What does the engine symbol on the car dashboard mean?

[Clyde]

The engine symbol on the car dashboard is an engine fault warning light, indicating that there is a fault in the engine. This light illuminates when the engine's electronic control system, sensors, or wiring malfunction, alerting the driver to promptly visit a 4S shop to address the issue. Modern cars generally do not experience serious mechanical problems, but sensors and electronic systems are the most prone to failure. It is advisable to avoid using low-quality fuel during regular use, as poor-quality fuel can also trigger the engine fault light. The engine is equipped with a knock sensor; when knocking is detected, the ECU will take corrective measures. If the vehicle requires high-octane gasoline but the owner consistently uses low-octane fuel, the engine fault light will illuminate. The car dashboard is a device that reflects the working status of various vehicle systems, commonly including indicators such as the fuel level light, washer fluid light, electronic throttle light, and front/rear fog light indicators.
