What does the yellow engine fault light mean?

[DeLouis]

There are generally two situations when the engine fault light comes on. The first situation is the self-check when the car is powered on, not only does the engine fault light come on, but other fault lights also come on, and they will turn off after a few seconds, which is a normal phenomenon. The second situation is when the fault light stays on constantly, which is the ECU alerting that there is a fault in the engine. Here are the solutions: Can continue driving: After the engine fault light comes on, if the car can still continue to drive and there are no abnormalities, this may be due to a fault in one of the engine's sensors or an error in the ECU system. For safety reasons, it is best to drive at low speed or stop and have it checked and repaired at a nearby repair shop. Cannot continue driving: After the engine fault light comes on, if the car cannot continue to drive or even cannot start, this situation is caused by a fault in the fuel pump or ignition system, and the only option is to call for a tow truck.
