Tire Pressure Monitor Sensor
WARNING: This page is about a different car, the 2003 Chrysler 300M and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Do not use a standard valve stem cap or core in a tire pressure sensor. Always use the original equipment style sensor cap and core. Do not try to install a tire pressure sensor in a steel wheel or aftermarket wheel. Use only in original style factory wheels.
One tire pressure sensor is mounted to each wheel. See Fig 1 . 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 serviceable components are:
- Sensor-to-wheel grommet.
- Valve stem cap.
- Valve stem core.
Valve stem caps and cores are specifically designed for the tire pressure monitoring sensors. Although similar to standard valve stem caps and cores, they are different.
Tire pressure sensors are battery operated. They transmit tire pressure data once per minute at speeds above 20 MPH (32 KM/H) or up to once every hour when stationary (parked).
