Tire Pressure Monitoring (TPM) Sensor - Removal

REMOVAL

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.

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 reuse. Do not substitute a regular valve stem cap in its place.

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.





1. Remove the tire/wheel from the vehicle.
2. Remove the balancing weights from the wheel (1).
3. Remove the cap from the valve stem (2).
4. Using the appropriate tool, remove the core (4) from the valve stem (2).
5. Allow 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 transmitter when servicing the tire.

6. Remove the nut (1) mounting the valve stem (4) of the pressure sensor/transmitter to the wheel (2). Drop sensor/transmitter into the tire (3).

CAUTION: When breaking the top and bottom bead of the tire off the wheel, care must be used so the bead breaking mechanism on the tire changer does not damage the wheel. This includes the surface of the wheel flange on the inside of the wheel.

7. Using the tire changer manufacturer's procedure, first break down the upper bead of the tire. Then break down the bottom bead of the tire.

CAUTION: When dismounting the upper tire bead from the wheel, the proper procedure must be used. Not using the proper procedure will result in damage to the wheel and tire.





8. Dismount the upper bead of the tire (1) from the wheel (2). The upper bead must be fully dismounted from the wheel to remove the tire pressure transmitter from the inside of the tire. The bottom bead of the tire does not need to be removed from the wheel.
9. Pull upward on the tire (1). Reach inside the tire and remove the pressure sensor/transmitter (3).
