So, let’s get started!
P0345 Code: Quick Overview
But first, let’s take a look at the P0345 code overview!
Definition: Camshaft Position Sensor A Circuit Malfunction (Bank 2)
DIY Skill Level: Advanced
Continue To Drive?: No
Estimated Repair Cost: $50 – $200
What Does the P0345 Code Mean?
The P0345 diagnostic trouble code (DTC) indicates a camshaft position sensor A circuit malfunction in Bank 2. This code is commonly found in Nissan, Ford, Infiniti, and Lexus car models.
In modern vehicles, the engine’s camshaft plays a crucial role in the precise timing of the intake and exhaust valves. The camshaft position sensor, located near the camshaft, monitors the position and speed of the camshaft. This sensor sends the recorded information to the engine control module (ECM), which uses it to determine the optimal fuel injection and ignition timing.
When the camshaft position sensor A circuit in Bank 2 malfunctions, the ECM doesn’t receive the expected signals from the sensor. As a result, the code P0345 will be set.
This code is often associated with other DTCs like P0340 (Camshaft Position Sensor A Circuit Malfunction Bank 1), P0344 (Camshaft Position Sensor Circuit Intermittent), and P0349 (Camshaft Position Sensor A Circuit Intermittent Bank 2). These codes may share similar causes and symptoms, making it important to diagnose and address them collectively for a comprehensive repair.

How Serious is the P0345 Code?
The P0345 code is considered a high severity level as it can lead to significant issues, including potential no-start situations that may leave you stranded. While it may not cause immediate breakdown or safety hazards, it is crucial to address the issue promptly to avoid potential engine performance problems and further complications.
Continuing to drive with the P0345 code can be risky as it may lead to serious issues such as stalling, misfires, or poor acceleration. To ensure safe driving conditions and prevent potential engine damage, it is strongly recommended to diagnose and repair this problem as soon as possible.
Symptoms of the P0345 Code
You can observe various symptoms when the P0345 trouble code appears, including:
- Check Engine Light, traction control, and/or “Check VSC” light illuminated
- Engine misfires or runs roughly
- Decreased engine power and performance
- Hesitation or stumbling during acceleration
- Engine stalling or difficulty starting
- Poor fuel efficiency
What Causes The P0345 Code?
Possible causes of P0345 may include:
- Faulty/Contamination camshaft position sensor
- Wiring or connector issues in the sensor circuit
- Sensor alignment or synchronization problems
- Timing belt/chain problems affecting the camshaft’s position
- Bad crankshaft position sensor
- Electrical problems such as a short or open circuit
- ECM or PCM software issues
How To Diagnose And Fix The Code P0345
Now, it’s time to explore the diagnosis and repair process. In this section, we’ll guide you through the necessary tools and parts, outline a step-by-step procedure, and discuss the level of DIY repairs you can undertake. By following this guide, you can save money on repairs and better understand your vehicle’s problem.
Essential Tools and Parts
To diagnose and repair the P0345 trouble code, you may need the following tools and parts:
- OBD-II scanner or code reader
- Basic hand tools (screwdrivers, wrenches, sockets)
- Camshaft position sensor
- Crankshaft position sensor
- Wiring connectors and terminals
- Electrical tape or heat shrink tubing for wire repairs
- MAF sensor cleaner spray
- Connect the OBD-II scanner or code reader to the vehicle’s diagnostic port to retrieve the stored trouble code.
- Inspect the wiring and connectors related to the camshaft position sensor in Bank 2 for any visible damage or loose connections.
- Check the camshaft position sensor for any dirt or corrosion. Clean it if needed.
- If no apparent issues are found, use a multimeter to test the resistance and voltage of the sensor and its circuit. Compare the readings obtained to the manufacturer’s specifications.
- If the sensor is faulty, replace it with a new one, ensuring proper alignment and secure connection.
- Test the crankshaft position sensor voltage if the camshaft sensor works properly. If the reading is different from the manufacturer’s specifications, replace it.
- Perform a PCM test if the above steps cannot help you fix the P0345 code.
- Clear the trouble code and test drive to ensure the issue has been resolved.
- Before replacing the camshaft position sensor, keep the engine cool to avoid potential burns.
- Take caution when working with electrical connections and wiring to prevent short circuits or damage.
- Refer to the vehicle’s service manual or online resources for specific instructions and component locations.
