What's the matter with the tire pressure sensor failure?
1 Answers
Tire pressure sensor failure means the tire pressure sensor is damaged and cannot monitor the tire pressure. Some cars will display a tire pressure sensor failure alarm, while others may not show tire pressure information on the dashboard. There are three common types of tire pressure monitoring methods: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire's air 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 the tire pressure is too low or there is a leak. Indirect Tire Pressure Monitoring: When the air pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel 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 air pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of both the above systems. Direct sensors are installed in two diagonally opposite tires, and a four-wheel indirect system is also equipped. 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 like a direct system.
