Installation Procedure

WARNING: This page is about a different car, the 2007 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
  1. Clean any dirt or debris from the grommet sealing area.

  2. Insert the sensor in the wheel hole with the air passage facing away from the wheel.
    3. NOTE: Replacement components must be the correct part number for the application. Components requiring the use of the thread locking compound, lubricants, corrosion inhibitors, or sealants are identified in the service procedure. Some replacement components may come with these coatings already applied. Do not use these coatings on components unless specified. These coatings can affect the final torque, which may affect the operation of the component. Use the correct torque specification when installing components in order to avoid damage.
  3. Install the sensor nut and position the sensor body parallel to the inside wheel surface while tightening.

    Tighten:  Tighten the sensor nut to 7 N.m (62 lb in).

    4. IMPORTANT: Before reinstalling the tire on the wheel, note the following items to avoid tire pressure sensor damage upon tire mounting.
    • Position the mounting/dismounting head 180 degrees from the valve stem.
    • Position the bead transition area 45 degrees counterclockwise of the valve stem.
    • Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the inside of the wheel rim.
    • Repeat items for the outer bead.
  4. Install the tire on the wheel. Refer to Tire Mounting and Dismounting .
    5. IMPORTANT: A service replacement tire pressure sensor is shipped in OFF mode. In this mode the sensors unique identification code cannot be learned into the antenna modules memory. The sensor must be taken out of OFF mode by spinning the tire/wheel assembly above 32 km/h (20 mph) in order to close the sensors internal roll switch for at least 10 seconds.
  5. Install the tire/wheel assembly on the vehicle. Refer to Tire and Wheel Removal and Installation .
  6. Lower the vehicle.
  7. Learn the tire pressure sensors. Refer to Tire Pressure Sensor Learn .
