What components should be replaced when the TPMS sensor is removed from the wheel?



The TPMS grommet, sensor locking nut, nickel-plated core, valve cap, and any other service kit components need to be replaced every time a tire is serviced or when a clamp-in type TPMS sensor is removed from the valve hole. Snap-in TPMS sensors must have the rubber insert replaced during service. 

Replacing the sealing components on a TPMS sensor can ensure that your TPMS sensor is being used to its maximum potential.
