What is the reason for the yellow engine light

The fault light of the yellow light on the engine indicates that the car's engine has intermittent failures, because the engine control system detects the working state of the engine or the sensor signal is out of alignment, and it needs to be repaired as soon as possible.

Common internal combustion engines are gasoline engines and diesel engines. Gasoline engines usually convert chemical energy into mechanical energy. In order to keep the cylinders of the engine working at normal temperatures, it is necessary to cool the cylinders and cylinder heads. The most important part of the engine is the body, which is the skeleton of the engine and houses the main parts and components of the engine. Water-cooled engines are commonly used in automobiles. There are cooling water jackets near the cylinder and cylinder head. The cooling water continuously circulates in the water jacket to take away heat and play a cooling role.
