- Some aftermarket wheel valve stem holes are located further from the wheel rim than original equipment wheels. When using the TPM special tool to activate a sensor, ensure the tools antenna is no further than 15 cm (6 in) from the sensor.
- Aftermarket wheel valve stem locations can cause a sensor to not function correctly.
- The sensor activation procedure may have to be repeated up to 3 times before determining a sensor is malfunctioning.
- Occasionally sensors can become mislocated due to previous tire rotations where the sensor learn procedure was not performed. Always learn the sensors to ensure the DTC set is for that actual physical corner of the vehicle. Refer to Tire Pressure Sensor Learn (W/O UH3) or Tire Pressure Sensor Learn (W/UH3) .
- Occasionally sensor transmissions are not received by the RCDLR due to vehicle level RF interference.
