Tire Pressure Sensor: Removal

  1. Raise vehicle on a suitable support. Remove tire/wheel assembly from vehicle.
  2. Dismount tire from wheel following tire changer manufacturer's instructions while paying special attention to the following to avoid damaging tire pressure sensor:
    • Place the sensor's cap and valve on a dry, clean surface after removal. The cap is aluminum and the valve is nickel-plated to prevent corrosion. DO NOT substitute a cap or valve made of any other material.
    • Position the bead breaking fixture 90 degrees from valve stem when separating tire bead from wheel.
    • Position the mounting/dismounting head so tire iron (or pry bar) can be inserted slightly clockwise of sensor body when prying tire bead up and over the mounting/dismounting head.
    • Using tire machine, rotate tire/wheel assembly clockwise when transferring the tire bead to the outside of the wheel rim.
    • Repeat items for inner bead.
  3. Remove TORX screw from the tire pressure sensor. See Fig 1.
  4. Pull screw and tire pressure sensor from the tire pressure valve stem.
  5. Remove the tire pressure valve stem from rim.
