What is the reason why the Corolla tire pressure monitoring does not display tire pressure?
2 Answers
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.
When driving my Corolla, I've encountered the issue of the tire pressure monitoring system not displaying the tire pressure several times. This is mostly due to the sensor battery being depleted, which typically lasts about four to five years before running out of power. Another common reason is the system not being reset after changing new tires, or signal interference when the weather is too cold. Poor wiring contact or a faulty receiving module can also cause this problem. My usual solution is to first measure the pressure of all four tires with a tire pressure gauge to ensure they are normal; then, drive a kilometer or two on a flat road to see if the system reactivates. If it still doesn't work, I take it to a professional repair shop for inspection, where the sensor might need replacement or the software might need an update. For prevention, regular maintenance checks on the tire pressure system and battery health can avoid such troubles. After all, it's related to driving safety, so don't delay in addressing the issue if the display doesn't show up.
