Here are the specific reasons for the engine warn light to come on: 1. Reason one: When the engine fault light comes on. First, confirm whether there are any obvious abnormalities before and after the engine fault light comes on. If not, it means the engine only has excessive exhaust emissions. In this case, you can drive a short distance and then go to a repair shop or 4S store for inspection. If there is obvious abnormal noise, it may be due to severe excess of the mixture or a problem in a certain system causing engine misfire and resulting in shaking. In this case, it is recommended to immediately turn off the engine and contact professionals for repair. 2. Reason two: Aspects that cause the engine fault light to come on. Poor gasoline quality can lead to incomplete combustion of the mixture in the cylinder, and it is also prone to carbon deposits. The presence of carbon deposits in the intake tract and piston top can cause poor atomization, leading to incomplete combustion. During cold starts, especially when the weather temperature drops sharply, the computer's temperature correction may cause the light to come on during startup, but it will stabilize relatively once the temperature drops to a certain level. If the engine has been driven for too long, the weakened working characteristics of the spark plugs can cause the pollution light to come on.
