Intrepid V6-2.7L VIN R (2003)
Tire Pressure Module: Description and Operation
TIRE PRESSURE MONITORING (TPM)
Some versions of this vehicle are equipped with a Tire Pressure Monitoring (TPM) system. It monitors air pressure in all five tires (includes full-size
There is a sensor (transmitter) in each of the vehicle's five wheels. The system alerts the driver when tire pressure falls outside predetermined
thresholds (pressure too low or too high). A message is then displayed on the Electronic Vehicle Information Center (EVIC) located in the overhead
console. Tire air pressures in the four road wheels are displayed on the EVIC when chosen. Pressure in the spare tire, although monitored, is not
displayed on the EVIC.
The Tire Pressure Monitoring (TPM) system uses wireless technology to monitor tire air pressure levels. Sensors, mounted to each road wheel as part
of the valve stem, transmit tire pressure readings to a receiver located in the overhead console. These transmissions occur once every minute at speeds
over 20 mph (32 km/h). The tire pressure status is shown on the Electronic Vehicle Information Center (EVIC) display upon demand. The Tire
Pressure Monitoring system remains active even if it is not displayed in the EVIC.
If any road tire pressure has exceeded the low or high pressure threshold (refer to chart), the TPM system will display a message on the EVIC and
sound a chime. It will then go into the tire pressure display screen and flash the pressure value of the tire that is low or high. This will be displayed for
the rest of the ignition cycle, or until either the C/T, MENU, STEP or RESET button is pressed.
If a road tire is replaced by the spare, the TPM system will detect the swap automatically (after the ignition has been cycled) and display "SPARE
SWAP DETECTED" along with a chime (This could take up to 10 minutes with the vehicle speed above 20 mph (32 km/h).
NOTE: TPM thresholds have been established for the original tire size equipped on the vehicle.
