Tire Pressure Indicator Sensor Replacement w/o WC2 or WC8

1. Raise the vehicle on a suitable support. Refer to Lifting and Jacking the Vehicle in General Information.
2. Remove the tire/wheel assembly from the vehicle. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.

Important: Before the tire is removed from the wheel, note the following items to avoid tire pressure sensor damage upon tire dismounting.

•	Place the sensors cap and valve on a dry clean surface after removal, the cap is aluminum and the valve is nickel plated to prevent corrosion and are not to be substituted with a cap or valve made of any other material.

•	When separating the tire bead from the wheel, position the bead breaking fixture 90 degrees from the valve stem.

•	Position the mounting/dismounting head so the tire iron, or pry bar can be Inserted slightly clockwise of the sensor body ensuring the tire iron, or pry bar does not interfere with the sensor body when prying the tire bead up and over the mounting/dismounting head.

•	Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the out side of the wheel rim.

•	Repeat items for inner bead.

3. Remove the tire from the wheel. Refer to Tire Mounting and Dismounting in Tires and Wheels.



4. Remove the tire pressure sensor nut.
5. Remove the sensor from the wheel.

1. Clean any dirt or debris from the sensor grommet sealing area of the wheel.



2. Insert the sensor in the valve stem hole with the air passage facing away from the wheel.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Install the sensor nut and position the sensor body parallel to the inside wheel surface while torquing.

Tighten

•	For domestic vehicles, tighten the nut to 7 N·m (62 lb in).

•	For export vehicles, tighten the nut to 12 N·m (106 lb in).

Important: Before installing the tire on the wheel, note the following items to avoid tire pressure sensor damage upon tire mounting.

•	Position the mounting/dismounting head 180 degrees from the valve stem.

•	Position the bead transition area 45 degrees counter clockwise of the valve stem.

•	Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the inside of the wheel rim.

•	Repeat items for outer bead.

4. Install the tire on the wheel. Refer to Tire Mounting and Dismounting in Tires and Wheels.
5. Install the tire/wheel assembly on the vehicle. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
6. Lower the vehicle.
7. Learn the tire pressure sensors. Refer to Tire Pressure Sensor Learn .

Tire Pressure Indicator Sensor Replacement w/WC2 or WC8

The tire pressure sensor is secured to the tire insert ring inside the wheel/tire assembly and is not serviced separately from the wheel/tire assembly. Any sensor that has been diagnosed to be malfunctioning requires the replacement of the wheel/tire assembly. Refer to Tire and Wheel Removal and Installation .
