Quality Guarantee
All of our sensors go through the following checks to ensure quality:
-Sensors are installed in a special test chamber to simulate operating environment and then checked for battery level, signal strength, pressure & temperature reading accuracy, and proper activation.
-Sensor body inspected for cracks and separations
-Pressure sensor port inspected for blockage
-Valve body inspected for bends, damaged threads, and excessive corrosion
-Inside valve body checked for seized valve cores
-Entire sensor cleaned of excess dirt, grime, and tire dust
All of our TPMS sensors are fully guaranteed for 30 days. If you experience any problems with our sensors we will replace or refund (depending on availability) at not cost to you. We want ALL of our customers to be satisfied so if you ever have a problem PLEASE contact us!

Please read:
*May fit other models. Please verify part number matches the one on your part that needs replacement!
We do our best to make sure our compatibility information is correct but it is the buyer's responsibility to ensure that the part will fit their vehicle. If you are unsure please ask before making a purchase and we will be glad to assist you!
*Your vehicle will require programming after replacement of any TPMS sensors (in most circumstances).
OEM type sensors have a unique ID that must be "relearned" by your vehicle's tire pressure monitoring system (TPMS) once they are installed. The procedure varies from one vehicle to the next and ranges in complexity. Most major tire shops and service stations will be equipped to complete the relearn once installed. If you would like some specific information on the programming procedure for your vehicle or have any other TPMS related questions we are happy to offer our expert advice!
*Stock photos
Typical condition of sensors we sell. Actual parts will be clean and in very good condition but may have some minor corrosion or staining.
*Genuine OEM Sensors Guaranteed!
If our sensors are listed as "OEM", they are genuine original equipment manufacturer made parts, just like your vehicle came with from the factory with. Beware of cheap imitations that offer "OEM fit" as they are generally of inferior quality. Most of our sensors listed as "aftermarket" are produced by the same OEM suppliers and are of the same quality. We do not import cheap aftermarket or reproduction sensors, period.
