What does the engine light on the car dashboard mean?

[EvanAnn]

The engine light displayed on the car dashboard indicates an engine malfunction. Possible reasons include: 1. The need to replace the air flow sensor or oxygen sensor, spark plugs or ignition coils, or unclean engine cylinders with carbon deposits causing engine knocking; 2. Poor combustion state, low-quality fuel, etc. However, the specific cause needs to be diagnosed by reading the fault code with specialized equipment at an after-sales service center. The ways the engine light appears on the dashboard and solutions: 1. There are two ways the engine light can illuminate: yellow light or red light. If it's a red light, immediately go to a 4S shop for inspection and repair as the fault is severe; if it's a yellow light, the fault may not affect driving but should still be checked as soon as possible. 2. The car can read the fault code through the OBD interface using a computer. If you are interested in the vehicle's mechanical/electronic systems, you can purchase a Bluetooth module for the OBD interface to view and clear fault codes with a laptop or Android phone.
