Why Does the Engine Yellow Light Come On While Driving?

[LaLila]

There are two scenarios when the engine yellow light on the car dashboard illuminates. Here are the details: 1. When the car's power is turned on, the vehicle performs a self-check, which is a normal phenomenon. 2. If the engine fault yellow light remains on after the car is started, it is an abnormal phenomenon. Additional explanations of situations that may occur after the engine yellow light comes on: 1. The car cannot start after the light comes on. This may be caused by a faulty fuel pump or ignition components, and you may need to call for a tow truck. 2. The fault light is on, but there are no noticeable driving abnormalities. This could simply be a sensor malfunction or a false fault. In this case, you can continue driving temporarily, but for safety reasons, it is best to drive at low to medium speeds and immediately head to the nearest repair shop for inspection. 3. The engine fault light is on, the vehicle can still be driven, but there are severe vibrations, lack of acceleration, or other symptoms. Continuing to drive under these conditions may worsen the fault, damage the engine, or cause other issues. Therefore, it is not recommended to continue driving. Instead, call for assistance and wait for support.
