Tire Pressure Sensor Replacement: Removal

WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Each tire pressure sensor contains a lithium anode battery that is not removable. The complete tire pressure sensor should be disposed of according to local battery disposal guidelines or requirements. An improperly disposed of battery can be harmful to the environment.
  1. Raise and support the vehicle (see LIFT AND SUPPORT POINTS ).
  2. Remove the wheel with the faulty tire pressure sensor.
  3. Remove the tire valve stem cap and the valve stem core, and let the tire deflate.
  4. Remove any balance weights, and then break the bead loose from the wheel with a commercially available tire changer (A).
    NOTE: Note these items to avoid damaging the tire pressure sensor:
    • Do the outside of the wheel first.
    • Position the wheel as shown so the valve stem (B) is 90 degrees from the bead breaker (C) as shown.
    • Do not position the bead breaker of the tire changer too close to the rim.

  5. Position the wheel so the tire machine (A) and tire iron (B) are next to the valve stem (C) and will move away from it when the machine starts. Then remove the tire from the wheel.

  6. Remove the valve stem nut (A) and the washer (B), then remove the tire pressure sensor with valve stem (C) from the wheel.

  7. Remove and replace the valve stem grommet (A), from the tire pressure sensor (B).
NOTE:
  • The valve stem grommet might stay in the wheel; make sure you remove it.
  • Always use a new valve stem grommet whenever the tire pressure sensor has been removed from the wheel. When only removing a tire from the wheel, or when replacing the tire.
