drive your vehicle to see if the code recurs. In some cases, P0131 is an intermittent problem. Especially if you haven’t experienced any drivability symptoms, the code may clear without issue.
Read the freeze frame data for oxygen sensor 1. Pay attention to the miles per hour (MPH), revolutions per minute (RPM), and load readings. Also, read the engine temperature sensor readings and the oxygen sensor 2 readings to look for any inconsistencies.
Visually inspect the wiring around the oxygen sensor. Replace any wires that are damaged or corroded, and check the connectors for damage, as well. Ensure all the wires are firmly connected and clear of any other engine components that could cause future damage.
Inspect the wiring harness. Perform a wiggle test to make sure it’s not chafing or grounding.
Check the vacuum hoses around the bank 1 upstream oxygen sensor for leaks. Make sure to feel along with hidden areas of the hoses for damaged or weak spots you can’t see. Pay close attention to the ends of the hoses, as well, making sure there’s no fraying or damage and that all hoses are secured tightly.
Use a digital multimeter to check the voltage output of oxygen sensor 1 on bank 1. Your vehicle’s manual can tell you what the voltage reading should be. If it’s giving a null or infinite reading, you likely have an open or short in the oxygen sensor. Any variance from the designated range is a sign your oxygen sensor probably needs to be replaced.
Check the signal wire at the PCM or ECM using the digital multimeter. Check for shorts and open circuits, and replace the connector or wire as necessary.
If the code still doesn’t clear, you may need a software update or have a more significant electrical issue. In either case, your best option is to take your vehicle to a professional mechanic for further diagnosis.

Common Mistakes To Avoid While Diagnosing The P0131 Code

Many people replace the oxygen sensor before they search for other potential causes for the trouble code. While a defective oxygen sensor may be the issue, make sure you check for wiring issues and vacuum leaks, as well. These are equally likely to trigger the P0131 trouble code.

Tips To Avoid P0131 In The Future

Two potential causes of the P0131 trouble code are damaged or loosened wires and vacuum leaks in the exhaust system. You can avoid both through preventative maintenance. Consider applying an anti-corrosive treatment to your engine. Also, be careful when installing hoses and wires. Make sure they’re firmly connected and that they’re not rubbing engine components that could damage them.

P0137: O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2)

Concerned about the P0137 code popping up and not sure what it means?

Let’s give you a quick rundown of what to expect.

P0137 Definition: Oxygen Sensor Circuit Low Voltage (Bank 1, Sensor 2.)
Code type: Generic – P0137 indicates the same problem whether you’re having a Chevy, Toyota, or Honda, etc.
Can I drive with the P0137 code? Yes, in the short run. However, extended driving periods may cause engine damage.
Easy to fix? Beginner to intermediate level.
Cost: $20 – $95 (common.)

In this article, I will go over what the code means, possible causes, solutions, and repair costs.

Let’s get started!

What Does The P0137 Code Mean?

The P0137 is triggered when the downstream O2 sensor (bank 1) voltage is lower than 0.21V for longer than 2 minutes. In many cases, it can be because your downstream O2 sensor is faulty.

Downstream oxygen sensors (located after the catalytic converter) monitor the conditions of the catalytic converter.

The more air in the exhaust gas (after passing the cats), the lower the downstream O2 sensor’s output voltage.

Because the catalytic converter already processed the exhaust gas, the oxygen level is stable. Therefore, a normal working downstream O2 sensor stays around 0.45 volts.

For some reason, the sensor may detect an abnormally high percentage of oxygen in the exhaust gas (or it thinks so.) This leads to a drop in the sensor’s voltage. And when it’s below 0.21v, P0137 is set.

P0137 Causes Identification: Quick View

The most common cause of P0137 is a faulty downstream oxygen sensor. However, there may be other reasons.

To make the information more digestible, here is a table with the code combinations, their causes, and solutions.

Codes combinations	Causes	Solution
P0137 only (no symptom); P0137 + P0420	Bad downstream O2 sensor Faulty O2 sensor’s circuit	Replace downstream O2 sensor Fix the short or open circuit
P0137 + noisy exhaust	Exhaust leak near downstream O2 sensor	Apply epoxy bond (small leak)/welding (large leak)
P0137 + P0141	Bad downstream O2 sensor	Replace downstream O2 sensor
P0137 + P0171; P0137 + P0157	Vacuum leak Lazy upstream O2 sensor	Smoke test & Seal vacuum leak Replace upstream O2 sensor
P0137 + P0138	Bad PCM	Replace PCM

Note: The causes for each code combination are the most common ones. There can be some uncommon issues hidden under those codes.

P0137 Causes, Symptoms, and How to fix

Depending on the underlying problem, there may be different symptoms to look out for.

However, there is one common symptom that remains the same, and that is an illuminated check engine light.

Let’s explore the different causes of the P0137 error code and any unique symptoms you may experience.

Causes #1: Bad Downstream O2 Sensor

A faulty downstream O2 sensor would report false info to the PCM, which would think there is something wrong with the catalytic converter.

If this is the case, P0137 may appear alone or come with other codes like P0420, and P0141.

A bad downstream O2 sensor does not result in any symptoms with your car’s performance. This is because downstream sensors are not used to adjust the air-fuel ratio (like upstream.)

Check the O2 sensor with a multimeter. If this fails, replace it.

Causes #2: Short Or Open In Downstream O2 Sensor Wiring

Sometimes, the problem is not the downstream sensor itself.

After making sure the O2 sensor is ok, check its wiring harness for any short, high resistant, or open.

Again, this cause will not lead to any symptoms.

Causes #3: Exhaust Leak Near Downstream O2 Sensor

When the exhaust gas is pushed out of the system, it forms a pulse. The front end of the pulse has a high pressure while the negative pressure is behind.

When there is a leak, some of the gas in the front end of the pulse escapes. However, the low pressure at the end of the pulse sucks the air in.

The changes in the exhaust gases cause an inaccurate reading on the downstream O2 sensor.

The most obvious symptom of an exhaust leak is the buzz or hum sounds when the engine is running. You can rev the car intermittently to hear the sound more clearly.

After finding the leak, you would need to repair it by applying epoxy to seal a small leak or performing welding for a larger one.

Causes #4: Lean Condition (Bank 1)

If your engine is running lean (too much air), the exhaust gas will contain more oxygen than usual. When the catalytic can not handle all of this, some of the oxygen is still left in the exhaust gas after passing the cats.

As mentioned above, an abnormally high percentage of air will decrease downstream O2 sensors voltage, triggering P0137.

There are many reasons for the lean condition. However, vacuum leaks and lazy upstream O2 sensors (in this case, the bank 1 sensor) are the most common causes.

Vacuum leak symptoms:

Hissing sounds
Rough idle
Often stalls when stopping
Long-term fuel trim (ltft1)>10%

Lazy upstream O2 sensors symptom:

The sensor’s output voltage slightly fluctuates above .45v (below image)

First, conduct a smoke test to make sure there is no leak in the intake system.

If there are no leaks, then the problem could be in the upstream O2 sensor. Replacing it with a new one should fix the issue.

Causes #5: Bad PCM (Rare)

Bad PCM is a rare case and it should be your last conclusion.

If your car throws a combination of P0137 and the P0138 (low voltage and high voltage on one downstream O2 sensor,) this can be the cause.

Depending on the make and model, the replacement costs of a PCM may vary. But it will not be cheap!

I suggest heading to a local mechanic for replacing the PCM as it’s a complicated process.

How Much Does It Cost To Fix The Code P0137?

The most common solution to the P0137 error code is replacing the downstream O2 sensor, which can cost between $20 and $95.

The table below will help break down repair costs (DIY and mechanic) according to the different solutions.

The Estimated Repair Cost Of P0137

Solutions	Repair cost
Replace O2 sensor	DIY: $20 – $95 Mechanic: $100 – $450
Repair O2 sensor circuit	DIY: $10 – $20 Mechanic: $130 – $140
Repair exhaust leak	DIY: $20- $50 Mechanic: $130 – $190
Replace PCM	DIY: Not recommended Mechanic: $1,000 to $3,000

Note: The data in this table is collected in May 2022. The actual price depends on many factors, such as your car’s make and year, mechanic’s rate, time, market price, etc.

P0013 – “B” Camshaft Position – Actuator Circuit/Open

The P0013 code relates to your engine’s variable valve timing (VVT) system, a crucial system found in all modern vehicles. Its primary purpose is to alter your camshaft’s speed to give you the right power your engine needs.

Your engine won’t always manifest symptoms when something goes wrong in the VVT system, but this doesn’t mean it can be taken lightly. Issues with your engine’s timing can lead to potentially significant engine damage, including damage to your ECM.

Luckily, the fix for P0013 is often a relatively easy and affordable one. Something as simple as a loose wire can be the culprit in many cases. It’s also one of the codes you’re likely to see if you’ve neglected your regular oil change.

Isolating the problem is often a relatively quick and easy process if you know the right steps to follow. Read the information below to learn more about this code and how you can fix it.

P0013 Code Definition

P0013 Code Definition (Generic): “B” Camshaft Position Actuator Circuit (Bank 1)

If you want to learn about the P0013 OBD2 code, this is the right place

What Does P0013 Mean?

Modern engines don’t run at the same speed all the time. Instead, they use a variable timing system, adjusting the valve timing based on the sensors’ signals. This feature makes the engine’s operation more efficient, improves performance, and gives you better fuel efficiency.

When the engine control module (ECM) needs to adjust the camshaft’s timing, it does so through the camshaft position actuator. If the RPM (revolutions per minute) of the camshaft doesn’t change in response, the P0013 trouble code is activated.

Specifically, two main conditions will trigger the P0013 code. The first is when the ECM reduces the camshaft’s speed, but the oil control valve (OCV) output remains 100%. The second is when the ECM increases the camshaft’s speed, but the OCV output is 2% or less.

There are two circuits connected to the camshaft position (CMP) actuator. The high control circuit sends a 12-volt signal to the actuator, while the low reference circuit serves as a return circuit. Issues with either of these can lead to the activation of the P0013 code, as can wiring problems elsewhere in your timing system.

While P0013 is a generic code, it is only found in vehicles that use variable valve timing, including most vehicles made in the past decade, regardless of manufacturer. Exactly where you find the CMP actuator will vary depending on your engine, but the P0013 trouble code will always point you to bank 1. This is the side of the engine that contains cylinder 1.

What Are The Symptoms Of The P0013 Code?

The P0013 trouble code symptoms vary depending on what position the camshaft is in when the problem starts. Potential symptoms include:

Activation of the check engine light
Hard starts
Reduced gas mileage
Rough running
Reduced engine performance
Engine hesitation and stalls

What Are The Causes Of P0013?

The P0013 code relates to the variable valve timing (VVT) system

Faulty VVT actuator
Damaged or loose wires around the VVT system
Open or short in the VVT system
Faulty oil control valve
Faulty or damaged ECM

How Serious Is The P0013 Code?

The P0013 code is of moderate severity. Driving with this trouble code active for an extended time can cause damage to your ECM. Even if you’re not experiencing significant drivability issues, you should repair the issue as soon as possible to avoid further problems.

How To Diagnose And Fix The P0013 Code

While this is a generic powertrain code, the specific fix may differ depending on your car. Check for any specific repair steps in your vehicle’s manual before beginning the generic diagnosis and repair steps below.

