Removal Procedure
1. Raise the vehicle on a suitable support. Refer to Vehicle Lifting.
2. Remove the tire/wheel assembly from the vehicle.
3. Remove the tire from the wheel.
Important: Before the tire is removed from the wheel, note the following items to avoid tire pressure sensor damage upon tire dismounting:
^
Place the sensors cap and valve on a dry clean surface after removal, the cap is aluminum and the valve is nickel plated to prevent corrosion
and are not to be substituted with a cap or valve made of any other material.
^
Position the bead breaking fixture 90 degrees from the valve stem when separating the tire bead from the wheel.
^
Position the mounting/dismounting head so the tire iron, or pry bar can be inserted slightly clockwise of the sensor body when prying the tire
bead up and over the mounting/dismounting head.
^
Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the outside of the wheel rim.
^
Repeat items for inner bead.
4. Remove the tire pressure sensor nut.
Important: If any tire sealant is noted upon tire dismounting, replace the sensor. Also remove all residual liquid sealant from the inside of the tire
and wheel surfaces.
5. Remove the sensor from the wheel hole.
6. Remove the sensor grommet from the valve stem.
Installation Procedure
1. Clean any dirt or debris from the grommet sealing areas.
2. Install the grommet on the sensor valve stem.
3. Insert the sensor in the wheel hole with the air passage facing away from the wheel.
