The main causes of a TPMS sensor fail is due to battery failure or improper service procedures. But, most service technicians know how to install, check and service a vehicle’s TPMS systerm effectively. The sensor battery can become discharged and fail——the internal lithium battery is not serviceable. It is a promary battery. The ideal design from OE is 10 years of battery life, but the actual use in accordance with the owner's driving habits, driving enviroment different, the general life expectancy of  approximately 5-7 years or 80k-100k miles.All TPMS sensors should have a 100% replacement rate. 

When purchasing a new set of tires, you are making an investment in your vehicle. Since 2008, the federal government has mandated that all new cars be fitted with a Tire Pressure Monitoring System (TPMS) to alert a driver when tire pressure becomes low. This system not only protects you from dangerously low tire pressure, but also your tires and your vehicle from premature wear and poor fuel economy. A Tire Pressure Monitoring System (TPMS) service kit is a package that typically includes new rubber valve stem seals and nuts to secure the tire pressure sensor to the wheel. It is important that these parts are replaced each and every time you purchase new tires. If a TPMS service kit is not used when a tire is replaced, a slow leak may develop around the old seal in the valve stem, causing tire pressure to consistently fall below safe levels, and triggering a TPMS sensor alert on your dashboard. By installing a new TPMS service kit on all wheels when your tires are replaced, you are protecting yourself and your investment for the long-term.