Tools You’ll Need:

Method:

Scan your vehicle using an OBD2 scanner. Check the freeze frame data and the conditions present when the code was set. Also, check if any other trouble codes are present. You may see other powertrain-related codes, such as P0011, P0012, or P0020-P0022.
Visually inspect all the wires around the VVT system. Replace any that are damaged or broken due to corrosion, and ensure that all wires are securely connected.
Check the level and quality of your oil. Make sure the oil level is correct. Also, check the viscosity and quality of the oil. If it’s old or dirty, drain the oil, replace your oil filter, and refill your system with new oil.
Clear the codes and test drive your vehicle, replicating the conditions under which the code was first set. If the code comes back, continue with your diagnosis.
If the OCV is stuck open, this is often the result of an internal short. You can find out if this is the case using a digital multimeter. Measure the resistance of the terminals of the camshaft oil control valve. It should measure somewhere between 6.9 and 7.9 ohms. Your vehicle’s manual will tell you the specific reading. If they don’t match, replace the OCV.
Remove the connectors on the oil control valve. Use a multimeter to test the wires. If you get a null or infinite reading, there is an open circuit or a short. Replace the wire.
If the code still doesn’t clear, you may have a more serious electrical problem. Take your vehicle to a mechanic for further diagnosis.

Common Mistakes To Avoid While Diagnosing The P0013 Code

Many mechanics fail to do a visual inspection of the VVT system, assuming the problem is with the valve or circuit. Make sure you conduct a thorough diagnosis before replacing any components. The issue might be a simple and affordable one to repair.

Troubleshooting the P0013 code

Tips To Avoid P0013 In The Future

Preventative maintenance is the best way to stave off the P0013 trouble code. Make sure your oil is always filled to the proper level and changed when needed. Visually inspecting the wires of your system for frays and loose connections can also prevent P0013 and other trouble codes related to the variable valve timing system.

Definition: EVAP System Purge Flow Malfunction
Severity: Medium
DIY Skill Level: Intermediate
Continue To Drive?: Yes (Short term)
Estimated Repair Cost: $50 – $500

What Does The P145C Honda Code Mean?

The P145C trouble code is a manufacturer-specific code. It is titled as an “EVAP System Purge Flow Malfunction” or “Fuel Tank Pressure Sensor Range/Performance Problem” by the Honda car manufacturer.

This code is triggered when the car’s Powertrain Control Module (PCM) detects a malfunction within the EVAP system of your Honda. In most cases, the culprit is likely the wrong fuel tank pressure sensor readings.

The P145C code in Honda usually comes with P0497 or P0496, indicating the problem within the EVAP system.

P0172: System Too Rich (Bank 1)

Was the P0172 code activated on your scan tool? Do you wonder whether it is dangerous to keep driving?

Read on to have a first evaluation of your situation!

P0172 Definition: System Too Rich (Bank 1)
Code Type: Generic – P0172 indicates the same problem whether you’re having a Chevy, Honda, or Toyota, etc.
Can I drive with the P0172 code? Yes, but you should drive for a short period. Extending driving will cause more severe damage to your engine.
Easy to fix? Beginner-Intermediate level.
Cost: $30 – $280 (common)

Now, you know this code is not that dangerous.

If you don’t want to waste your money, let’s dive into 7 causes that might trigger the P0172 code and the corresponding solutions.

What Does The P0172 Code Mean?

P0172 is an OBD-II generic code triggered when the engine control unit (ECU) detects too much gasoline and not enough oxygen in the air-fuel mixture.

Further Explanation

The ECU monitors the engine’s air-fuel ratio through mass airflow sensor (MAF), oxygen sensors, and manifold absolute pressure (MAP).

The ideal air-fuel mixture (air-fuel ratio) is always following the rate of 14.7:1; 14.7 grams of air are required for every 1 gram of fuel. This specific ratio was chosen because of its highest power output but lowest fuel consumption rate.

When the air-fuel ratio goes below 14.7, the amount of fuel in the combustion chamber is much more than the oxygen.

This is called a “rich” mixture, and then the ECU triggers the P0172 code.

P0172 Causes Identification: Quick View

When your scanner tool displays the P0172 code, sometimes the screen will show another code following P0172.

Here is a detailed table helping you identify which one is the culprit and find out the solutions immediately.

Codes Combination	Causes	Solutions
P0172 + P0101 /P0100/P0102	Dirty, obstructed, or faulty MAF/MAP sensor.	Clean or replace the MAF/MAP sensor.
P0172 + P0089	Failed fuel pressure regulator.	Replace the fuel pressure regulator.
P0172 + P0130-P0135	Faulty oxygen sensor.	Replace the oxygen sensor.
P0172 + P0402	Stuck-open exhaust gas recirculation (EGR) valve.	Replace (preferred) the EGR valve.
P0172 + P0116/P0117/P0118	Bad coolant temperature sensor.	Replace the coolant temperature sensor.
P0172 + P0128	Stuck-open thermostat.	Replace the thermostat.
P0172 + Fuel odor, Hard starts, Increased fuel consumption	Leaking fuel injectors.	Replace the injector filter. Replace the O-ring. Replace the fuel injector.

Note: The causes for each code combination are the most common ones. There can be some uncommon issues hidden under those codes.

P0172: Causes, Symptoms, And How To Fix

Cause #1: Faulty MAF/MAP Sensor

The mass airflow (MAF) and manifold absolute pressure (MAP) sensor are essential to your car’s electronic fuel injection system.

Their function is to help the PCM determine the required fuel delivery for a perfect rate of 14.7:1.

You can find them near the engine’s intake manifold.

Over time, the MAF/MAP sensor can be contaminated for many reasons, such as dirt, air, and debris in the sensor.

That’s why they failed, leading to overstating the number of air flowing into the engine.

Hence, drivers should pay attention to any of the following symptoms in their vehicle’s performance:

P0172 and P0101/P0100/P0102 code activated.
Check engine light on.
Black exhaust smoke.
Rough idle.
Poor fuel economy.
Poor acceleration.

You can easily fix the P0172 code by cleaning the dirty MAF/MAP sensor or replacing it if the MAF/MAP sensor is faulty.

I watched a lot of videos on how to clean a MAF/MAP sensor and this 10-minute video from ChrisFix is the most easy-to-follow. Check it if you want to clean it yourself.

Cause #2: Faulty Fuel Pressure Regulator

A fuel pressure regulator regulates the fuel pressure (35-65 psi) going to the fuel injectors.

Suitable fuel pressure (air to fuel ratio) helps your vehicle run with maximized power and fuel economy. If the fuel regulator goes wrong, the fuel pressure is too high, resulting in a rich air-fuel ratio.

A ruptured diaphragm inside the regulator and a stuck closed regulator are two reasons causing a rich running condition.

If you notice these symptoms, your vehicle may have a bad fuel pressure regulator:

A combination of P0172 and P0089 codes appeared.
Poor engine performance.
A fuel leak in the regulator’s vacuum line.
Black smoke.
Soot on spark plugs.

Replacing the fuel pressure regulator with a new one will solve this problem.

Cause #3: Faulty Oxygen Sensor

An oxygen sensor (upstream) is a device used to help the engine keep a specific air-fuel ratio that balances power, fuel economy, and emissions.

When the O2 sensor is defective, it might detect the wrong amount of air and send it back to the ECU, making the air-fuel ratio not follow the standard rate.

If you don’t want more damage to your car, take a look at these signs:

P0172 and faulty O2 sensor codes (P0130-P0135) appeared.
Check engine light on.
Poor fuel efficiency.
Smell and black smoke from the exhaust.
“Lazy” O2 sensor voltage chart.

“Lazy” O2 Sensor Voltage Chart

When the O2 sensor voltage reaches 0.6v, the PCM reduces the fuel. Otherwise, when the value drops below 0.3v, the PCM raises the fuel. The red line should fluctuate in this range continuously.

The red line fluctuates below 0.45v. It sends the “fake” lean signal to ECU, making the system rich.

Replacing a faulty oxygen sensor is an effective way to fix the P0172 code if it is the problem.

Cause #4: Stuck-Open EGR Valve

Exhaust Gas Recirculation (EGR) is a system used for reducing automotive nitrogen oxide (NOx) emissions.

It works by taking a small quantity of the exhaust gas back to the engine’s combustion chambers through the intake manifold.

After a long time, carbon deposits build-up inside the EGR valve, sticking it open.

The endless exhaust gas takes the air’s place, making the amount of air decrease dramatically. Consequently, the air-fuel ratio is not balanced anymore.

Stuck-open EGR will bring you a lot of bad situations, and you should look for these signs to clean or replace the EGR valve as soon as possible:

P0172 and P0402 code triggered.
Poor performance.
Rough idle.
Increased fuel consumption.
Smell of exhaust gas.
Engine knock.
More emissions.

With a stuck-open EGR valve, it is recommended to replace it as the EGR valve is not too pricey.

If you have a low budget, try to clean the build-up inside with this video.

Another video from ChrisFix on how to clean and replace an EGR valve. Watch this simple guide to save your time and money.

Cause #5: Bad Coolant Temperature Sensor

As evident from its name, an engine coolant temperature sensor (ECT) measures the engine coolant’s temperature.

An inaccurate coolant temperature can cause a rich condition because they will report that the engine is still cold, which will cause the PCM to keep the mixture rich long after the engine is at proper operating temperature.

Here are some significant symptoms of a faulty coolant temperature sensor:

P0172 and P0116/P0117/P0118 codes activated.
Check engine light on.
Overheated engine.
Poor fuel efficiency.
Poor engine performance.
Black smoke from the exhaust pipe.

In addition to these symptoms, you can take a small test to compare the coolant temperature with a thermal gun and the ECT’s temperature in the Live Data function. If the number on the thermal gun is different from the one on the scan tool (>190ºF), maybe your ECT sensor is broken down.

A coolant temperature sensor is not too expensive, you can erase this code from your car by replacing the ECT sensor.

An easy-to-follow video from Mikes House of Mods for anyone who wants to change the ECT sensor at home. If you are an auto DIYer, don’t ignore this!

Cause #6: Stuck-Open Thermostat

When the thermostat is closed, the flowing of coolant is blocked, making the engine run hot to crank.

If the thermostat is in an open position, the coolant will constantly flow into the radiator, making the engine run cold.

The engine thermostat is a valve that can open and close to let the coolant flow into the radiator, lowering the engine’s temperature.

A stuck-open thermostat can make your engine still cold and take more time to warm up. Therefore, your car’s engine may not be likely to reach proper operating temperature and need a richer fuel mixture, leading to more fuel than air.

To avoid any further damage, you should notice these obvious signs:

A combination of P0172 and P0128 pops up.
Long warm-up time.
Lack of heat.
Poor gas mileage.

It’s not easy to unstick the stuck-open thermostat as it seems. I suggest you should replace the thermostat with a new one since it’s inexpensive.

Cause #7: Leaking Fuel Injectors

Fuel injectors spray the fuel as mist into a car’s engine through a small nozzle.

Leaking fuel injectors appeared in older cars with high mileage. A fuel injector can leak due to two primary causes:

The body of the injector

The O-ring

When the fuel injector leaks, it will spray excess fuel in liquid form, not mist. Keeping the fuel injector leaking constantly will create a rich air-fuel mixture.

Be careful with these symptoms if they appear on your car:

Hard starts.
Fuel odor.
Hesitation or shaking while idling.
Increased fuel consumption.
Increased exhaust.
Thinning oil.
Hydrolocking.

There are three ways you can use to fix the leaking fuel injectors, you can replace the injector filter, the injector O-ring, or the fuel injector itself.

P0171: System Too Lean (Bank 1)

P0121 – Throttle/Pedal position sensor/switch “A” circuit

The P0121 code triggers when the “A” and “B” circuits of your vehicle’s throttle position sensor don’t match, which can be a severe problem, activating your car’s failsafe mode and limiting engine performance.

While the throttle position sensor failures are the most common cause of the P0121 trouble code, you don’t want to replace it. There may be issues with the wiring or more extensive electrical problems. Conducting a full diagnosis is essential to make sure the code doesn’t return.

In many cases, the P0121 trouble code can be quickly cleared in a home garage. Read on below to learn more about what causes it and how you can identify and eliminate the problem.

