TPMS (Tire Pressure Monitoring System) Replacement Sensors from Orange Electronic are the best alternatives to original equipment TPMS parts. They meet specifications based on vehicle year, make, and model. TPMS sensors measure tire pressure and then transmit data to a vehicle's ECU (electronic control unit). Orange Electronic uses an exclusive patented sensor with a valve-separated design that incorporates a ball joint fitting so the sensor can be placed in the best location to prevent damage when being serviced. To reduce maintenance costs, only the valve needs replaced if only the valve breaks. Click here for OE Part Number Cross-Reference.
