If you Satisfied with your order. We would aprreciated if you left us a Review. Your feedback is very important to us. New, taken off From new wheels. 315 MHz Multi-application Sensor. TPMS tool required for Re-Learn Process. Real Time Pressure Signal. Sensor Nut Torque (in/lbs). Pre-programmed but a TPMS tool is needed to do the “re-learn”. Works with all major TPMS tools. Valve core, stem and hex nut treated against corrosion. Valve cap seal minimizes air loss. Pivoting valve stem makes installation easier and accommodates a wide range of wheel rim profiles. TPMS Sensors typically need to be replaced for one of the following three reasons. 1Battery Life – Estimated life of 5 to 10 years or 100k miles. 2Damage – Caused by accidents, pot holes, etc. 23 Corrosion – Typically from road salt (cold weather climates) or galvanic corrosion. Note: It typically makes sense to replace all sensors at once since batteries have similar life spans. Should I replace my TPMS sensor when replacing my tire? A If the new set of tires is expected to cross over the TPMS battery threshold consider. C Otherwise TPMS manufacturers recommend using a service kit to replace TPMS. Components to prolong life.
