What happened to the faucet light?

The light on the car faucet is due to misoperation or car emission problems.

This faucet light is an engine indicator light, which is used to show the working state of the vehicle engine. When the key door is opened, the engine indicator light will automatically go out when the vehicle is self-tested. This phenomenon is normal. However, if the indicator light is on all the time, it means that there is something wrong with the engine of the vehicle, such as poor combustion state of the engine, poor fuel quality or dirty carbon deposit inside the engine cylinder. Or the owner made a mistake. If the engine fault light is on while driving, it will automatically disappear under normal circumstances. If it doesn't disappear, the owner should pay attention, and the engine of the car may be faulty.
