What does the engine symbol on the dashboard mean?

[GabrielaFitz]

The engine symbol on the dashboard indicates an engine malfunction. The reasons include: 1. The need to replace the air flow sensor or oxygen sensor, spark plugs or ignition coils, or the presence of carbon deposits inside the engine cylinders causing engine knocking; 2. Poor combustion state; 3. Poor fuel quality; 4. It is normal for the engine warning light to illuminate for a few seconds and then turn off after starting the car. This is the car's computer self-check and does not require repair. The car can read the fault code through the OBD interface using a computer. The engine warning light can appear in the following ways: 1. Yellow light continuously on, yellow light flashing; 2. Red light continuously on, red light flashing. If the red light is on, it indicates a very serious fault, and you should go to a 4S store for inspection and repair immediately. If the yellow light is on, the fault may not affect driving, but you should still check it as soon as possible.
