Tire Pressure Sensor: Service and Repair
TIRE PRESSURE SENSOR
REMOVAL
1. Remove tire and wheel assembly from vehicle.
CAUTION: 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 reuse. Do not substitute a regular valve stem cap in its place.
CAUTION: 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 with a valve stem core made of a different material. This is required to prevent corrosion in the valve stem caused
by the different metals.
2. Dismount tire from wheel following tire changer manufacturers instructions while paying special attention to the following to avoid damaging the
pressure sensor:
a. When breaking the tire bead loose from the wheel rim, avoid using the Bead Breaker in the area of the sensor. That includes both front and
rear beads of the tire.
b. When preparing to dismount the tire from the wheel, carefully insert the mounting/dismounting tool at the valve stem ± 10° (Fig. 20), then
proceed to dismount the tire from the wheel. Use this process on both the upper and lower tire beads.
