Circuit Description

The turbocharger position sensor outputs a voltage signal to the electronic control module (ECM). The ECM converts this signal into a percentage value, 0 to 100 percent, indicating turbocharger position. A fully closed turbocharger is equivalent to 100 percent.

Component Location

The turbocharger position sensor is located on the VGT actuator assembly. Refer to Procedure 100-002 for a detailed component location view.

Shop Talk

The turbocharger position sensor shares supply and return wires in the engine harness with other sensors. Opens and shorts in the engine harness can cause multiple fault codes to be active. Possible causes of this fault include:

  • Signal circuit open or shorted to ground
  • Supply circuit open or shorted to ground
  • Sensor shorted to ground.

Refer to Troubleshooting Fault Code t05-2382