P0121 code definition

P0121 code definition (generic): Throttle position sensor/switch A circuit range/performance problem

P0121 Dodge code definition: Throttle Pos. Exceed (Short Time)

P0121 Ford code definition: (TP) sensor circuit performance problem

P0121 Nissan code definition: (TP) sensor circuit performance problem

P0121 Toyota code definition: Throttle Pedal Position Sensor/Switch “A” Circuit Range/Performance

If you want to learn about the P0121 OBD2 code, this is the right place

What does P0121 mean?

The sensor that monitors your throttle’s movement is the throttle position sensor (TPS). This sensor is a potentiometer, measuring the current that passes through to indicate the throttle position. As the throttle opens, the voltage goes up.

The TPS circuit has a designated output voltage for both the “A” and the “B” circuit. This voltage is monitored by the engine control module (ECM) to make sure the throttle position is staying where it should be. The ECM also sends a 5-volt reference signal to the sensor. Usually, the sensor will measure around .5 volts when idling and as much as 4.5 volts when at full throttle.

The “A” and “B” circuits of the TPS sensor should maintain a particular relationship with each other. When the P0121 OBD2 code triggers, the ECM has detected a TPS “A” circuit voltage that’s either too high or too low compared to the “B” circuit.

P0121 is a generic powertrain code, so it applies to any vehicle equipped with OBD2. You may want to follow different steps for the diagnosis and repair depending on your vehicle manufacturer, however. Check for any technical service bulletins for this code for your vehicle.

What are the symptoms of the P0121 code?

When the P0121 trouble code activates, the engine will go into failsafe mode, limiting the throttle’s response, which prevents your car from driving above a certain speed. In addition to the failsafe mode, you’ll likely notice some of the following symptoms:

Activation of the check engine light
Knocking sounds in the engine
Engine stalling or refusing to start
Vehicle accelerating slowly
Smoke in the exhaust when accelerating
Engine stumbling and jerking when changing speeds
Lower maximum speed

The P0121 code indicates a problem with the throttle position sensor

What are the causes of P0121?

Open or short in TPS
Open or short in the TPS wiring
Faulty or loose connections on the TPS
Corrosion or moisture in sensor connections
Failed or faulty ECM (rare)

How serious is the P0121 code?

The P0121 trouble code is very severe. Only the activation of failsafe mode will make your car difficult to drive. It may also prevent your car from starting or lead to stalling if it does run. You should stop driving your vehicle when this code activates and fix the problem immediately.

How to diagnose and fix the P0121 code

Tools you’ll need:

Use the OBD2 scan tool to diagnose the P0121 code

Method:

Scan the TPS data using an OBD2 scan tool. Compare the readings for circuit “A” and circuit “B.” If there’s a variance, check your manual for manufacturer tests for the TPS.
Scan your system to see if any other trouble codes have been triggered. You may see other codes related to the throttle position sensor (P0120-P0124).
Use the OBD2 scan tool to read the idle and wide-open throttle (WOT) readings. Compare them with the specifications in your vehicle’s manual. If they’re not, this indicates an issue with the TPS, wiring, or connectors.
Visually inspect all the wiring and connections of the TPS system. Replace any wires that are damaged or corroded, and make sure all connections are secure. Also, inspect the TPS connections for corrosion or moisture damage. After your inspection, clear the codes and test drive your vehicle. If the code returns, continue with your diagnosis.
Use an oscilloscope to check for an open or short in the signal sent by the TPS. The signal should go up and down smoothly. If you see sharp drops or spikes, the sensor should be replaced.
Use a digital multimeter to check the reference voltage at the connector. It should read 5 volts. If it doesn’t, check the ground circuit. It may have an open or short. If the signal circuit reads 12 volts, trace the circuit to find the source of the short and repair it.
If the code still doesn’t clear, take your vehicle to a mechanic for further diagnosis. In rare instances, the P0121 triggers because of a more serious electrical problem. A professional will be able to determine if this is the case.

Common mistakes to avoid while diagnosing the P0121 code

Many mechanics immediately replace the TPS before visually inspecting the system for corroded wires, loose connections, and other simple fixes. Make sure you conduct a full, thorough diagnosis before replacing any components. If the wiring is the problem, replacing the sensor won’t fix it.

How to fix the P0121 code

Tips to avoid P0121 in the future

If the TPS wires aren’t installed carefully, they can rub against the wiring harness., which leads to damaged wires, one of the primary causes of the P0121 trouble code. Ensure the wires in your system aren’t touching anything that could damage them to prevent shorts and other electrical issues. Moisture also damages electrical components, like sensors. If you see signs of moisture on the TPS or its connections, figure out how it’s getting into your engine. Identifying and fixing the source of the leak will prevent future damage to the TPS.

If you want to learn about the P0014 OBD2 code, this is the right place

What Does P0014 Mean?

The P0014 OBD2 code indicates that the timing of your exhaust camshaft is too advanced. Your engine doesn’t operate the same way all the time. The engine control unit varies the valves’ timing, pistons, and other components depending on how much the engine is revving. Each component has an associated sensor that sends information to the ECU. The ECU then uses this data to determine when to power certain systems and how much power to send them. The goal is to keep the engine running as smoothly and efficiently as possible, with minimal emissions. If the ECU detects that the B camshaft on bank 1 has advanced more than it should, the P0014 trouble code will activate. Bank 1 is the side of the engine that contains cylinder 1. Depending on your vehicle, the B camshaft could be called the rear camshaft, the right camshaft, or the exhaust camshaft.

What Are The Symptoms Of The P0014 Code?

The symptoms of this code can change based on the position of the camshaft when it became over-advanced. Some common symptoms include:

Activation of the check engine light
Engine is hard to start
Engine idles rough or stalls while idling
Increased fuel consumption
Increase in harmful emissions

What Are The Causes Of P0014 OBD2 Code?

Two systems could be the origin point of P0014: The camshaft and its components or the oil system. Specific causes include:

Failure of camshaft variable timing solenoid
Bad timing in camshaft
Faulty wiring in the intake timing system
Stuck or faulty camshaft phaser
Short in the oil control solenoid
Excessive oil viscosity
Clogged passages around the camshaft phasers

How Serious Is The P0014 OBD2 Code?

The drivability issues associated with P0014 can cause further damage to your engine if allowed to go on for too long. While it is not unsafe to drive with this code active, you should repair it as soon as possible to avoid additional complications.

How To Diagnose The P0014 OBD2 Code

The P0014 code can be diagnosed by an OBD2 scan tool

More often than not, the P0014 OBD2 code results from a mechanical failure in your engine. You should check your vehicle’s manual for suggestions before beginning your diagnosis. This trouble code often has specific fixes depending on what kind of car you drive.

Tools You’ll Need:

An OBD2 scan tool

Method:

Scan your system for other trouble codes. If you detect related trouble codes like P0010, P0011, P0012, P0020, P0021, or P0022, diagnosing those could help you identify the specific problem.
Inspect the wiring and solenoids around the oil control valve and bank 1 B camshaft. Replace any that are frayed or damaged, and ensure all connections are secure.
Check the level and viscosity of your oil. Your vehicle’s manual should contain information on the correct viscosity for your system.
Use an OBD2 scan tool to read the live freeze frame data for the bank 1 B camshaft. Disconnect the oil control valve connected to the camshaft. If the valve is functional, the data should change. If it doesn’t, the valve should be replaced.
Find the cam phaser and inspect it for sludge or damage. Also, inspect the oil passages around the camshaft phasers for build-up.

Common Mistakes To Avoid While Diagnosing The P0014 OBD2 Code

Some people replace their sensors before checking to see if there’s a mechanical problem. P0014 is rarely electrical in nature. Run a full diagnosis before you replace any components.

What Should You Do To Fix The P0014 OBD2 Code?

Use an OBD2 scan tool to clear the trouble codes after each repair, then conduct a test drive to see if they recur. While this might seem tedious, it will prevent you from making unnecessary fixes and is the best way to identify the root cause definitively.

Replace any damaged wires or solenoids found in your diagnosis.
If your oil is old, dirty, or too thick, you should replace it. Drain the oil, then replace the oil filter. If you noticed deposits clogging the oil passages, flush the system before adding new oil.
Replace the cam phaser if it’s dirty or damaged.
Replace the oil control valve if it failed the freeze-frame test in step 4 of the diagnosis.
If none of these fixes clear the code, the problem is likely an electrical malfunction in the engine control unit. Take your vehicle to a mechanic for further diagnosis.

Tips To Avoid P0014 OBD2 Code In The Future

More often than not, this problem is the result of a dirty engine. The best way to avoid problems with your camshaft timing is to prevent sludge and other deposits from accumulating in the first place. You can take a few easy steps to keep your engine clean:

Drive your engine hard. Getting your engine hot is the best way to remove deposits from your system. This naturally happens if you do a lot of fast driving, so engine build-up is more common for cars mostly driven in cities. When your engine starts feeling sluggish, go out on the highway and push your engine harder than usual for a few miles.
Use the right oil. A high-quality oil of the correct viscosity will keep your system running its best.
Replace your oil regularly. The older your oil, the less effective it is at lubricating your system. Any dirt or debris in the oil can also stick to components and clog them. Make sure to change your oil as soon as your car is due.

P2002 – Diesel particulate filter efficiency below threshold

The P2002 code applies to diesel engines. They contain an additional filter to remove soot and contaminants from the exhaust. This limits harmful emissions and allows your vehicle to meet state standards.

The activation of P2002 indicates the inefficient filtering of your exhaust. This problem can be intermittent, and in some cases, will go away on its own with no driver intervention. You shouldn’t ignore it if it does stick around, though, as this affects both the environment and your engine’s performance.

Certain driving conditions and vehicles are more likely to activate the P2002 trouble code than others. Read on below to learn what you should do if this code triggers in your car or truck.

P2002 Code Definition (Generic): Diesel Particulate Filter Efficiency Below Threshold Bank 1

If you want to learn about the P2002 OBD2 code, this is the right place

What does P2002 mean?

This code relates to diesel engines made in 2007 and later. These vehicles use an emission control device to lower the soot content of the exhaust. It does this by heating the engine enough to burn off pollutants, with an additional reductant catalyst to start the process.

The diesel particulate filter (DPF) removes about 98% of the soot in the exhaust when functioning correctly. If the emission control system has been activated, but the particulates in the exhaust don’t burn off, the P2002 trouble code activates.

When the DPF is in operation, it generates backpressure. Pressure feedback sensors allow the engine control module (ECM) or powertrain control module (PCM) to monitor its operation. A discrepancy in the pressure limits indicates there’s an issue with the filter.

While this code is a generic powertrain code, applicable to any diesel engine, the specific fixes can vary depending on your make and model. P2002 is most common in Dodge, Chevy, Ford, and GMC pickups. It can also trigger diesel cars, such as those made by Audi, Lexus, and VW.

This code is similar to P2003. The difference is P2002 relates to bank 1 of your engine, while P2003 points to bank 2. Bank 1 is the side of the engine that contains cylinder 1.

P2002 is what is considered a “soft code.” This means it reports an issue in real-time and can clear itself if the fault is corrected. If this happens once, you don’t need to worry about it. Repeated instances of P2002 warrant diagnosis. You should also consider repairs if the code does not turn itself off after a completed drive cycle.

What are the symptoms of the P2002 code?

The check engine light may stay illuminated with P2002, or it may come on intermittently. In many cases, there are no drivability issues associated with this code. If there are symptoms, they include:

The activation of the check engine light
Reduced fuel economy
Sluggish acceleration
Diluted oil

What are the causes of P2002?

Fouled or faulty DPF.
The exhaust back pressure sensor is faulty.
Leaks in the exhaust system.
Fuel quality is too low for the engine.
The engine is not reaching high enough speeds/temperatures.
Aftermarket components are not suitable for vehicles.
The air cleaner element is dirty.
Faulty PCM/ECM or components.

