What to Do When the Built-in Tire Pressure Monitoring Sensor Runs Out of Power?
1 Answers
If the built-in tire pressure monitoring sensor runs out of power, it is generally recommended to directly replace the sensor module with a new one. Tire pressure monitoring is designed to automatically and continuously monitor the air pressure in the tires while the vehicle is in motion, alerting the driver to any leaks or low pressure to ensure driving safety. There are three common types of tire pressure monitoring systems: Direct Tire Pressure Monitoring: The direct tire pressure monitoring system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is then transmitted wirelessly from inside the tire to a central receiver module, which displays the pressure data for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, resulting in a faster rotation speed compared to the other tires. By comparing the differences in rotation speeds among the tires, the system monitors the tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS) Overview: 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 a full direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect low pressure in multiple tires simultaneously. However, it still cannot provide real-time pressure data for all four tires as effectively as a full direct system.
