What is the reason why the Corolla tire pressure monitoring does not display tire pressure?

Corolla tire pressure monitoring does not display tire pressure may be due to a problem with the tire sensor, which needs to be replaced. Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. When the tire pressure is too low or there is a leak, the system will automatically issue an alarm. Indirect tire pressure monitoring: When the pressure in a tire decreases, the weight of the vehicle will cause the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the purpose of monitoring tire pressure is achieved. Indirect tire pressure warning systems actually rely on calculating the rolling radius of the tires to monitor pressure.