How serious is the P2002 code?

The P2002 trouble code is moderately severe. Although you may not experience drivability issues, your engine may go into failsafe mode if you don’t clear the code. Because of this, it’s essential to find the source of the issue as soon as possible.

How to diagnose and fix the P2002 code

Tools you’ll need: OBD2 scan tool

Use an OBD2 scan tool to read the codes. If other codes are present, fix those first.
If you mostly drive in a city or at low speeds, your engine may not be reaching high enough temperatures to burn off the soot. Take your car for a hard drive. Ensure you get at least 55 miles per hour for 20-30 minutes, then reduce speed quickly. Clear the codes and rescan with the OBD2 scan tool.
If you have recently modified your vehicle, replace it with the original part. Certain modifications, including cat-back exhaust kits or cold air intake kits, can trigger this code. You can also check with the manufacturer to see if this is a known issue for your vehicle.
Check for loose connections around the bank 1 DPF. Also, check for any burnt or loose wires, and make sure there’s no corrosion on the connectors.
Look for exhaust leaks around the DPF. Pay close attention to the ends and connections, making sure everything is connected securely.
Verify that you’re using fuel that is the correct quality for your engine. The fuel that contains too much sulfur leads to clogs in the DPF. Consult your manual if you’re not sure what the ideal diesel quality is for your engine.
Check the DPF for dirt and clogs. In some cases, these filters may become too fouled to clear with a hard drive. Replace the filter, then clear the codes and test drive your vehicle.
Should the code still not clear, take your car to a mechanic for further diagnosis. Advanced scan tools like the Tech II can determine if there is an issue with the ECM or PCM.

The way to fix the p2002 code

Common mistakes to avoid while diagnosing the P2002 code

If the issue causing the P2002 trouble code is a fouled filter, it may be a temporary problem. Make sure you take a test drive, reaching at least 55 miles per hour before replacing any components. DPF filters generally last a long time, so don’t assume the filter is failing until you’ve checked for other issues.

Tips to avoid P2002 in the future

Wires touching the DPF can be burnt and damaged by the high temperatures generated. Ensure all of the wires for the sensor are positioned away from engine components that could damage them.

If you drive mostly at low speeds, P2002 could be a recurring problem. You may want to consider taking your vehicle to a mechanic for a modification. They can reprogram the computer and remove the PDF, solving the issue.

P0304 – Cylinder 4 misfire detected

The cylinders in your engine are what provide its power. When they don’t fire correctly, your car will drive rough and be at risk for further damage. The P0304 OBD2 code is your first warning sign of misfires in your engine.

The P0304 code can be severe, so it’s not one you want to ignore. Read on below to learn more about what it means and how you can correctly diagnose it.

P0304 code definition

P0304 Code Definition (Generic): Cylinder 4 misfire detected

P0304 BMW: “Misfiring Of Cylinder 4, Damages TWC”

P0304 Dodge: Cylinder 1-10 Misfire Detected

P0304 Honda: Cylinder 4 Misfire Detected

P0304 Nissan: Cylinder #4 Misfire Detected

P0304 Subaru: #4 Cylinder Miss Fire

If you want to learn about the P0304 OBD2 code, this is the right place

What does P0304 mean?

The cylinders provide the power in your engines. This is where the spark plugs ignite the air/fuel mixture, generating the energy that turns the crankshaft. A misfire occurs when there isn’t enough fuel burning in a cylinder.

When the engine functions correctly, the cylinders fire in sequence to provide continuous power to the crankshaft. If the RPM of the crankshaft changes by more than 2%, this is when the engine will trigger the P0304 code.

The P0304 OBD2 code explicitly indicates a misfire in cylinder 4. You can use your car’s manual to locate this cylinder. It is common to also see P0300 and other misfire-related codes as well with P0304.

What are the symptoms of the P0304 code?

You will often experience serious drivability problems when the P0304 trouble code activates. These include:

The check engine light activates. If the light is solid, the change in the crankshaft RPMs is between 2% and 10%. A flashing or blinking light indicates a variance over 10%.
The engine runs rough. The engine may shake while idling. You may also notice jerking or hesitation from the engine while accelerating.
There’s difficulty starting or failure to start.
There’s a smell of fuel in the exhaust.
Engine power reduces.
Fuel economy reduces.

What are the causes of P0304?

The most common causes of the P0304 trouble code are:

Faulty or worn-out spark plugs
Faulty wires around the spark plugs
Faulty spark plug coils
Failure of the distributor
Faulty fuel injector

Engine misfires can also be a result of:

Leaks in the vacuum system
Fuel pressure is too low
Timing issues in the engine
Defective sensors (camshaft, crankshaft, oxygen, MAF, etc.)
Leaking head gasket
Fuel is too low quality for the engine

A misfire occurs when there isn’t enough fuel burning in a cylinder.

How serious is the P0304 code?

The P0304 OBD2 code is severe. Repeated misfires can damage your catalytic converter, ignition system, and other parts of your engine. The erratic performance also makes your vehicle a potential safety hazard. Stop driving your car when this code triggers, and refrain from driving until you’ve repaired the problem.

How to diagnose the P0304 code

Tools you’ll need:

Scan your system for other OBD2 trouble codes. Fix any that come up other than P0300-P0308.
Inspect the wires around the spark plugs for damage and loose connections.
If your engine has individual coil packs, switch the cylinder 4 pack with the one in cylinder 1. Clear the codes and test drive your car. If the misfire jumps to cylinder 1, the pack is faulty and should be replaced.
Visually inspect the spark plug for carbon build-up or other signs of fouling. It’s easiest to see if you have a new spark plug for comparison. Remove and clean the spark plug. If the build-up can’t be removed, replace the spark plug. A spark plug that’s shiny or blackened likely indicates the fuel mix is too rich.
Use a multimeter to measure the resistance of the spark plugs. Replace the wires if the reading is higher than 15,000 ohms.
Check the ignition coils. Remove the coil and touch the multimeter leads to both the primary and secondary ignition circuit. The primary ignition circuit typically reads between .4 and 2 ohms, and the secondary circuit between 6,000 and 10,000 ohms. Your vehicle’s manual can give you a more exact specification. If you get a 0 reading, the coil has an internal short.
Use a fuel pressure gauge to test the fuel pressure. Compare the reading to the specifications in your vehicle’s manual.
Unplug the fuel injector from your engine and probe the terminals with a multimeter. Compare the resistance reading to the specifications in your manual. A variance could indicate a faulty fuel injector.
Perform both an engine compression test and a leak down test. Mechanical problems like worn valve guides, burned valves, skips in the timing chain, and broken valve springs or pistol rings can lead to misfires. These tests will identify any failing components.

Common mistakes to avoid while diagnosing the P0304 code

Ensure you don’t overlook small issues, like loose connections and vacuum leaks. Be thorough in your engine inspection to make sure you’ve caught every potential source of the misfire.

What should you do to fix the code P0304?

If you’re not experiencing any symptoms, clear the code and test drive your vehicle. A single misfire may not indicate long-term problems. If the code does come back, continue with the steps below.

Replace any damaged wires found in your inspection, as well as any other components that failed diagnosis. Ensure all newly-installed items are functioning and all connections are secure.
Check the EGR system and fuel injectors for clogs. Clean out any that you find.
Test the sensors in your fuel and exhaust systems, including the crankshaft sensor, camshaft sensor, mass airflow sensor, and oxygen sensors. Inspect them visually for dirt or damage, then use a multimeter to ensure they’re receiving a charge. Replace any that are damaged.

Tips to avoid P0304 in the future

Issues with your air-to-fuel ratio may cause misfires. Check all the hoses in your system for leaks as part of your regular preventative maintenance. Air that gets into your system can make your air/fuel mix too lean. Alternatively, oil or carbon build-up on the spark plugs indicates a mix that’s too rich.

Using the wrong fuel can also cause engine misfires. More expensive fuel isn’t always the answer. Only use the grade recommended for your engine in your vehicle’s manual.

P0138: O2 Sensor Circuit High Voltage (Bank 1, Sensor 2)

Did your scan tool show the P0138 code? Do you wonder what it means and whether you can continue to drive?

Keep reading to have a first evaluation of the situation.

P0138 Definition: O2 sensor circuit high voltage (Bank 1, Sensor 2)
Code Type: Generic – P0138 indicates the same problem whether you’re having a Jeep, Toyota, or Dodge etc.
Can I drive with the P0138 code? Yes, but keep driving will cause internal engine damage.
Easy to fix? Intermediate level.
Cost: $20 – $95 (common)

Luckily, P0138 is safe to drive in a short period!

But to avoid more harm to the engine, let’s read on to know the causes and how to fix these problems!

What Does The P0138 Code Mean?

The P0138 is triggered when the downstream O2 sensor (bank 1) voltage is too high (>1.2 volts) for more than 10 seconds. This high voltage indicates that the oxygen level in the exhaust gas is abnormally low.

What Is The O2 Downstream Sensor’s Function?

Downstream oxygen sensors (located after the catalytic converter) monitor the conditions of the catalytic converter.

The less air in the exhaust gas (after passing the cats), the higher the downstream O2 sensor’s output voltage.

Because the catalytic converter already processed the exhaust gas, the oxygen level is stable. Therefore, a normal working downstream O2 sensor stays around 0.45 volts.

What Can Trigger The P0138 Code?

The sensor voltage being too high can be explained by two scenarios:

The reading is incorrect – results from the sensor’s wiring harness or the sensor itself
The reading is correct – results from rich conditions

I’ll explain the details in the below parts.

But first, let’s navigate your cause.

P0138 Causes Identification: Quick View

P0138 can appear alone or with other related codes. This table will help you navigate the root causes as well as the solutions for them.

Codes Combination	Causes	Solutions
Only P0138	Short in the O2 sensor signal circuit Faulty downstream O2 sensor	Find and replace the damaged wire Replace the sensor
P0138 + P0172/LTFT1<-10%	Too much fuel in the air-fuel mixture	There are several causes leading to this issue, further investigation is needed.

Note: The causes for each code combination are the most common ones. There can be some uncommon issues hidden under those codes.

P0138: Causes, Symptoms, and How to Fix

Now, you may have a general idea of what causes the P0138 error code.

Read on to learn how to pinpoint the root problem and stop being a part-changer!

Cause #1: Short In The O2 Sensor Signal Circuit

This is the first thing you need to check.

Short to battery voltage in the O2 sensor signal circuit will make the sensor’s output voltage increase, triggering P0138.

If the wiring is the problem, there is no symptom other than the Check Engine Light. This is because downstream O2 sensors are not used to adjust the air-fuel ratio (like upstream.)

And there will be no effect on the engine performance.

Cause #2: Faulty Downstream O2 Sensor

After making sure all the wiring is good, a faulty downstream sensor is very likely to be the cause of P0138.

Again, there will be no symptoms in this case.

How to fix it?

All you have to do is to replace the sensor.

Bank 1 sensor 2 is located right after the catalytic converter. The replacement process is straightforward and the part itself is inexpensive. So, you can totally do it by yourself.

Tips: You will need a hammer and a wrench to break the sensor loose.

You can watch this video from 1A Auto and replace the downstream oxygen sensor yourself to save money.

Cause #3: Rich Condition

A rich condition indicates that there is more than enough fuel in the air-fuel mixture,

This leads to a very low level of oxygen level in the exhaust gas, causing the computer to set P0138.

Symptoms of rich conditions causing P0138:

Poor fuel economy
Smell of gasoline
Slow acceleration
Negative long-term fuel trim on bank 1 (LTFT1<-10%)
Combination of P0138 and P0172

There are many different causes that can lead to this condition.

How to know which problem your car is having?

First, you need to monitor the long-term fuel trim on both bank 1 (LTFT1) and bank 2 (LTFT2.)

