What does "tire pressure sensor fault" mean?

The "tire pressure sensor fault" message tells that there is a problem with one or more tire pressure monitoring system (TPMS) sensors. This system is designed to warn the driver when one or more tires are significantly under-inflated, leading to tire failure and possible loss of vehicle control. If you see the tire pressure sensor fault, the pressure in one or more of your tires is too low, and you should stop immediately to check your tires. If the pressure is low, inflate the tire to the recommended pressure. If the pressure is normal, the sensor may be faulty and need to be replaced.
