What Is a Tire Pressure Monitoring System Sensor?
A tire pressure monitoring system sensors (TPMS) alerts a driver when there is a substantial change in pounds per square inch (PSI) for one of the four tires. TPMS is a federally-mandated standard to increase driver and vehicle safety. When a TPMS light illuminates in the vehicle’s instrument cluster, it is time to pull over and check each tire for leaks, abrasions and foreign objects that may have punctured the tread or sidewall.
