Cummins ISB CM850 (2003-06) Fault Code: 135 (Marine) PID: 100 SPN: 100 FMI: 3 Oil Pressure Sensor Circuit – Voltage Above Normal, or Shorted to High Source. High signal voltage detected at the engine oil pressure circuit.
The engine oil pressure sensor is located on the left side of the engine block.
Possible causes:
1)Open return circuit in the harness, connectors, or sensor
2)Signal circuit shorted to sensor supply or battery voltage.
Possible repairs:
1)Replace the oil pressure sensor.
2)Replace the ECM.
3)Replace the engine harness.
