Tire Pressure Sensor: Service and Repair

Tire Pressure Sensor Replacement

Removal

1. Raise the vehicle, and support it with safety stands in the proper locations. Service and Repair

2. Remove the wheel with the faulty sensor.

3. Remove the tire valve stem cap and the valve stem core, and let the tire deflate.

4. Remove any balance weights, and then break the bead loose from the wheel with a commercially available tire changer (A).
Note these items to avoid damaging the tire pressure sensor:

- Do the outside of the wheel first.

- Position the wheel as shown so the valve stem (B) is 90 degrees from the bead breaker (C) as shown.

- Do not position the bead breaker of the tire changer too close to the rim.





5. Position the wheel so the tire machine (A) and tire iron (B) are next to the valve stem (C), and will move away from it when the machine starts. Then remove the tire from the wheel.






6. Remove the valve stem nut (A) and the washer (B), then remove the tire pressure sensor with the valve stem (C) from the wheel.
NOTE: Check the nut and the washer, if they have deterioration or damage, replace with new ones during reassembly.






7. Remove and discard the valve stem grommet (A) from the tire pressure sensor (B).
NOTE:

- The valve stem grommet might stay in the wheel; make sure you remove it.

- Always use a new valve stem grommet whenever the tire pressure sensor has been removed from the wheel. When only removing a tire from the wheel, replace the valve stem grommet if it is possible.





Installation

NOTE:

- Use only wheels that have a "TPMS" stamp (A) on the inside of the aluminum wheels, and the outside of the steel wheels.

- The vehicle may be equipped with one of the six types of wheels.





1. Before installing the tire pressure sensor, clean the mating surfaces on the sensor and the wheel.

2. Install the tire pressure sensor (A) and the washer (B) to the wheel (C), and tighten the valve stem nut (D) finger tight. Make sure the pressure sensor is resting on the wheel.
NOTE: Install the tire pressure sensor so that sensor housing surface (E) should not exceed protrusion (F) of wheel to prevent the sensor housing from being caught onto the bead of the tire when assembling the tire.

3. Tighten the valve stem nut to the specified torque while holding the tire pressure sensor.
NOTE:

- Do not use air or electric impact tools to tighten a valve stem nut.

- Do not twist the tire pressure sensor to adjust its position with the wheel, as this will damage or deform the valve stem grommet.









4. Lube the tire bead sparingly with a paste-type tire mounting lubricant, and position the wheel so the tire machine (A) and tire iron (B) are next to the valve stem (C) and will move away from it when the machine starts. Then install the tire onto the wheel.

5. With a dry air source, inflate the tire to 300 kPa (3.1 kgf/cm2, 44 psi) to seat the tire bead to the rim, then adjust the tire pressure, Service and Repair then install the valve stem cap.
NOTE: Make sure the tire bead is seated on both sides of the rim uniformly.

6. Check and adjust the wheel balance, then install the wheels on the vehicle.

7. Remove the jack stands, and lower the vehicle. Torque the wheel nuts to specification.

8. Connect the HDS, and memorize the pressure sensor IDs using the TPMS sensor initializer tool. Memorizing the Tire Pressure Sensor ID
