Why is the engine indicator light on?

[DiRyan]

The reasons for the engine indicator light being on are: 1. Inaccurate coordination between various components of the engine leads to poor combustion state; 2. The car lacks power, and the engine noise is too loud or there is obvious knocking sound; 3. Poor fuel quality or unclean engine cylinders with severe carbon deposits. Precautions for engine maintenance: 1. Check the antifreeze in time during winter, especially in northern regions where temperatures are low. Using ordinary water instead of antifreeze can easily cause freezing, which may lead to radiator cracking, pipe blockage, and overheating; 2. The intake system needs regular inspection. A failed air filter can cause engine failure and increase carbon deposits.
