What does the engine light on the dashboard mean?

[VanMaggie]

The engine light on the dashboard indicates an engine malfunction. Possible causes include: the need to replace the air flow sensor or oxygen sensor, spark plugs or ignition coils, unclean engine cylinders, carbon deposits causing engine knocking, poor combustion state, or poor fuel quality. The specific cause needs to be diagnosed by reading the fault code with a specialized computer at an after-sales service center. Solutions: 1. There are several ways the engine fault light can illuminate: steady yellow light, flashing yellow light, steady red light, or flashing red light. If the red light is on, go to a 4S shop immediately for inspection and repair as the fault is severe. If the yellow light is on, the fault may not affect driving, but it should still be checked as soon as possible. 2. The car can read the fault code through the OBD interface using a computer.
