What is the reason why the Cruze fault light usually lights up?

The Cruze fault light comes on for the following reasons:

1. The main reason why the Cruze fault light comes on is that the throttle valve or the engine has too much carbon deposit, and the oxygen sensor fails, which leads to the imbalance of the mixture ratio, so the engine fault light is easy to come on. It is recommended to clean up the carbon deposit in the throttle or engine in time.

2. If you drive at a low speed in the urban area for a long time, the fault light will light up easily. If it is detected by other diagnostic computers, an error corresponding to the fault code may appear. It is best to go to a regular 4S shop to check, determine the cause of the failure, and eliminate the failure.

3. Crankshaft position sensor failure (P0336): When the crankshaft position sensor fails, the tachometer on the instrument panel does not work, and the engine starting time is prolonged, which affects the shift timing of the automatic transmission.

4. Spark plug failure: the resistance of the ignition coil of the spark plug is too small or low-frequency harmonics are generated, which can be solved by replacing the spark plug.

5. Transmission oil pressure control solenoid valve (P27 15): When the clutch is disengaged, the transmission oil pressure control solenoid valve is not connected. Million car purchase subsidy