If Both LTFT1 and LTFT2 < -10%, the fuel pressure is too high (which is usually caused by bad FPR, fuel pump, fuel rail, etc.)
If LTFT<-10% and -5%<LTFT2<5%, a sensor (on bank 1) is causing rich mixture (upstream O2 sensor, MAF, MAP, IAT, etc.)

After all, rich conditions causing P0138 are not something you should worry about. Most of the time, replacing an inexpensive sensor will fix the problem. The hard part is to know which one needs to be replaced.

For further diagnosis, I wrote an article about the code P0172. Read it and you can exactly pinpoint your problem!

How Much Does It Cost To Fix The Code P0138?

9 out of 10 times, you can just spend less than 100 bucks to fix the issues related to the bank 1 downstream O2 sensor.

If you get negative long-term fuel trim (rich conditions,) there can be many different solutions depending on the causes.

The Estimated Repair Cost Of P0138

Solutions	Cost
Repair O2 sensor circuit	DIY: $10 – $20 Mechanic: $130 – $140
Replace (downstream or upstream) O2 sensor	DIY: $20 – $95 Mechanic: $100 – $450
Replace MAF/MAP sensor	DIY: $30 – $200 Mechanic: $80 – $280
Replace the IAT sensor	DIY: $20-$150 Mechanic: $40-$250
Repair IAT sensor wiring	DIY: $0-$20 Mechanic: $20-$75
Replace the fuel pressure regulator (FPR)	DIY: $50 – $200 Mechanic: $150 – $350
Replace the fuel pump	DIY: $50 – $850 Mechanic: $220 – $1,100

Note: The data in this table was collected in July 2022. The actual price depends on many factors, such as your car’s make and year, mechanic’s rate, etc.

How serious is the P0304 code?

How to diagnose the P0304 code

Tools you’ll need:

Scan your system for other OBD2 trouble codes. Fix any that come up other than P0300-P0308.
Inspect the wires around the spark plugs for damage and loose connections.
If your engine has individual coil packs, switch the cylinder 4 pack with the one in cylinder 1. Clear the codes and test drive your car. If the misfire jumps to cylinder 1, the pack is faulty and should be replaced.
Visually inspect the spark plug for carbon build-up or other signs of fouling. It’s easiest to see if you have a new spark plug for comparison. Remove and clean the spark plug. If the build-up can’t be removed, replace the spark plug. A spark plug that’s shiny or blackened likely indicates the fuel mix is too rich.
Use a multimeter to measure the resistance of the spark plugs. Replace the wires if the reading is higher than 15,000 ohms.
Check the ignition coils. Remove the coil and touch the multimeter leads to both the primary and secondary ignition circuit. The primary ignition circuit typically reads between .4 and 2 ohms, and the secondary circuit between 6,000 and 10,000 ohms. Your vehicle’s manual can give you a more exact specification. If you get a 0 reading, the coil has an internal short.
Use a fuel pressure gauge to test the fuel pressure. Compare the reading to the specifications in your vehicle’s manual.
Unplug the fuel injector from your engine and probe the terminals with a multimeter. Compare the resistance reading to the specifications in your manual. A variance could indicate a faulty fuel injector.
Perform both an engine compression test and a leak down test. Mechanical problems like worn valve guides, burned valves, skips in the timing chain, and broken valve springs or pistol rings can lead to misfires. These tests will identify any failing components.

Common mistakes to avoid while diagnosing the P0304 code

Ensure you don’t overlook small issues, like loose connections and vacuum leaks. Be thorough in your engine inspection to make sure you’ve caught every potential source of the misfire.

What should you do to fix the code P0304?

If you’re not experiencing any symptoms, clear the code and test drive your vehicle. A single misfire may not indicate long-term problems. If the code does come back, continue with the steps below.

Replace any damaged wires found in your inspection, as well as any other components that failed diagnosis. Ensure all newly-installed items are functioning and all connections are secure.
Check the EGR system and fuel injectors for clogs. Clean out any that you find.
Test the sensors in your fuel and exhaust systems, including the crankshaft sensor, camshaft sensor, mass airflow sensor, and oxygen sensors. Inspect them visually for dirt or damage, then use a multimeter to ensure they’re receiving a charge. Replace any that are damaged.

Tips to avoid P0304 in the future

Using the wrong fuel can also cause engine misfires. More expensive fuel isn’t always the answer. Only use the grade recommended for your engine in your vehicle’s manual.

If you want to learn about the P0700 OBD2 code, this is the right place

What does P0700 mean?

The P0700 OBD2 code triggers when a malfunction is detected in your transmission controls. Most modern cars have a specific control module for the automatic transition system called the transmission control module, or TCM.

The TCM’s role in your system is to monitor the transmission system’s sensors and send that data to the engine control module (ECM). If any issues are detected when the ECM reads this data, the P0700 trouble code is activated. Along with the check engine light, activation of this code triggers a failsafe mode. Your system will remain in this mode until the fault has been repaired and regular operation can resume.

The P0700 OBD2 code only tells you there’s some problem in your transmission system. You’ll need to dig a bit deeper to find the problem’s exact source, which makes your OBD2 scan tool your best friend when you need to fix a P0700 code.

What are the symptoms of the P0700 code?

You will likely notice drivability issues with code P0700, mainly caused by slips in the transmission. The most common symptoms include:

The five symptoms of the P0700 code

Activation of the check engine light,
Activation of fail-safe mode,
Hesitation or other problems when changing gears,
Stalls and rough driving,
Reduced gas mileage.

What are the causes of P0700?

Shift solenoid is defective,
The engine coolant sensor is defective,
Short or open circuit in TCM,
Faults in the transmission valve body,
TCM is faulty,
PCM is faulty (rare).

How serious is the P0700 code?

The P0700 is very serious. Issues with your transmission control system can prevent your car from changing gears, potentially making your car dangerous to drive. You should stop immediately driving when P0700 activates and avoid driving (aside from controlled diagnostic road tests) until you’ve repaired the problem.

How to diagnose the P0700 code?

While P0700 is a generic powertrain code, the specific fix can vary depending on your vehicle. Check your car’s manual and search for technical service bulletins applicable to your make and model before starting your diagnosis.

To diagnose the P0700 code, OBD2 scanner is the best choice.

Tools you’ll need: OBD2 scan tool.

Here are the steps:

6 steps to diagnose the p0700 code.

Scan for other trouble codes. Most of the time, P0700 is activated, but it isn’t the only trouble code. You will commonly see codes related to the shift solenoid. Diagnose these codes first. Since they’re more specific, it’s often easier to locate the issue.
Use your scan tool to read the freeze frame data. Pay particular attention to the RPM, throttle position, and engine torque readings. Compare the RPM’s input speed and output speed.
Depress the throttle slowly, starting above 45mph. Read the freeze frame data as you do this. The Slip Speed should never go over 50rpm. If it increases, the converter clutch is slipping. Alternatively, if the Slip Speed is steady, but the output shaft speed decreases, the transmission is slipping internally. Check your clutch packs and sprag clutches for wear.
Check your transmission fluid. It should be read and clear of debris, and the reservoir should be filled sufficiently. Also, check for signs of transmission fluid on your engine components or pooled fluid beneath your car, which could indicate a leak.
Drain the transmission fluid and check it for metal flakes. These are from mechanical wear in the transmission and are often seen when the transmission is failing. If these flakes are present, they may have clogged the solenoid, causing it to fail. Metal flakes may also indicate your transmission needs to be rebuilt or replaced.
Inspect all the wiring related to the transmission system. Replace any wires that are damaged, frayed, or shorted.

Common mistakes to avoid while diagnosing the P0700 code

The biggest mistake is to diagnose based on your car’s symptoms rather than reading the trouble codes. The drivability issues associated with P0700 can be misinterpreted as engine misfires. With a serious code like this, it’s crucial to conduct a thorough diagnosis using an OBD2 scan tool and ensure you’ve fixed the issue.

What should you do to fix the code P0700?

Replace any faulty or damaged wires found during your diagnosis. Ensure all connections are secure.
Locate the source of any transmission fluid leaks and replace the faulty component.
Drain your transmission fluid, then remove and replace the filter. Examine both the fluid and filter for debris. If any is present, flush your system and put in fresh transmission fluid. If there are many metal flakes in your transmission fluid, take your car to a transmission expert. There is a more serious issue in your system that needs to be addressed.
Replace the transmission shift solenoid if it is dirty or damaged.
Clear all OBD2 codes and take a test drive, replicating the conditions of the initial failure. If the P0700 code comes back, you may have more complicated electrical problems. Take your car to a mechanic for further diagnosis.

Tips to avoid P0700 in the future

Proper maintenance of your transmission system is the best way to avoid the P0700 code. Check your transmission fluid regularly and replace it when it gets dirty. If you see drips or puddles of transmission fluid in your garage or driveway, locate and fix the leak right away, even if no trouble codes are active.

P0303 – Cylinder 3 misfire detected

The P0303 code activates whenever cylinder 3 in your engine misfires. While a single misfire may not be cause for concern, repeated misfires are a sign of a bigger problem and could lead to long-term damage.

Finding the source of the misfire isn’t always easy, even when you know which cylinder it’s affecting. If other trouble codes are active, those can be a big help in isolating the issue. If not, there are steps you can follow to correctly diagnose the P0303 OBD2 code.

Diagnosing P0303 can be a time-consuming process. The good news is, it doesn’t always mean an expensive or difficult repair. Read on below to learn more.

P0303 Toyota code definition: Cylinder 3 misfire detected

P0303 VW code definition: Cylinder 3 misfire detected

If you want to learn about the P0303 OBD2 code, this is the right place

What does P0303 mean?

The generic powertrain code P0303 tells you there’s been a misfire in cylinder 3. You’ll usually see it along with the broader P0300 OBD2 code, which activates for a random misfire. Other trouble codes might come up, as well, including those relating to the air/fuel mixture.

While this code is generic, the fixes can vary depending on your car’s make and model. Always check your vehicle’s manual for recommended repairs before starting your diagnosis. Check for any technical service bulletins, as well, in case there’s a known issue for your car.

The exact placement of the cylinders in your engine depends on its size and style. In most V8 engines, cylinder 3 is directly behind cylinder 1, on the right side when you’re facing the engine. There are major manufacturers, however—most notably Ford—that number the cylinders from front to back, making cylinder #3 the third one back on the right side. Verify how your cylinders are numbered in your manual before starting your diagnosis.

What are the symptoms of the P0303 code?

If the misfire was a one-off problem, you may not experience any drivability symptoms. In most cases, though, they will be severe. The most common include:

Activation of the check engine light
Shaking or rough running from the engine
The smell of fuel in the exhaust
Jerking and hesitation when accelerating
Reduced engine power
Reduced gas mileage
Hard starts and stalls

The P0303 code activates whenever cylinder 3 misfires

What are the causes of P0303?

The most common causes of the P0303 OBD2 code are:

Worn or faulty spark plugs
Worn or faulty wiring around the spark plugs
Worn or faulty coil packs
Faulty distributor
Faulty fuel injector

Cylinder 3 misfires can also be caused by:

Vacuum leaks in the fuel or exhaust systems
Faulty camshaft sensor, crankshaft sensor, or oxygen sensor
Faulty or clogged catalytic converter
Low fuel pressure
Low engine compression
Fuel quality incorrect for the engine
Faulty computer (rare)

How serious is the P0303 code?

The P0303 trouble code is potentially quite serious. Misfires in the engine can cause damage to internal systems. The erratic driving that’s often a symptom of this trouble code also makes the vehicle unsafe to drive. Avoid driving your vehicle until you’ve repaired the issue.

