What is the reason for the stop light appearing on an EFI car?
2 Answers
The reasons for the stop light appearing on an EFI car are as follows: 1. Overheating issue: If the engine temperature is too high during driving, the temperature warning light will come on, and the STOP light will also illuminate, reminding the driver that the engine has malfunctioned and needs to be inspected at a 4S shop. 2. Engine oil pressure issue: If the car indicates a lack of engine oil during driving, but upon inspection, it is found that there is no lack of oil, it means the oil pressure is relatively low, and the stop warning light will also come on. Replacing the engine oil can solve this problem. 3. Sensor damage issue: If the vehicle itself has no faults but the sensor is damaged, the warning indicator light will also come on.
When the 'STOP' light comes on in an EFI car, it's really alarming. I've experienced it several times, and it usually means the car is in serious trouble: first, the water temperature might be too high, indicating a cooling system problem; second, the oil pressure might have dropped, meaning the engine isn't getting lubricated; third, it could be a charging system failure, like the alternator failing or the battery dying. Once, a friend of mine was driving when the light came on, and he immediately pulled over to find the coolant had all leaked out. If he had kept driving, the engine would have burned out. If this happens, don't hesitate—pull over right away, turn off the engine, and check basic fluid levels and gauges. If necessary, call a tow truck to take it to a professional shop. Regular maintenance of oil and coolant can help prevent such issues.
