Grand Caravan V6-3.3L VIN R (2005)
The valve stem caps and cores used are specifically designed for the tire pressure monitoring sensors. Although similar to standard valve stem caps
and cores, they are different. The valve stem cap has a special seal inside to keep moisture and corrosion out. The valve stem core has a special nickel
coating to protect from corrosion.
OPERATION
The battery operated tire pressure sensors lay dormant (Park Mode), then wake and start transmitting (Drive Mode) when the vehicle first reaches
speeds over 15 mph (24 km/h). Once the wheels stop rotating for a period of approximately 20 minutes, the sensors shut down until again awaken.
Although not transmitting as when in Drive Mode, while in Park Mode, the sensors still transmit approximately once every 13 hours to let the receiver
know air pressure status at that time.
Using an RF signal, each sensor transmits tire pressure data approximately once every minute. Each sensor's (transmitter) broadcast is uniquely coded
so that the Sentry Key Remote Entry Module (SKREEM) can monitor the state of each of the sensors on the four rotating road wheels. The SKREEM
automatically learns and stores the sensor's ID while driving after a sensor has been replaced. There is no formal retraining procedure necessary.
