REMOVAL PROCEDURE




1. Remove the intake manifold cover.
2. Disconnect the turbocharger vane position sensor electrical connector.

IMPORTANT: Note wire routing prior to removal.

3. Remove the turbocharger vane position sensor connector from the bracket.
4. Remove the turbocharger vane position sensor from the turbocharger.

INSTALLATION PROCEDURE




1. Install the turbocharger vane position sensor to the turbocharger.

NOTE: Refer to Fastener Notice in Service Precautions.

Tighten the sensor to 28 N.m (21 lb ft).

2. Install the turbocharger vane position sensor connector to the bracket.
3. Connect the turbocharger vane position sensor electrical connector.
4. Install the thermal reflective shield/tape, refer to the following procedure.

THERMAL REFLECTIVE SHIELD/TAPE INSTALLATION

IMPORTANT:
- Ensure outside surface of sensor body is clean and oil-free prior to beginning the installation procedure. If sensor body surface is oily, use a mild degreaser in order to remove the oil from the surface. Ensure degreased surface is dry prior to beginning the installation.
- The thermal reflective shield and tie strap are to be installed over the vane position sensor AFTER the sensor is installed and torqued in the turbo center housing. Graphics below show the sensor prior to the installation process for clarity purposes only.




1. Peel off the protective backing from the back side of the thermal reflective shield/tape.




2. With the sticky side of the shield/tape applied against the sensor body, align the bottom edge of the shield/tape with the bottom edge of the hex, and begin wrapping the sensor.




3. Completely wrap the shield/tape around the sensor.




4. Tuck the top of the shield/tape under the head of the brass cable crimp sleeve all around, allowing the shield/tape to fold over and overlap itself at the top.




5. The top of the shield/tape is now shown tucked under the head of the brass cable crimp sleeve all around.




6. Wrap the tie strap around the necked porting of the sensor body just above the hex. Insert the end of the strap in the buckle and tighten by pulling the end with needle nose pliers.




7. Bend the end of the tie strap 180 degrees over the top of the buckle.




8. Cut off the tie strap using side cutters so that the cut end will lie approximately over the center of the buckle. Push down the end of the tie strap over the buckle in order to minimize protrusion of the cut end or any sharp edges.




9. Finished installation is shown.
10. Install the intake manifold cover.
11. Perform the turbocharger learn procedure. Refer to Turbocharger Learn Procedure.
