TPMS and Maintenance of Valve-Stem Mounted Sensors

According to the Tire Industry Association (TIA), routine maintenance of valve-stem mounted sensors should be performed every time a tire is repaired or replaced. This maintenance involves disassembling the sensor and replacing a few key components (gasket, valve core, valve nut and valve cap). This will help ensure a proper air tight seal and clean away any corrosion that may have built up between services. TPMS sensors are battery operated with a life range of 4-10 years. Once the battery has expired the whole sensor must be replaced. TPMS sensors are produced by several different manufacturers and may use different radio frequencies, so care must be taken to select the appropriate sensor for the specific vehicle being serviced.
