Can You Still Drive with the Engine Yellow Light On?

[StCatherine]

You can drive with the engine warning light (yellow) on, but you should get it checked as soon as possible. The engine fault signal is issued by the ECU (Engine Control Unit), which controls all the electronic components of the engine, such as the electronic throttle, fuel injectors, alternator, fuel pump, etc. It covers various systems including intake, exhaust, fuel, ignition, and timing. If the engine warning light is on, you must visit a nearby repair shop for inspection. There are two scenarios when the engine yellow light appears on the car dashboard, as described below: The first scenario occurs when the car's power is turned on: The vehicle performs a self-check, during which not only the engine yellow light but also other warning lights will illuminate and then turn off together. This is a normal phenomenon. The second scenario occurs after the car is started: If the engine fault yellow light remains on, this indicates that the ECU is alerting you to an engine fault, which is an abnormal condition.
