On vehicles equipped with Tire Pressure Monitoring (TPM), one tire pressure sensor (6) is mounted to each wheel in place of the traditional tire valve stem. Each sensor has an internal battery that lasts up to 10 years. The battery is not serviceable. At the time of battery failure, the sensor must be replaced.

The TPM system operates on a 433 MHz radio frequency. The 433 MHz sensors (1) can be easily identified by the part number.

CAUTION: Although additional sensors operating at 433 MHz sensors are available and are used in other applications, they are not interchangeable. Always make sure the correct sensor is being used and be sure to replace the sensor with the correct part number.

NOTE: Once mounted inside a tire and wheel assembly you are not able to visually see the difference between this sensor and other 315 MHz and 433 MHz sensors. At that point, the TPM/RKE Analyzer 9936, with the Scan Tool may be used to identify the sensor frequency or the tire can be dismounted allowing visual inspection of the sensor body and part number.

The TPM sensors are designed for original style factory wheels. It is not recommended to install a tire pressure sensor in an aftermarket wheel (This could cause sealing and system performance issues). Do not attempt to install a tire pressure sensor in an aftermarket wheel. If aftermarket wheels are installed and do not contain tire pressure sensors, the system will not function properly and the driver will be continuously notified of a system malfunction.

The serviceable components of the tire pressure sensor are:

Sensor-To-Wheel Seal (2) and Metal Washer (1)
Valve Stem Cap (4)
Valve Stem Core
Valve Stem Nut (with pressed-in washer) (3)

NOTE: Any time a sensor is installed on a wheel, a new Sensor-To-Wheel Seal (2), Metal Washer (1) and Valve Stem Nut (3) must be installed to ensure air tight sealing. A service kit is available.

The valve stem caps and cores are specifically designed for the tire pressure monitoring sensors. Although similar to standard valve stem caps and cores, they are different. The valve stem cap has a special seal inside to keep moisture and corrosion out. The valve stem core has a special nickel coating to protect from corrosion.
