Tire Pressure Sensor: Removal
WARNING: This page is about a different car, the 2004 Mercury Mountaineer and 2004 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the wheel and tire assembly. For additional information, refer to WHEEL AND TIRE - FRONT or WHEEL AND TIRE - REAR .
- The following illustration and table indicates parts making up the tire pressure monitoring sensor assembly.
- With the valve stem at the 6 o'clock position, remove the sensor retaining nut and push the sensor by hand into the tire (with the cap on).
- Using a suitable tire machine, separate both beads of the tire from the wheel.
- Place the wheel and tire on the turntable of the tire machine, index-mark the valve stem and wheel weight positions, lubricate the bead of the tire and dismount the outside bead of the tire from the wheel.
- Remove the tire pressure sensor from inside the tire.
- Remove and discard the grommet from the tire pressure sensor.
CAUTION:
Make sure to install a new sensor grommet or an air leak can occur.
NOTE:
Do not remove the valve stem core to relieve the tire pressure.
CAUTION:
If the valve stem core has been removed from the valve stem, reinstall the original valve stem core. If the original valve stem core is damaged, a nickel-plated core must be installed. Failure to use a nickel-plated core will result in corrosion and the possible loss of tire pressure.
NOTE:
Release the tire pressure by removing the sensor retaining nut.
CAUTION:
Care should be taken not to damage the tire pressure sensor while separating the outside bead of tire from the wheel.
