Tire Pressure Sensor: Service and Repair
Tire Low Pressure SensorRemoval
NOTE: It is strongly recommended that a new tire low pressure sensor O-ring seal, washer, nut, valve core and cap are installed each time a tire is removed and installed. The O-ring seal, washer, nut, valve core and cap must be replaced if the tire low pressure sensor is removed. Removal of the tire low pressure sensor retaining nut must be regarded as tire low pressure sensor removal. The tire low pressure sensor valve cap must always be in place except when inflating, releasing pressure or checking pressure.
1. Remove the wheel and tire.
2. CAUTION: Make sure the tire bead is broken from the wheel rim 180 degrees from the tire low pressure sensor. Failure to follow this instruction may result in damage to the tire low pressure sensor.
Remove the tire.
3. CAUTION: Make sure you do not push on the tire low pressure sensor valve. Failure to follow this instruction may result in damage to the valve.
Remove the tire low pressure sensor.
^ Remove and discard the tire low pressure sensor retaining nut, valve core, valve cap, O-ring seal and washer.
Installation
1. CAUTION: The base of the valve stem must be held whilst pushing on the new seal and washer. Failure to follow this instruction may result in damage to the tire low pressure sensor.
NOTE: Make sure that the washer and O-ring seal are installed correctly. The flat face of washer must be seated against the sensor housing. The taper of O-ring seal points towards the wheel.
Install a new washer and O-ring seal.
^ Install a new valve core and valve cap.
2. CAUTION: Make sure solvents or cleaning agents of any type are not used to clean the tire low pressure sensor. Failure to follow this instruction may result in damage to the tire low pressure sensor.
NOTE: If the tire low pressure sensor is replaced on a road wheel, the new tire low pressure sensor identification code will be learnt when the vehicle is first driven. If a new tire low pressure sensor is fitted to the spare wheel the identification code for that tire low pressure sensor must be programmed into the tire pressure monitoring system module. The identification code is printed on the casing of each tire low pressure sensor and is prefixed with I D.
Install the tire low pressure sensor.
^ Support the base of the valve stem when installing the tire low pressure sensor.
^ Hold the tire low pressure sensor against the wheel rim when tightening the retaining nut.
^ Install a new tire low pressure sensor retaining nut.
^ Tighten the nut to 8 Nm.
3. CAUTION: Make sure no damage occurs to the tire low pressure sensor.
Install the tire and balance the wheel.
4. Install the wheel and tire.
