Tire Pressure Monitoring - Service Information: Description

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

The Tire Pressure Monitoring (TPM) system monitors air pressure in the four road tires (excludes spare). Pressure in the spare tire is not monitored. There are two systems available on this vehicle, a base and a premium. The base system does not specify how many tires are low or where they are located. The premium system does so.

TPM alerts the driver when tire pressure falls below predetermined thresholds. (Refer to TIRES/WHEELS/TIRE PRESSURE MONITORING - OPERATION)

The TPM systems are controlled by the Wireless Control Module (WCM), commonly referred to as the Sentry Key Remote Entry Module (SKREEM).

There is a sensor (transmitter) in each of the vehicle's four road wheels that operates on a 315 MHz radio frequency. Export vehicle sensors operate on a 433 MHz radio frequency.

If a vehicle is equipped with the premium TPM system, transponders located in three of the four wheel wells of the vehicle are used to provide the WCM with the location of the tire pressure sensors on the vehicle. The transponders are located in the left front, right front and right rear wheel wells.

An indicator lamp located in the instrument cluster and, if equipped with the premium TPM system, the Electronic Vehicle Information Center (EVIC) are used to communicate system information.

For further information, refer to the Owners Manual or the appropriate diagnostic information.
