Tire Pressure Sensor Grommet Replacement

Tire Pressure Sensor Grommet Replacement

Removal Procedure
1. Raise the vehicle on a suitable support. Refer to Vehicle Lifting.
2. Remove the tire/wheel assembly from the vehicle.

Important: Before the tire is removed from the wheel, care must be given with the following items to avoid the 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 materiel.
^ When using the tire machine to separate the tire bead from the wheel, position the bead breaking fixture 90 degrees from the valve stem.
^ When removing the tire from the wheel, maintain a tolerance between the tire machine fixture, or irons, tire bead and the sensor.

3. Remove the tire from the wheel.





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.

4. Remove the tire pressure sensor nut.
5. Remove the sensor from the wheel.
6. Remove the grommet from the sensors valve stem.

Installation Procedure
1. Clean any dirt or debris from the grommet sealing areas.
2. Install the grommet on the sensors valve stem.





3. Insert the sensor through the wheel hole with the air passage facing away from the wheel.

Notice: Refer to Fastener Notice in Service Precautions.

4. Install the sensor nut and position the sensor body parallel to the inside wheel surface while torquing.
^ For domestic vehicles tighten the sensor nut to 7 Nm (62 inch lbs.).
^ For export vehicles tighten the sensor nut to 12 Nm (106 inch lbs.).

Important: To avoid tire pressure sensor damage when mounting the tire back on the wheel maintain a tolerance between the tire machine, or irons, tire bead and the sensor.

5. Install the tire on the wheel.
6. Install the tire/wheel assembly on the vehicle.
7. Lower the vehicle.
