Turbocharger Vane Position Sensor: Service and Repair

Turbocharger Vane Position Sensor Replacement

Removal Procedure




1. Remove the intake manifold cover.

Important: Note the routing of the turbocharger vane position sensor pigtail prior to removal.

2. Disconnect the engine wiring harness electrical connector (1) from the turbocharger vane position sensor electrical connector (2).




3. Remove the turbocharger vane position sensor electrical connector clips from the wiring harness bracket.
4. Remove the thermal reflective shield/tape from the vane position sensor, if required.
5. Remove the turbocharger vane position sensor from the turbocharger.

Installation Procedure






Notice: Refer to Fastener Notice.

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

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

2. Install the turbocharger vane position sensor electrical connector clips to the wiring harness bracket.




3. Connect the engine wiring harness electrical connector (1) to the turbocharger vane position sensor electrical connector (1).
4. Install the thermal reflective shield/tape, if required.

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 centerhousing. 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 needlenose 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.
