Why does the tire pressure monitoring light keep coming on?
1 Answers
Tire pressure monitoring light keeps coming on due to abnormal tire pressure. The tire pressure monitoring system automatically monitors the tire pressure in real-time while driving and alerts the driver in case of tire leaks or low pressure to ensure driving safety. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: The system usually alerts when the pressure is below 1.8 bar or above 3.0 bar. In this case, the tires need to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure monitoring system is not reset in time, it will still record the previous data, causing the tire pressure monitoring light to stay on. Simply reset the tire pressure monitoring system to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which is installed inside the tire and connected to the tire inflation valve, monitors the tire pressure. If the sensor is damaged due to impact while driving, the tire pressure warning light will also come on. In case of sensor damage, the only solution is to replace it with a new one.
