What are the reasons for the engine warning light coming on in a car?

[McKatherine]

The reasons for the engine warning light coming on in a car are: 1. Sensor damage or poor contact; 2. Poor engine maintenance; 3. Failure to add engine oil as required; 4. Engine carbon buildup or knocking; 5. Clogged air filter. An engine is a machine that can convert other forms of energy into mechanical energy. It was invented in the UK and can refer to both the power generation device and the entire machine including the power unit (such as gasoline engines, aircraft engines). Its types include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), and electric motors.
