What does it mean when the engine yellow light on the car dashboard is on?

[DiIsla]

There are two situations when the engine yellow light on the car dashboard is on: 1. When the car's power is turned on, the vehicle will perform a self-check. At this time, not only the engine yellow light will be on, but other fault lights will also light up together, and then they will all go out, which is a normal phenomenon; 2. After the car is started, the engine's fault yellow light remains on, which is the ECU reminding that there is a fault in the engine, and this is an abnormal phenomenon. When the engine fault light on the dashboard is on, you can try to start and turn off the vehicle three times in a row, or turn off the engine and disconnect the negative terminal of the engine battery, wait for 30 seconds, reconnect it, and then try to start the engine.
