How To Deal with Engine Malfunction Light？

When the engine malfunction light on the car dashboard lights up, many car owners feel anxious and worried about serious problems with the vehicle. In fact, when the fault light is on, it does not necessarily mean a major malfunction. Mastering the correct handling methods can help car owners cope scientifically and avoid unnecessary losses.

Firstly, remain calm and make a preliminary assessment of the situation. The fault light is divided into two types: yellow and red. When the red light is on, it should be taken seriously immediately. At this time, the vehicle should be parked in a safe area as soon as possible, the engine should be turned off, and rescue should be contacted, as this usually indicates a serious fault with the engine, and continuing to drive may cause component damage. If the yellow light is on and there are no obvious abnormalities in the vehicle, you can first observe the driving status and pay attention to whether there is weak acceleration, abnormal noise, shaking, etc. If everything is normal, you can continue driving, but arrange for maintenance as soon as possible.

Secondly, try a simple self-examination operation. After the vehicle is turned off, wait for about 30 seconds to restart. In some cases, the malfunction light may turn off due to a temporary sensor false alarm. If the light still lights up after restarting, you can check if the fuel tank cap is tightened. Poor sealing of the fuel tank cap can cause abnormal pressure in the fuel system, triggering the fault light. After tightening and driving for a certain distance, the light may turn off on its own.

Finally, timely professional maintenance and daily prevention. If the above methods are ineffective, it is necessary to go to a 4S store or a regular auto repair shop, use professional equipment to read the fault code, accurately locate the problem, such as sensor failure, abnormal fuel system, excessive emissions, etc., and then carry out targeted repairs. In daily driving, regularly maintaining the vehicle, using qualified fuel, and avoiding sudden acceleration and braking can reduce the probability of the malfunction light coming on and ensure stable engine operation.
