Tire Pressure Monitoring Sensor


• The cap used on this valve stem contains an O-ring seal to prevent contamination and moisture from entering the valve stem. Retain this valve stem cap for reuse. Do not substitute a regular valve stem cap in its place.

• The valve stem used on this vehicle is made of aluminum and the core is nickel plated brass. The original valve stem core must be reinstalled and not substituted with a valve stem core made of a different material. This is required to prevent corrosion in the valve stem caused by the different metals.

Special tools, testers and auxiliary items required

• Tire Pressure Monitor System Diagnostic Tool (J-49225)

Removing

- Raise and support vehicle.






- Remove wheel mounting nuts (3), then tire and wheel assembly (1).






- Dismount tire from wheel following tire changer manufacturers instructions while paying special attention to the following to avoid damaging the pressure sensor:

- When breaking the tire bead loose from the wheel rim, avoid using the bead breaker in the area of the sensor. That includes both front and rear beads of the tire.

- When preparing to dismount the tire from the wheel, carefully insert the mounting/dismounting tool at the valve stem ± 10°, then proceed to dismount the tire from the wheel. Use this process on both the upper and lower tire beads.






- Remove sensor nut (3) retaining sensor to wheel. While removing nut, hold pressure against rear of metal valve stem to keep valve stem from pushing rearward, damaging antenna strap.

- Remove sensor (1) from wheel (2).

• Before reinstalling an existing tire pressure sensor, replace seal (2) and metal washer (1) at base of sensor valve stem (6) to ensure proper sealing.

Installing


To avoid damaging sensor antenna strap (1), hold pressure against rear of metal valve stem (2) while sensor is inserted through wheel mounting hole and nut is installed.

- Wipe area clean around sensor/valve stem mounting hole in wheel (2). Make sure surface of wheel is not damaged.






- Insert sensor (1) through wheel (2) as shown keeping pressure against rear of metal valve stem - arrow -. Potted side of sensor is to be positioned toward wheel. Do not attempt to mount sensor otherwise, damage may occur.

- Install sensor nut (with pressed-in washer) (3) by hand.






• Before tightening sensor nut, push downward on sensor housing (2) in an attempt to make it flush with interior contour of wheel (1).

- While holding sensor in position, tighten sensor nut to 4.5 Nm (40 in lbs).


Over-torquing the sensor nut by as little as 12 Nm (106 in lbs) may result in sensor separation from the valve stem. Under this condition, the sensor may still function. However, the condition should be corrected immediately.

- Mount tire on wheel following tire changer manufacturers instructions, paying special attention to the following to avoid damaging tire pressure sensor:






- Rotating wheel tire changers - Once the wheel is mounted to the changer, position the sensor valve stem (2) approximately 210° from the head of the changer (located at 1) in a clockwise direction before rotating the wheel (also in a clockwise direction) to mount the tire. Use this procedure on both the upper and lower tire beads.






- Rotating tool tire changers - Position the wheel on the changer so that the sensor valve stem (1) is located approximately 210° clockwise from the installation end of the mounting/dismounting tool (2) once the tool is mounted for tire installation. Make sure the sensor is clear of the lower bead breaker area (3) to avoid damaging the sensor when the breaker rises. Rotate the tool (2) in a counterclockwise direction to mount the tire. Use this procedure on both the upper and lower tire beads.






- Adjust air pressure to that listed on tire inflation pressure label provided with vehicle (applied to driver side B-pillar). Make sure original style and color valve stem cap is securely installed to keep moisture out of sensor.

- Install tire and wheel assembly (1) on vehicle. Tighten wheel mounting nuts (3) to 135 Nm (100 ft lbs).

- Lower vehicle.

- Perform one of the following to make the system learn the new sensor ID.

- Use the Tire Pressure Monitor System Diagnostic Tool (J-49225) , with the scan tool to program the WIN with the tire pressure sensor ID. This is part of the TPM Diagnostic Verification Test.

- Once the vehicle has remained stationary for more than 20 minutes, drive vehicle for a minimum of 10 minutes while maintaining a continuous speed above 15 mph (24 km/h). During this time, the system will learn the new sensor ID. This is part of the TPM Diagnostic Verification Test.

• If a sensor cannot be trained, refer to appropriate diagnostic information.