How to diagnose the P0303 code

Tools you’ll need:

OBD2 scan tool
Basic tool kit (a screwdriver, a ratchet set, a socket set, etc.)
Digital multimeter
Fuel pressure gauge
Compression tester

Method:

Use the OBD2 scan tool to check for other trouble codes. If any others come up, fix those first.
Clear all codes and test drive your vehicle. If P0303 doesn’t come back and you’re experiencing no symptoms, it may have been a random misfire.
Inspect all the vacuum hoses in your system for air leaks. Be sure to feel any spots you can’t see for hidden damage or holes.
Inspect the ignition coils and wiring for damage and ensure the connections are secure. Check the spark plug wires for the same issues.
If your engine has movable coil packs, swap the cylinder 3 coil pack with the one in cylinder 1. Clear the codes and rescan your vehicle. If the misfire moves, the coil pack is likely faulty.
Visually inspect the spark plugs. If they’re coated in oil, corroded, or fouled by carbon build-up, clean or replace them.
Use a digital multimeter to test the spark plug wires. Remove each wire and connect one multimeter lead to each end. Compare the reading with your vehicle’s specifications.
Check the fuel injectors using a digital multimeter. Inspect the wiring for damage or loose connections.
Use a fuel pressure gauge to check your fuel pressure. If it’s too low, either the fuel pressure regulator or the fuel pump is failing.
Perform a compression test to check for mechanical causes of the misfire, like a burned valve or worn valve guide. This test will also tell you if the engine timing is off due to a skipped or misaligned timing chain.

Common mistakes to avoid while diagnosing the P0303 code

Many people start replacing big components before they check the little things like leaking hoses or damaged wires. Be thorough in your diagnosis so you don’t overlook potentially cheap and easy solutions.

What should you do to fix the code P0303?

Replace any damaged wires found during your diagnosis. If you located more than 2 bad wires around the spark plugs, it’s recommended to replace the entire set.
Repair or replace any leaking hoses or other sources of air leaks in the air intake system.
If the coil pack failed or the spark plugs were fouled, replace them.
Replace any fuel injectors that failed step 8 of the diagnosis. If your fuel pressure is still too low, replace your fuel pump.

P0303 explained

Tips to avoid P0303 in the future

Problems with the air-to-fuel ratio often lead to misfires. Leaks in the vacuum system make the mix too lean. Inspect your vacuum hoses periodically for leaks and ensure they’re fastened securely, away from any engine components that could cause damage.

P1131 Ford: Symptoms, Causes, and How to Fix

The OBD II code P1131 is quite common on most Ford Vehicles, including on Ford F150, Ford Ranger, Ford Taurus, Ford Explorer, Ford Expedition, Ford Mustang, and Ford Escort.

This article brings the information of the OBDII Error code P1131 displayed on Ford Vehicles.

Introduction to P1131 on Ford Vehicles

The error code P1131 is displayed by getting feedback from the Lambda (or the oxygen) sensor. The Lambda sensor is responsible for detecting the amount of oxygen in the exhaust gases. Based on that, the PCM (Powertrain Control Module) manipulates whether the engine is running on a lean or rich fuel mixture.

A lean running condition of the engine happens when the engine runs on less fuel or too much air, ultimately resulting in the error code P1131 on Ford vehicles.

An engine running on a lean mixture, may lead to sluggish acceleration and reduced fuel economy. Thus it becomes crucial to understand the P1131 on Ford Vehicles and ways to resolve this error code.

Code P1131 Ford Definition and Meaning

P1131 OBD2 code is displayed by getting feedback from the Lambda sensor.

In simple terms, the OBD II code P1131, when displayed on your Ford Vehicle, indicates the PCM detected a malfunction. By estimating the O2 amount, the PCM assesses whether the engine is running on a rich or lean fuel mixture. A lean mixture can give rise to various problems and thus displays the code P1131.

Whereas, an optimized fuel mixture is preferred because of the following-

Better Fuel Economy
Better Acceleration
Reduced tailpipe emissions
Prolonged engine life

In contrast, an engine running on a lean mixture can give rise to many issues that can appear combinedly or separately. That is discussed in the coming sections.

P1137
P1151
P1157
P0171
P0174

Symptoms of P1131 on Ford

The most visible symptoms of the P1131 code is-

Check Engine light ‘ON.’
Slow Acceleration
Poor fuel economy
Car Unable to Start

Moreover, there are some other symptoms for the P1131 code on Ford. But, the chances of encountering them are minimal-

Engine Stalling
Engine Knocking
A rise in Exhaust gas Emissions
Engine frequently misfires

Causes of P1131 on Ford

Five causes of P1131 Ford error code.

There can be various causes for the error code P1131-

1. Fuel System Malfunctioning

Issues in the Injectors, fuel filter, pump, etc., can result in a low quantity of fuel reaching the combustion chamber. The components listed below collectively or individually can cause Fuel System Malfunctioning-

Clogged Fuel filter: This may create a barrier to fuel passing the filter during the filtering process, thus creating a lean mixture.
Defective Fuel Pump: A lean mixture can be formed due to the fuel pump’s inability to supply the fuel with the required optimal pressure.

Faulty Fuel Injectors: The injectors are responsible for spraying the fuel into the combustion chamber. If they start to leak or become dirty, it may result in an interrupted fuel injection into the cylinder. The injectors with low pressure can result in the formation of a lean mixture.

2. Oxygen Sensor Inaccuracy

At times, it is possible that the sensor responsible for measuring the O2 in the cylinder malfunctions. Thus, reporting more oxygen in the mixture than the actual quantity. The amount of oxygen is proportional to the air quantity supplied. As a result, the PCM may display a lean mixture. Thus displaying the P1131 code.

3. Air Mass Flow Sensor Inaccuracy

The Air Mass Flow sensor estimates the amount of air that’s entering the cylinder. A faulty Air mass flow sensor may inaccurately assess the quantity of incoming air. Thus, as a result, the P1131 code may be displayed on the Ford vehicle.

4. Computer Malfunction

Though the chances of malfunctioning of an on-board computer are very low, however, a faulty on-board diagnostics system can inaccurately display the P1131 code.

5. Air Leaks

Innumerable hoses and gaskets are employed in an engine. These components are not built to last forever. Hence, it is possible due to incessant exposure to heat and pressure; any of these components gives rise to air leaks. Thus, air leaks can find its way into the engine, assisting in the formation of a lean mixture.

How Serious is P1131OBD II Code on Ford

Though the issues causing the P1131 code may not impact your vehicle’s functioning. However, if ignored, these can cause severe damage to other vital components in the long term.

A regular check-up or servicing might help to resolve the problems responsible for OBD II code P1131. Additionally, looking for the causes mentioned above can help fathom the issue much faster and easier.

Can You Drive with p1131?

It is not recommended to drive your Ford while the P1131 code is being displayed.

A petrol engine running on a lean mixture can cause problems like-

Reduced Performance
Engine Knocking (Inconsistent fuel combustion)
Damage to Piston

A Diesel engine running on a lean mixture may not result in the same problems but still can cause-

Low Output from engine
Engine Stalling

However, the vehicle with the P1131 code can cause sudden jerks with lagging acceleration. Moreover, it may reduce the efficiency of the vehicle while increasing emissions.

Tools Needed to Fix any of these Issues-

How to Fix the Code P1131 on Ford?

The first and foremost thing to be done when checking for the causes of the P1131 code is to connect a car diagnostic scanner to the car’s OBD. Running a diagnostic scan can give comprehensive information on the malfunctioned system to help resolve the issue promptly.

Moreover, if running an OBD diagnostics does not helps then, follow these steps to fix the code P1131-

Step 1– Check and Replace any damaged engine air-intake hoses

Step 2– Tighten the Spark Plugs Connecting Wires

Step 3– Check and Resolve any issue with Distributor assembly, like rotor or cap

Step 4– Check any fault in the fuel supply

Step 5– Lastly, but importantly check the wiring and connection of the Oxygen Sensor.

If the issue still goes undetected, then visiting a service center might help.

Frequently Asked Questions

Q) Why do lambda (oxygen) sensors fail?

Lambda sensor is continuously exposed to the high temperature of exhaust gases. Thus heat and vibration can cause damage to the wirings and connections. Moreover, the lambda sensor can be faulty due to corrosion as well.

Q) What happens if my O2 sensor is damaged?

A damaged O2 sensor doesn’t cause any serious problems. You can even drive with a bad O2 sensor. However, it may hamper other engine components in the long term and can even affect the overall vehicle’s performance.

Q) My Ford is driving fine, but it shows code P1131?

This could be because of the malfunction of any of the components responsible for diagnostics, or your Ford is driving fine because the issue is still in its initial phase and can increase over time.

P0017: Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor B)

Imagine starting your car engine or driving down the road and you notice the “check engine light” on. After an OBD2 scan, the P0017 pops up. But, what’s the next move?

Let’s find out.

P0017 Definition: Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor B)
Code type: Generic – P0017 indicates the same problem whether you’re having a Mercedes, Hyundai, Ford, etc.
Can I drive with the P0017 code? No, you can’t. It can cause severe damage to your engine.
Is it easy to fix? Intermediate to advanced levels.
Cost: $25 – $100 (common)

To understand the P0017 code better, I have narrowed this article into four parts: causes, symptoms, diagnosis, and solutions.

So, keep reading to learn more about this trouble code.

What Does The P0017 Code Mean?

Code P0017 indicates misalignment between crankshaft and camshaft position sensors (in bank 1 sensor B.) When the camshaft is greater than 9 degrees advanced, or 12 degrees retarded, compared to the crankshaft, P0017 is set.

Bank 1: The issue occurs in the engine side having cylinder 1.
Sensor B: The issue is found on the exhaust camshaft side.

Crankshaft vs. Camshaft

The crankshaft and camshaft are connected with a timing chain located at the end of the engine.

Camshaft: Allow the air-fuel mixture to enter the combustion chamber and releases the burnt exhaust gas.
Crankshaft: Harness the engine’s torque to rotate the camshaft.

These two shafts must have perfect timing for optimum control of the combustion. If the correlation is off, it leads to power loss, engine overheating, misfire, etc.

Engine timing

To prevent the correlation from going off, the engine timing must be controlled with the help of various parts:

Timing belt/chain.
VVT sprocket.
Timing belt tensioner.
Oil control valves.
Camshafts and crankshafts solenoid.
Camshafts and crankshafts.

In case any of the above parts goes wrong, it leads to the P0017 code popping up.

Other related trouble codes of P0017 include P0016, P0008, P0014, P0009, and P0019.

P0017 Causes Identification: Quick View

The P0017 code can occur either solely or in combinations with other related codes.

Refer to the table below to identify the root causes and solutions of P0017 and its related codes.

P0017 + P0016 + P0018 + P0019	Loose timing chain/belt	Fix timing chain/belt

Note: The causes for each code combination are the most common ones. There can be some uncommon issues hidden under those codes

P0017: Causes, Symptoms, And How To Fix

Regardless of the causes, the common symptoms of P0017 include:

Check engine light on.
Increased fuel consumption.
Reduced engine performance.
Engine noise and misfires (severe condition).
Rough accelerations.
Hard start engine problems.

Read further to identify the causes (from the most to least common) of P0017 with their relevant repairs.

Causes #1: Faulty or damaged timing chain /belt

The most common cause of the P0017 code is a faulty timing chain/belt.

In this situation, the timing chain/belt affects the engine timing, causing the P0017 code to pop up.

Other related codes may sometimes show, including P0016, P0018, and P0019.

In this case, replacing the defective timing chain/belt is the best option.

You can check this video about how to change the car timing belt from the Scotty.

Causes #2: Faulty camshaft/crankshaft position sensor

Damage in the camshaft/crankshaft sensor is another possible cause of the P0017 code.

The unique symptoms you’re likely to notice in this particular cause include:

Inconsistent sensor signals.
Engine stalling.
Car surging.
“Limp mode” on, causing gear shifting problems.

