What are the symptoms of a faulty tire pressure monitoring system?
2 Answers
A faulty tire pressure monitoring system cannot automatically monitor tire pressure and temperature in real time. When the tire experiences high pressure, low pressure, or high temperature, it fails to provide timely warnings, which can affect driving safety. In some vehicle models, when the tire pressure monitoring system is damaged, the screen will display a message prompting the need to service the tire pressure monitoring system. The functions of the tire pressure monitoring system are: 1. It provides timely warnings in case of rapid or slow air leakage when the tire is punctured; 2. It alerts when tire loosening causes unbalanced friction, leading to tire temperatures reaching 70 degrees Celsius to prevent blowouts; 3. It warns when the tire pressure falls below the vehicle's set limit due to prolonged lack of inflation, preventing low pressure from causing tire temperature rise and blowouts. The method to reset the tire pressure monitoring system is: 1. Ensure the vehicle's tire pressure is within the normal range; 2. Park the vehicle on a flat surface and turn off the engine; 3. Power on the vehicle, press and hold the tire pressure monitoring button, and after 5 seconds, release the button upon hearing an alarm sound to complete the reset successfully.
I recently encountered this issue while driving—the tire pressure monitoring warning light kept staying on, and no matter what I tried, it wouldn’t go off. Even after I used an air pump to inflate the tires, it was still there, flashing, which made me really nervous. Sometimes, the tire pressure readings on the dashboard were erratic, showing absurd values like negative pressure or unrealistically high numbers, which were clearly abnormal. Looking back, it might be a sensor issue, as these sensors are installed inside each tire and can wear out over time due to exposure to the elements. Driving under such conditions is extremely unsettling—if there’s an actual tire leak, I wouldn’t even know, increasing the risk of a blowout or uneven braking. My advice is not to delay like I did—if the light stays on, get it checked at a shop immediately to avoid potential hazards.
