Model: 2006 V6 TUCSON
Subject: TPMS SENSOR REMOVAL AND INSTALLATION SERVICE PROCEDURES
DESCRIPTION:
2006 Model Year 2.7L V-6 Tucson vehicles are equipped with a Tire Pressure Monitoring System (TPMS) This bulletin describes TPMS sensor removal and installation service procedures.
NOTE: For additional information, refer to the 2006 Tucson Shop Manual and Technical Service Bulletin (TSB): 05-50-013.
TPMS SENSOR SERVICE GUIDELINES:
Review the decision flowchart prior to sensor removal.
SENSOR REMOVAL PROCEDURE:
1. Deflate the tire and remove balance wheel weights.
2. Start tire dismounting approximately 180� away from the valve position. During tire dismounting, tire must not apply any pressure onto the sensor housing. The tire dismounting process should end near the valve stem, without touching it.
NOTE: Do not set the bead breaker too deep, and avoid tire tool contact with the TPMS sensor (two photos show the bead breaking operation).
3. Separate the tire from the rim without damaging the TPMS sensor.
4. Unscrew the nut using an 11 mm socket.
5. Discard the nut immediately.
6. Remove the sensor and valve assembly from the rim.
7. Unscrew the valve stem from the screw and discard both valve stem and screw.
NOTE: There is a break away feature inside the nut which is used to set the torque on the screw. This is a one time use feature and, therefore, the nut and the valve stem cannot be reused.
PARTS INFORMATION:
SENSOR ASSEMBLY AND INSTALLATION PROCEDURE:
1. Insert the screw into the slotted hole of the sensor. Make sure that the flats of the square on the screw fit inside the edges of the hole.
2. While holding the screw in the slotted hole with a finger, assemble the valve to the screw, and turn the valve 3 to 4 full rotations.
NOTE: Make sure that the square part of the screw is well seated in the sensor's slotted hole, and the valve is free to move up and down the full length of the slot as shown.
3. Slide the loosely assembled valve assembly through the valve hole of the rim. Maintain the sensor's feet against the rim and the rubber grommet against the sealing surface.
4. Start screwing the nut using a deep 11 mm socket. The head of the screw will soon have a tight contact with the sensor housing. Continue to screw the nut until the thin flange breaks at approximately 20 lb-in (2.2 Nm). Now finish torquing the nut to specification.
Tightening torque specification
30-40 lb-in (3.5-4.5 Nm).
NOTE:
- Increase the torque smoothly to achieve a clean break of the stop.
- Do not exceed the allowed torque limit (max torque = 40 lb-in).
- Do not use electric or pneumatic tools.
5. Check that the valve is firmly attached to the rim and that the sensor is firmly attached to the valve.
WARNING: A new nut and valve assembly must be used if a sensor installation procedure is repeated for any reason.
6. Install the tire on the rim without damaging the TPMS sensor.
WARRANTY INFORMATION:
Normal warranty procedure apply.
