Tire Low Pressure Sensor: Removal
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Use only special tool 204-354 anytime tire pressures are measured to be sure that accurate values are obtained.
CAUTION:
Place the air chuck straight on the valve stem to inflate the tire. Do not cock the air chuck during the inflation cycle. Doing so can damage the valve stem and cause air leaks.
CAUTION:
Ford recommends using a round head air chuck on tire pressure sensors; it is not recommended to use air chucks with long shanks. Doing so can cause tire pressure sensor valve stem damage and loss of tire pressure.
- Remove the wheel and tire assembly. For additional information, refer to WHEEL AND TIRE - FRONT or WHEEL AND TIRE - REAR .
- 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 the tire.
- Remove and discard the grommet from the tire pressure sensor.
CAUTION:
If the valve stem core has been removed from the valve stem, re-install 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:
Do not remove the valve stem core to relieve the 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.
