Tire Pressure Sensor: Service and Repair

Tire Low Pressure Sensor
This is a "Trustmark Authoring Standards (TAS) Repair Procedure"
- TAS style procedures can be identified by steps that have no accompanying step text and the magenta color of the electrical connectors and fasteners such as nuts, bolts, clamps or clips.
- TAS removal and installation procedures use a sequence of color illustrations to indicate the order to be followed when removing/disassembling or installing/assembling a component.
- Many of the TAS procedures will have the installation information within the removal steps.
- The TAS color illustrations use a variety of symbols to indicate important details of the procedures. It is important to understand these symbols in order to properly used the TAS procedures.
Refer to How to Use TAS Procedures and TAS Symbol Glossary at Vehicle | Description and Operation for additional information on these TAS procedures.

Removal

WARNING: The valve seal and steel washer must be replaced each time a tire is changed to avoid seal failure. The seal and washer must be replaced if the sensor is removed. Removal of the sensor retaining nut must be regarded as sensor removal. The valve cap must always be in place except when inflating, releasing or checking pressure.

NOTE:
If the sensor is replaced on a 'running' wheel, the new sensor identification will be learned when the vehicle is first driven. If a new sensor is installed to the spare wheel, the identification for that sensor must be programmed into the tire pressure monitoring system (TPMS) module using Land Rover approved diagnostic equipment. The identification code is provided on a label with the complete assembly and is also printed on the casing of each sensor.

WARNING: Make sure to support the vehicle with axle stands.
1 Raise and support the vehicle.
2 Remove the wheel and tire.

3 Remove the tire from the wheel.




Remove and discard the nut.
Release and withdraw the sensor along the valve axis.




4 Remove and discard the seal and washer.
