ACDelco TPMS Program

TPMS Guide

TPMS Sensors typically need to be replaced for one of the following three reasons:

  • Battery Life Estimated life of 5 to 10 years or 100k miles
  • Damage Caused by accidents, pot holes, etc
  • 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?

  • If the new set of tires is expected to cross over the TPMS battery threshold consider replacing the TPMS Sensors now to avoid tire mounting fees
  • Otherwise TPMS manufacturers recommend using a service kit to replace TPMS components to prolong life
