Overview
| CODE | REASON | EFFECT |
| Fault Code: 2381 PID: SPN: 2795 FMI: 4/4 LAMP: Amber SRT: |
Turbocharger position sensor circuit – shorted high. High signal voltage detected at the turbocharger position sensor circuit. |
Possible low power. Power will be removed from the turbocharger actuator motor. Turbocharger will be open. |
 Turbocharger Position Sensor Circuit
|
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 the position of the turbocharger actuator. 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:
- Open return circuit in the harness, connectors, or sensor
- Signal shorted to sensor supply or battery voltage
- Failed ECM
- Failed VGT position sensor.
