Features and Functionality

1. O2 sensor test

Strength:

If you realize a drastic drop in fuel mileage then you need to check the O2 sensor.

Launch CReader 3001 will help you to effectively determine if the O2 sensor is properly functioning.

A properly functioning O2 sensor analyzes the amount of oxygen available in a car’s exhaust stream.

The information is turned into an effective voltage signal used to control the fuel ratio as well as emission.

A defective sensor transmits erroneous voltage signals to vehicles onboard computer.

As a result, the vehicle will consume more fuel and emits fumes that pollute the air.

Other signs that may point to a bad oxygen sensor include rough idling, engine stalling, and weak acceleration.

Besides, you can detect a strong smell and Malfunction Lights being subsequently turned on.

The good news is that Launch CReader 3001 will tell when there is a problem with the O2 sensor.

If you are a DIY then you can replace the O2 sensor if it is defective.

Replacing a defective O2 sensor can prevent possible damage to the catalytic converter.

Catalytic converter cost thousands of dollars to replace.

Weakness:

2. EVAP test

Strength:

When you suspect that there is a leak in the fuel system then it’s advisable to perform EVAP test.

Fortunately, Launch CReader 3001 can retrieve EVAP codes.

The EVAP system helps to check fuel vapor leaks including when there is a missing gas cap or a loose gas cap.

The EVAP monitor points out vapor leaks when pressure or vacuum is applied to vapor lines, fuel tank, and charcoal canister.

A diagnostic trouble code is generated when EVAP detects a leak that exceeds 0.040 or 0.020 for vehicles manufactured after 2000.

Equally, if the monitor detects an absolute lack of airflow during the time the purge valve is opened it will generate a diagnostic code.

Launch CReader 3001 will help you to retrieve the diagnostic codes ranging from P0440 to P0457.

Even better, the inbuilt DTC lookup library will define the codes simplifying analysis and repair process.

Weakness:

Launch CReader 3001 does not display accurate EVAP codes in vehicles.

If you are not careful you may end up replacing parts that have no faults or leaks at all.

You will also discover that it does not retrieve EVAP codes in heavy trucks.
