What Causes the TPMS Light to Illuminate?
2 Answers
tpms light illumination indicates that the tire pressure of a certain tire is at a critical point or the sensor battery is low. Below are specific methods to eliminate the TPMS light: 1. Start the car's engine and turn on the instrument power. 2. Check the tire pressure of each tire, ensuring all four tires have the same pressure. 3. Press and hold the tire pressure reset control button until the TPMS light goes off, completing the reset. Below is an introduction to the TPMS light: 1. The tire pressure indicator light is a light on the vehicle used to alert the driver to the tire pressure condition. When the tire pressure is abnormal, the tire pressure monitoring indicator light will illuminate. 2. Through the indicator light, the driver can promptly know the tire pressure condition and proceed with repairs, effectively avoiding tire blowouts and improving driving safety.
I've seen the TPMS light suddenly come on several times on the highway, usually caused by low tire pressure, such as a tire leak or insufficient air due to temperature drop. Once when I was driving in winter, the tires contracted from the cold for half an hour, and the light kept flashing. When I drove to a service station for inspection, the pressure was indeed low. Additionally, this could happen if the sensor malfunctions, like when the battery is depleted or the sensor is loose, especially common after tire replacement without system reset. For safety, I would immediately find a safe place to stop, check with a manual tire pressure gauge, and if normal, try pressing the TPMS reset button in the car to restore it. If that doesn't solve the issue, it's best to quickly visit a repair shop to avoid affecting braking performance. Developing a habit of checking tire pressure monthly can reduce such problems.
