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 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.