Replacing the damaged camshaft/crankshaft position sensor solves this problem. This process requires an expensive scan tool to relearn the sensors (which I highly doubt that you have one.) Therefore, I suggest you bring your car to a mechanic to handle it.

Causes #3: Damaged wiring/connectors to crank/cam sensor

A damaged wiring/connector to the crank/cam sensor leads to a failing cam/crank sensor. In return, it causes intermittent problems, which the PCM detects, thus throwing the P0017 code. The symptoms for this cause are the same as for a faulty crank/cam sensor.

In some cases, a damaged crank/cam sensor wiring can also result in a combination of the P0017 and P0014 code errors.

So, it is worth inspecting the wiring connections and ensuring there are no damaged or burnt wires. If any, replace them, and you will see the code error disappearing.

Causes #4: Bad oil control valve (VVT solenoid)

A bad oil control valve (VVT solenoid) alters retarding and advancing of the valve timing as needed.

A bad oil control valve (VVT solenoid) alters retarding and advancing of the valve timing as needed. In return, the engine develops oil flow problems which lead to the P0017 code manifesting. Also, the engine exhibits performance problems such as poor acceleration and rough running.

Nevertheless, the P0017 code error will sometimes appear in combination with P0014 or P0016.

In this case, replacing the bad oil control valve (VVT solenoid) is the best action you should take to do away with P0017.

Watch this video to learn how to diagnose the oil control valve.

Causes #5: Damaged timing belt/chain tensioner

Anything going wrong with the timing belt/chain tensioner affects the timing belt.

Anything going wrong with the timing belt/chain tensioner affects the timing belt. As a result, the cam and crank connection is interrupted, causing the pistons and valves to fail, thus, triggering the P0017 code. The symptoms of this issue are similar to those of a damaged timing belt/chain.

Apart from the common symptoms, the P0017 code may sometimes show in combination with the P0008 code.

The best way to solve this problem is to replace the timing belt/chain tensioner.

The way to change the tensioner is by AutoZone.

Causes #6: Slipped or broken cam/crank sensor tone ring

Slipped or broken cam/crank sensor tone ring interrupts the magnetic sensor from taking correct readings. As a result, the ECU indicates an inaccurate crank/cam position, thus triggering the P0017 code.

In this situation, changing the cam/crank sensor tone ring is the best solution. The process is simple as you can do it without special tools. However, you can call for mechanic assistance if you’re uncomfortable doing it yourself.

Causes #7: Dirty/ Low engine oil

The debris in an engine oil clogs the cam/crank, thus turning off the engine timing. Also, a low-quality engine oil fails to lubricate the engine parts properly. As a result, engine overheating occurs as well as breaking the rods which also turns off the engine timing.

Besides triggering the P0017 code, it can as well cause a combination of the P0017 with P0008 or P0014 codes.

Change the engine oil if it’s dark brown.

If this is the case, pouring down the engine oil and replacing it with a pure one is advisable. Also, you should develop a schedule in which you will be changing the engine oil without letting it overstay.

Before changing or adding the oil, it is advisable to clean the oil filter/oil cap. And if the oil filter/oil cap goes wrong, change it.

Causes #8: Faulty CMP/VVT actuator/exhaust VVT sprocket

A faulty CMP actuator/exhaust VVT sprocket hinders the valve timing from retarding or advancing as needed.

but the best option is to replace it.

VVT actuator replacement: DIY Guide Video around 30 minutes by ChrisFix.

Causes #9: Bad PCM (rare)

If you still see the P0017 code after solving all other causes, then check the PCM. Remember, the PCM is the main engine computer that ensures everything happening in the engine is perfect.

So, a bad PCM can trigger various trouble codes, although it rarely occurs. It can cause the P0017 code to pop up only or together with P0016.

If PCM is the problem, you should visit a mechanic shop for a replacement.

How Much Does It Cost To Fix The Code P0017?

You can fix most causes of the P0017 code by yourself with a few bucks. For instance, a new cam/crank position sensor can cost about $25-$100.

If you don’t feel comfortable replacing the parts, then a qualified mechanic comes in handy. The cost of hiring the mechanic can vary based on personal rates, but you can expect to pay between $95 and $200.

What Does The P112F BMW Code Mean?

The P112F BMW is a diagnostic trouble code (DTC) that indicates a problem with the manifold absolute pressure (MAP) sensor. The MAP sensor is used to monitor engine load by sampling the depression in the inlet manifold. When the throttle valve is opened, the inlet manifold pressure decreases. The MAP sensor sends a signal to the Digital Motor Electronics (DME), which uses this signal to calculate the amount of fuel to inject into the engine.

When the P112F code gets triggered in a BMW, it signifies an inconsistency between the indicated intake manifold pressure and the calculated mass airflow, a value derived from the throttle-valve angle. In simpler terms, there is a discrepancy between the expected engine load and the actual measured values.

In most cases, the vacuum leak is the culprit and the code could be addressed by fixing this issue.

P1101 Chevy Cruze – Intake Air Flow System Performance

One of the most common diagnostic trouble codes (DTC) Chevrolet Cruze users get is the P1101. The trouble code is expected because of the unreliable nature of the PCV (Positive Crankcase Ventilation) system that Chevrolet uses for most of its vehicles. This code and a few more will still reoccur even after replacing the whole PCV system.

There is a lot of misinformation on how this system works. Therefore, I’m going to go through a basic but clear overview of how the system works. Below is an outline of how the gas flows in a Gen 1 Chevy Cruze 1.4L Turbo PCV system.

The PCV system was created to help with the engine’s ventilation to have better efficiency and fuel economy from the engine. When the motor runs, some of the exhaust gas comes through the piston rings since there is no perfect seal, but most of it goes out through the car’s tailpipe.

The gas that comes through the piston ring enters the crankcase. This creates a positive pressure which has to be evacuated. The crankcase hosts an oil separator in the valve cover. The oil separator absorbs the oil vapor from the gas and redirects it back to the engine. The rest of the gas is directed through a chamber in the valve cover into the cylinder head and then enters the intake manifold, as shown.

There is one check valve at the entry of the intake manifold. This check valve is opened under vacuum with a PCV pressure control diaphragm to allow the gas in. The PCV pressure control diaphragm regulates the amount of vacuum produced by the intake manifold when the engine is under vacuum conditions on the crankcase (the ideal vacuum is 11-18 inches of water.)

The PCV pressure control diaphragm is shown below. A lot of people refer to it as the PCV valve or the PCV vacuum regulator diaphragm.

The PCV pressure control diaphragm is prone to failure. In most cases, this is the part you will have to fix to get rid of the P1101 code and similar ones depending on the problem’s length and severity.

Once the gas passes the first check valve, it flows through a corrugated hose that leads it into the second check valve at the turbo inlet, exiting it into the turbo inlet.

The P1101 code is mostly attributed to your PCV system’s condition, cleanliness, connections and wiring, the shape of the diaphragm, and sometimes the throttle body’s cleanliness. Various car parts will eventually develop carbon build-up and house deposits over a long period of use. This dirt may sometimes lead to the occurrence of the P1101 code.

In this article, you’ll learn about the P1101 code in great detail

The P1101 Definition

Definition: Intake Air Flow System Performance

In some other vehicles, the P1101 code is stored when the PCM detects a problem with the Mass Air Flow Sensor System (MAF). The PCM usually detects the problem when it runs its self-diagnostic test called the Key-On Engine Running (KOER) test. The problem is registered if the MAF voltage is lower or greater than the one set by the manufacturer.

What The P1101 Chevy Cruze Trouble Code means

The P1101 Chevy Cruze code is stored when the PCM detects a problem with the Intake Air Flow System’s performance. The problem is registered if the Intake Air Flow System’s performance is lower or greater than the one set by the manufacturer.

When you see this code, the issue lies within the realm of the Intake Air Flow System. This includes the PCV system, intake manifold, check valves, connectors, wiring, and any element associated with airflow along its vicinity.

Other codes that may be related to the P1101 code in Chevrolet Cruze vehicles (depending on the length and severity of the problem) are:

1. P0171 – Fuel Trim System Lean

2. P0106 – Manifold Absolute Pressure (MAP) Sensor Performance

3. P0507 – Idle Air Control – RPM higher than expected

Some Of The Symptoms Associated With The P1101 Code Are:

1. Rough idling

Due to the increased idle speed (measured in RPM – Revolutions Per Minute) of the engine. Idle speed is the rotational speed an engine runs when it is idling (the vehicle isn’t moving, but the engine is still running.) This number will vary depending on the car. In Chevy Cruze vehicles, the number ranges from 600-800 rpm depending on the engine cylinders and transmission mode.

2. Reduction in fuel economy – this will be apparent with an increase in the liters per 100km you use. The lower the number of liters stated, the better the fuel economy.

3. Engine running roughly – you will probably notice this when you start experiencing some shaking and bouncing sensation in the car, followed by odd sounds and irregular RPM.

4. Smoke from the tailpipe – smoke out of the tailpipe is associated with several causes such as oil leakage and condensation. The smoke may appear white or blue.

5. Hissing noise in the engine bay – this will imply that there may be a leak in the engine bay (punctured hose/broken connections) or a ruptured PCV pressure control diaphragm.

Causes Of The P1101 Trouble Code In Chevy Cruze Vehicles:

1. Broken or blocked PCV system hose – The blocked hose may cause the oil to be pushed up into the combustion chamber, causing the oil to burn inside the engine and out the exhaust pipe.

2. Check valves may be blocked/clogged. Pressure change in the PCV system or dirt accumulation in the check valves will prevent efficient gas flow. The result will be a low fuel economy due to the gas and oil mixture difference.

3. Air leakage before and after the Intake Air Flow System. This may be leakage along the corrugated hose connecting the turbo and the intake manifold.

4. The PCV pressure control diaphragm may have busted/ruptured. A faulty PCV pressure control diaphragm will affect the pressure difference in the PCV system resulting in a hissing sound.

5. Air filters may be blocked. Dirty air filters may prevent sensors from getting correct readings, therefore, resulting in reading errors.

How Serious Is The P1101 Code On Chevy Cruze?

The P1101 code is mostly not an indicator of a significant problem in your Chevy Cruze. However, it would cause internal problems in your engine if left unchecked for a prolonged period. Also, depending on the severity of the problem, it will result in rough driving, terrible fuel consumption, and power loss.

Moreover, the repair cost for the problem is relatively cheap at around $50 -$60 (applies when you are replacing the PCV regulator system by yourself – which is most of the time).

As a rule of thumb, always make sure you take every warning sign seriously, especially when you don’t know the problem. Early diagnosis and fixes will save you a lot of money down the road and maybe your life too.

Also, make sure to always do regular maintenance on your Chevrolet Cruze. Just because the check engine light isn’t on, it doesn’t mean that your car is running optimally.

How To Diagnose And Fix The P1101 Code Quickly On Any Chevy Cruze

Before you pop the hood and take a look inside, you will need an OBD-II scanner.

These are the step-by-step procedures you should follow:

1. Use the OBD-II scanner to detect all the trouble codes stored in the car system.

2. Remove the PCV system cosmetic cover. Start the engine and let it run while the car is idle. Place a finger on the opening of the PCV pressure control diaphragm if you notice a hissing sound from it. If the hissing sound stops, you may have found your problem. If that is the case, all you have to do is replace the entire PCV cover since the diaphragm is fixed to it. However, it is advisable to keep diagnosing more problems to see if there is a more significant underlying issue, i.e., faulty PCV check valves.

3. Turn the engine off and locate the corrugated hose connected to the PCV check valve on the intake manifold. The hose is brittle; it may break if not carefully handled. Disconnect the hose from the base. Use a torch to look inside the pathway from which the hose has been disconnected.

4. You may notice an orange or pink like a nipple at the back of the pathway. That is the check valve. If it is not visible, use cotton swabs and rubbing alcohol to clean the region. Check again. If the check valve is not visible, this may be the problem that you were looking for. A replacement part (for the entire intake manifold from a certified seller) and further analysis from a certified mechanic may be required.

