What to Do When the Built-in Tire Pressure Monitoring System Runs Out of Battery?

[Bryan]

If the battery of the built-in tire pressure monitoring sensor is depleted, the general solution is to directly replace it with a new sensor module. Tire pressure monitoring automatically and continuously checks the air pressure in the tires while driving and alerts the driver to leaks or low pressure to ensure driving safety. There are three commonly used methods of tire pressure monitoring: Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure 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, making it rotate faster than the other tires. By comparing the rotational speed differences between tires, the system monitors the tire pressure. Essentially, the indirect tire pressure alert system relies on calculating the rolling radius of the tires to monitor pressure. Introduction to the 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 four-wheel indirect system. Compared to a fully 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 effectively as a direct system.
