What Causes a Tire Pressure Monitoring System Malfunction?
2 Answers
Tire pressure monitoring system malfunctions can be caused by: depleted battery in the tire pressure sensor, sensor signal failure, sensor circuit failure, or body control module failure. The solution is: check if there is a tire malfunction. If it is found that the tire pressure system malfunction caused a false alarm triggering the tire pressure warning, you can directly reset the tire pressure warning light. In the car's central console settings, there is a "SET" button for tire pressure reset to manually turn off the warning light. The tire pressure monitoring system, abbreviated as "TPMS", can automatically monitor various conditions of the tires in real time by recording tire rotation speed or through electronic sensors installed in the tires, providing effective safety protection for driving.
I've also encountered TPMS (Tire Pressure Monitoring System) failures while driving. The most common issue is sensor battery depletion - those coin cells need replacement every 5-6 years, and even tire changes can damage the sensors. Another problem is signal interference, like false alarms near high-voltage power lines. Sometimes the vehicle's computer system acts up, especially after switching to winter tires without proper recalibration. I recommend keeping a $10 mechanical tire gauge in the car - much more reliable than electronic systems. When parking, avoid sharp stones, and remind technicians to protect sensors during tire repairs to prevent accidents. If the warning light stays on but actual pressure is normal, you'll probably need a dealership computer reset.
