Tire Pressure Sensor: Service and Repair
Removal and Installation
REMOVAL - TIRE PRESSURE SENSOR/TRANSMITTER
1. Remove the tire/wheel from the vehicle.
CAUTION: When removing the stick on balancing weights from the wheel, do not use an abrasive cleaner or a cleaner which will damage the
protective finish on the wheel.
2. Remove the balancing weights from the wheel.
NOTE: The cap used on this valve stem contains an O-ring seal to prevent contamination and moisture from entering the valve stem. Retain this valve
stem cap for re-use. Do not substitute a regular valve stem cap in its place.
3. Remove the cap from the valve stem.
NOTE: The valve stem used on this vehicle is made of aluminum and the core is nickel plated brass. The original valve stem core must be reinstalled
and not substituted for a valve stem core made of a different material. This is required to prevent corrosion in the valve stem caused by the different
metals.
4. Using the appropriate tool, remove the core from the valve stem.
5. Let the tire fully deflate.
CAUTION: The pressure transmitter must be removed from the wheel and dropped into the tire prior to breaking the bead and dismounting the tire.
Failure to do this will greatly increase the risk of damaging the pressure transducer when servicing the tire.
