Product Details

The Denso Tire Pressure Monitoring System (TPMS) Sensor - OE Manufactured, part number 550-2801, is engineered for vehicles that rely on precise sensor communication with the TPMS module.

Installation Notes and Tips

After installation, the vehicle may require a TPMS relearn or initialization procedure according to the manufacturer’s service steps. Denso notes that some do-it-yourself installations still need a trusted repair shop to complete relearn programming. Verify wheel fitment, sensor frequency/application, and vehicle-specific relearn requirements before final assembly.