5. The next step is to check the PCV hose connected to the two check valves. Without disconnecting the other side, blow air into the hose; it should blow freely. The next step is to suck air back from the hose, after which it should block the airflow. It will need to be replaced if it doesn’t do any of the above. A hissing sound will be present if the hose is leaking while the engine is running.

6. Fix the leaks, if any, and re-run the scanner test to see whether the code is still there. If you followed all of these procedures, your problem should be fixed.

7. If the replacement unit doesn’t fix the problem, you will have to test the PCM to determine if it is terrible. A lousy PCM will have to be replaced, but this would require a qualified professional’s extensive work.

Tips To Help You Avoid Getting The P1101 Code In The Future

1. Regular cleaning and maintenance. Most car troubles can be fixed by a regular cleaning habit and a short, frequent visit to the mechanic.

2. Check for vacuum leaks regularly.

Frequently Asked Questions

How to replace the intake manifold?

The process is simple and straight forward. Please read this article to learn how to do it.

Can I fix the P1101 trouble code by cleaning the PCV?

Sometimes, yes. Carbon build-up and depositions tend to clog pathways and restrict airflow. A regular cleaning schedule and maintenance check may help fix the problem. However, you should make sure to check for any underlying issues even if the problem disappears.

How long can I drive my Chevy Cruze with the P1101 code?

From a statistic standpoint, you would have to reach 50000 – 70000 miles before replacing any of these parts. However, this will depend on the car model, year of make, and usage.

Is fixing the problem worth it? Should I get a better car instead?

You may be tempted to get rid of your vehicle mainly because the problem is likely to occur time and time again. However, the cost of repairing the car is more economical than what you will get by selling it. The critical parts of the vehicle are quite reliable, hence, worth the keep.

Should I buy any generic replacement parts?

No. As mentioned earlier, even the most certified replacement parts will eventually fail. It is advisable to get the most reliable one of them all for a longer life span, in which case you will need the ones from General Motors themselves.

P1260 Ford Code: Vehicle Theft Detection?

Attention, Ford owners! If you’re encountering the P1260 code on your vehicle, you’ve come to the right place.

This article provides a comprehensive overview of the P1260 Ford code. From its meaning and severity to symptoms, causes, and repair solutions, we’ve got you covered.

So, let’s get started!

P1260 Ford: A Brief Summary

Here’s a quick summary of the P1260 in Ford vehicles to provide you with essential information!

Definition: Theft Detected, Vehicle Immobilized
Severity: Medium
DIY Skill Level: Intermediate
Continue To Drive?: Yes
Estimated Repair Cost: $100 – $500

What Is The P1260 Error In Ford Vehicles?

The P1260 code in Ford vehicles is related to the Passive Anti-Theft System (PATS). It indicates a “theft condition,” which occurs when the PATS detects either an incorrect signal or no signal at all from the chipped key. The purpose of the PATS is to prevent the unauthorized starting of the engine by immobilizing it when an incorrect key is used.

Several components are involved in triggering this code. When you insert the chipped key into the ignition, it transmits a unique code to the PATS transceiver module. This code is then sent to the instrument cluster (IC), which verifies its authenticity. If the key is determined to be valid, a signal is sent to the powertrain control module (PCM), allowing the engine to start.

However, if the IC receives an incorrect or no signal from the chipped key, the P1260 code is triggered, and the engine is disabled, preventing it from starting. It’s important to note that this code can also occur if a new instrument panel cluster (IPC), IC, or PCM is installed without proper programming, even if the vehicle is not equipped with PATS.

P0016: Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor A)

Your check engine light turns on, throwing the P0016 code? Well, that’s an alert, signaling troubles in your car engine timing. But, what next?

Let’s take a brief look at the information below.

P0016 Definition: Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor A).
Code Type: Generic – P0016 indicates the same problem whether you’re having a Chevy, Dodge, or Ford, etc.
Can I drive with the P0016 code? No, keeping driving can cause more damage to the engine.
Easy to fix? DIY to advanced levels.

Due to its severity, most people get confused and frightened when they see the P0016 code. Stay calm, I will tackle this error code in-depth, including its causes, diagnosis, symptoms, and quick solutions in this article.

Let’s dive in for more details!

What Does The P0016 Code Mean?

P0016 code stands for Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor A). This indicates that the engine timing is having problems resulting from the misalignment in the crankshaft and camshaft positions.

Bank 1: Means that the problem is on the engine side containing cylinder 1.
Sensor A: Indicates that the issue is affecting the intake camshaft side.

Crankshaft Vs. Camshaft

The crankshaft and camshaft are connected with a timing chain located at the end of the engine.

Camshaft: control the valves, which allow the air-fuel mixture to enter the combustion chamber and release the burnt exhaust gas.
Crankshaft: Harness the engine’s torque to rotate the camshaft.

These two shafts must have perfect timing for optimum control of the combustion. If the correlation is off, it leads to power loss, engine overheating, misfire, etc.

Engine Timing

To prevent the correlation from going off, the engine timing must be controlled with the help of various parts:

Timing belt/chain.
VVT sprocket.
Timing belt tensioner.
Oil control valves.
Camshafts and crankshafts solenoid.
Camshafts and crankshafts.

In case any of the above parts goes wrong, it leads to the P0016 code popping up.

Other related trouble codes of P0016 include P0017, P0008, P0014, P0009, and P0019.

P0016 Causes Identification: Quick View

There are various causes of the P0016 DTC. Usually, a faulty camshaft/crankshaft position sensor is the main one.

In most cases, you may see the P0016 only, but sometimes, it may occur in combination with other related codes. Check the table below to understand those specific combinations and their specific causes.

P0016: Causes, Symptoms, And How To Fix

Although the causes of P0016 may show varying symptoms, here are the most common ones that you should look out for.

Check engine light on
Poor car engine performance
High fuel consumption
Engine hard start
Rattling sounds from the engine

The onset of these signs needs quick action. So, keep reading to learn more about the causes and what to do if you encounter one.

Cause #1: Faulty Timing Chain/Belt

The timing belt/chain helps in synchronizing the crankshaft and the camshaft timing.

For some reason, the timing chain/belt may skip a few teeth, putting the cam and crank out of sync.

Faulty timing chain/belt symptoms:

Loss of power when the car is cruising (Timing chain/belt skipped one tooth).
Knocking sounds from the engine (Timing chain/belt skipped two teeth).
Can’t start, no pressure when doing a compression test (Timing chain/belt skipped three teeth).
P0016 may appear alone or come along with P0299, P0399, P000B, P0017, P0018, or P0019.

If this is your case, replacing the faulty timing chain/belt will solve the problem. Having that job done is not complex because no special mechanic experience is needed.

Replacing a timing belt is not quite a complicated job. With the thorough instruction from Mr. Scotty Kilmer, you can totally do it by yourself to save some money.

Cause #2: Faulty Camshaft/Crankshaft Position Sensor

The camshaft/crankshaft position sensors are responsible for monitoring the cam and crank position.

When one of these sensors get faulty, it conveys inaccurate data, leading to mismatched ignition timing and fuel delivery. The PCM sets up the P0016 code to signal this problem.

Faulty camshaft/crankshaft position sensor symptoms:

Engine vibrations and misfire
Gear shifting problems
Engine stalling
Rough idling

To solve this problem, you need to replace the camshaft/crankshaft position sensor. Bear in mind that you should choose the OEM parts for the best result.

Let’s find out how Danny from O’Reilly Auto Parts replaced a Camshaft Position Sensor!

If you want to replace a Crankshaft Position Sensor on your own, watch this video right away! Chris will show you how to do it step by step.

Cause #3: Damaged Wiring/Connectors To Crank/Cam Sensor

The wiring/connector linking to the crank/cam sensor can be burnt, unplugged, or shorted. As a result, the functions of the sensor and other engine timing parts are compromised, triggering P0016. Note that the DTC may appear as P0016 only or as P0016+P0344.

Damaged wiring/connectors to crank/cam sensor symptoms:

Ignition problems
Poor idling
Failure in tachometer
Engine misfiring

If the wires are unplugged, locate and plug them in to fix the issue. However, you should replace the wiring/connectors to the crank/cam sensor if they are shorted, burnt or their insulation is damaged.

Cause #4: Faulty Oil Control Valve (VVT Solenoid)

Oil control valve’s function is to alter the camshaft rotation, giving the engine better performance at different RPMs. This component is only available if your engine has the variable valve technology (VVT.)

If a faulty oil control valve is the culprit, either the car has poor gas mileage at low RPM or lack of power at WOT.

Besides, the P0016 may show alone or in combination with P000B, P0017, P0018, P0019, or P0344.

Replacing the oil control valve (VVT solenoid) should fix the problem. This process is not difficult and you can do that right in your garage.

Cause #5: Damaged Timing Belt/Chain Tensioner

Over time, the timing belt/chain material wears out and gets overstretched, causing it to fail.

For that reason, a timing chain/belt tensioner is used to keep the timing belt/chain more tightened.

A tensioner is supposed to tighten timing chain/belt. The P0016 code displayed on the OBD scanner may result from a faulty tensioner.

If the timing chain/belt tensioner gets damaged, the timing chain/belt becomes loose. This will cause engine timing problems, which the PCM will detect and set up P0016 to send signals of the issue.

Similarly, this cause can trigger a combination of the P0016 code with P0399 or P0344.

In this case, you need to replace the timing belt/chain tensioner.

Cause #6: Slipped Or Broken Cam/Crank Sensor Tone Ring

Due to the crank rotation impact, the sensor tone ring may get loosened, damaged, or fail to shear the key aligning them. Sometimes, the DTC can occur as P0016 only or as P0016 + P0340.

If your cam/crank sensor tone ring is the culprit, replacing it is the best option to go for eradiating the code.

Cause #7: Dirty/Low/Wrong Engine Oil

Dirty engine oil is a common cause of faulty oil control valves. This happens when the debris builds up, thus blocking the valves.

Similarly, low/wrong engine oil can also affect the engine timing. If the oil has a wrong viscosity, the camshaft phaser fails to work right.

Either way, dirty/low/wrong engine oil affects the engine timing badly, which triggers the P0016 and sometimes P0016+P000B.

Have a brief look at this picture to determine the oil condition in you car and take action needed immediately.

If this happens, flush the engine oil and ensure that you use compatible engine oil to avoid the same mistake.

Cause #8: Bad CMP Actuator/Exhaust VVT Sprocket

Most vehicles use the CMP actuators/exhaust VVT sprocket to change the cam position and advance or retard the valve timing. If it goes bad, it will cause the crankshaft and camshaft to misalign.

Since the PCM controls the VVT solenoids that apply oil pressure on the actuator, it will detect the change and set up the P0016 code. In this case, a replacement of the CMP actuator/exhaust VVT sprocket is needed to solve the P0016 code error.

Cause #9: Bad PCM (Rare)

Once every possible cause of P0016 DTC is checked out, a bad PCM remains the only culprit. Similarly, this issue can trigger a combination of P0016 with P0017, P0018, and P0019.

The problem occurs once the PCM fails to control the engine ignition and spark, though it is rare. However, if it happens, the PCM is a complicated part that requires you to have a qualified mechanic to fix it. The mechanic can decide either to reprogram the PCM or replace it, depending on the severity of the problem.

How Much Does It Cost To Fix The Code P0016?

The cost of fixing the P0016 code depends on whether you are doing it yourself or using mechanic services. DIY will cost you a few dollars. For example, replacing a camshaft/crankshaft position sensor costs $25-$100.

The mechanic services are usually charged depending on the working hours, costing about $95 – $200. However, the cost of hiring a mechanic will vary, considering factors such as mechanic rates, car model, your location, etc.
