Tire Pressure Sensor: Description and Operation
Tire Pressure Monitoring (TPM) Sensor - Description
DESCRIPTION
On vehicles equipped with Tire Pressure Monitoring (TPM), one tire pressure sensor (6) is mounted to each wheel (5) 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 315 MHz radio frequency. The 315 MHz sensors can be easily identified by a white outline oval (black center) insignia
(3) on the sensor body.
