Tire Pressure Monitoring System (TPM): Notes
WARNING: This page is about a different car, the 2003 Dodge Grand Caravan, 2003 Dodge Caravan, 2003 Chrysler Voyager, and 2003 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
If equipped with the Tire Pressure Monitoring System (TPM), each of the vehicles four wheels will have a valve stem with a pressure sensor and radio transmitter built in. Signals from the tire pressure Sensor/Transmitters are received and interpreted by the Electronic Vehicle Information Center (EVIC).
A Sensor/Transmitter in a mounted wheel will broadcast its detected pressure once per minute when the vehicle is moving faster than 32 km/h (20 mph). Each Sensor/Transmitter's broadcast is uniquely coded so that the EVIC can determine the location.
