What Causes TPMS to Fail?

TPMS Direct explains some of the causes of TPMS failure

Sensors fail primarily due to battery failure or improper service procedures. Initially there will be a learning curve for installing and checking the Tire Pressure Monitoring System (TPMS), but most service technicians quickly learn how to identify and service the system efficiently.

  • Sensor batteries can become discharged and fail – the internal lithium battery is not serviceable, and it has a life expectancy of approximately 5-7 years.
  • Installing the incorrect valve core will cause failure – TPMS sensors require a special nickel-plated valve core instead of the regular copper or brass valve core
  • Normal tire changing procedures can damage a TPMS sensor – this includes flat repairs, new tire replacement, snow tire change or a wheel upgrade
  • Pulling a typical looking rubber valve stem out of the wheel will lead to a broken sensor. TPMS systems now use either metal or rubber valves
  • Over tightening a new sensor valve will result in a broken sensor
  • Typical road hazards – collisions, potholes, curbs – can damage the TPMS system
  • TPMS sensors contain delicate electronics that are subject to failure over time

Like most things, TPMS are not invincible. Curbs, potholes, and just streets in general pose hazardous conditions to our aftermarket wheel and TPMS Sensors. Unfortunately we cannot control that but we can save you from the dealership! Our sensors are 100% OEM replacement, they are the same exact sensors that are in there right now. We buy in large quantities direct from manufactures to ensure that we always have availability, and that we provide the best prices anywhere.
