What are the symptoms of a damaged tire pressure sensor?

[DiHector]

The symptoms of a damaged tire pressure sensor include the inability to detect tire pressure. Some vehicles may display a tire pressure sensor fault warning, while others may show no tire pressure information on the dashboard. There are three common methods of tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts when tire pressure is too low or when there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the weight of the vehicle causes the rolling radius of that tire to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the differences in rotation speeds between tires, the system monitors tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): This system combines the advantages of both the direct and indirect systems. It is equipped with direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to using only a direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires, as a direct system can.
