Sharp engine failure lights up the electrical components of the whole vehicle.

The engine fault light comes on mainly for the following reasons:

1 oil quality problem; 2 the throttle valve is dirty; 3 One cylinder is not working well, so it is necessary to check and replace the spark plug and cylinder line; 4 oxygen sensor, three-way catalytic failure;

If your car doesn't shake, the idle speed is unstable, and the exhaust gas is not fully burned, I suggest you disconnect the battery directly, connect it again in a few minutes, and eliminate the fault light.

If not, I suggest you check the camshaft sensor.

This sensor is under the hood, close to you is the intake valve, and one inside is the exhaust valve, which can be removed for cleaning. If the light is still on, it is recommended to replace it.
