What causes the maintenance warning light to come on in a car?
1 Answers
The reasons for the engine maintenance warning light to come on are as follows: 1. If the car cannot start after the engine maintenance warning light comes on, it may be due to a fuel pump failure or an issue with the ignition system. In this case, the car cannot be driven, and you should call for roadside assistance to have it towed. If the warning light is on but does not affect driving, it might be a sensor malfunction or a false alert. In such cases, you can consider driving to a nearby repair shop for inspection. 2. If the engine maintenance warning light comes on and the car can still be driven but exhibits severe shaking, slow acceleration, or lack of power, do not continue driving. Continuing may cause severe engine damage or lead to other unnecessary faults. It is recommended to pull over to the right immediately, call for assistance, and wait for roadside support. 3. A yellow warning light indicates an engine fault that does not affect normal operation but requires maintenance. A red warning light indicates a serious engine fault that normally requires immediate repair. In special circumstances, you may drive cautiously but must monitor the engine's condition closely. Note that electronic fuel injection engines have self-protection control systems. There are many reasons for the engine warning light to come on, and in some models, even a loose connection of the headlights can trigger the warning light. The light does not always indicate a major fault. Generally, if the warning light comes on in a new or relatively new car, it suggests an issue in a certain aspect of the vehicle.
