TPMS Rebuild Kits help extend the life of TPMS Sensors. Over time, TPMS components can degrade, affecting sensor operation. Rebuilding the valve portion of TPMS sensors insures an air tight seal and reduces the chance of early sensor replacement. Use Denso TPMS Rebuild Kits to service your TPMS Sensors every time a tire is dismounted to ensure safe operation. Denso TPMS service kits include all the necessary parts to rebuild and repair TPMS components.
