Tire Pressure Monitoring (TPM) Sensor - Description

DESCRIPTION






NOTE: Replace the valve stem assembly and tire pressure sensor mounting screw with each tire change.

One tire pressure sensor (1) is mounted to a valve stem (2) specifically designed for mounting the pressure sensor (1) in 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 (1) must be replaced. The TPM system operates on a 433 MHz radio frequency. The tire pressure sensor valve stem (2) looks similar to a standard valve stem with the tire mounted on the wheel. To visually identify a tire pressure sensor/valve stem, the valve stem cap (3) is longer than a standard valve stem.

NOTE: This vehicle uses the 433 MHz TPM sensor. Although 315 MHz and 433 MHz sensors are identical in size and shape, they are not interchangeable. Always make sure the correct sensor is being used. A RKE-TPM Analyzer can be used to determine the sensor's frequency without having to dismount the tire.

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.)

The serviceable components of the tire pressure sensor are:

- Tire pressure sensor (1), including all components below
- Valve stem (2), including screw (4), core, and cap (3)
- Valve stem core (not shown)
- Valve stem cap (3)

The valve stem caps and cores used 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.
