Cummins ISB CM850 (2003-06) Fault Code: 2381 PID: SPN: 2795 FMI: 4 Turbocharger position sensor circuit – shorted high. High signal voltage detected at the turbocharger position sensor circuit.
Cummins ISB CM850 (2003-06) Fault Code: 2381 PID: SPN: 2795 FMI: 4 Turbocharger position sensor circuit – shorted high. High signal voltage detected at the turbocharger position sensor circuit.
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:
1)Open return circuit in the harness, connectors, or sensor
2)Signal shorted to sensor supply or battery voltage
3)Failed ECM
4)Failed VGT position sensor.
Possible repairs:
1)Replace the turbocharger position sensor.
2)Repair or replace the engine harness.
3)Replace the ECM.
