Cummins ISB CM850 (2003-06) Fault Code: 151 (Auto) PID: 110 SPN: 110 FMI: 0 Engine Coolant Temperature – Data Valid but Above Normal Operational Range – Most Severe Level. Engine coolant temperature signal indicates engine coolant temperature above engine protection critical limit. This fault code indicates that coolant temperature has exceeded the engine protection limits for high coolant temperature. Possible repairs: 1)Refer to the Engine Coolant Temperature Above Normal symptom troubleshooting tree in Troubleshooting and Repair Manual, ISB (Common Rail Fuel System) Series Engine, Bulletin 4021272 . Cummins ISB CM850 (2003-06) Fault Code: 148 PID: 91 SPN: FMI: 0 Accelerator...

Cummins ISB CM850 (2003-06) Fault Code: 153 PID: 105 SPN: 105 FMI: 3 Intake Manifold Air Temperature Sensor Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at intake manifold air temperature circuit. The intake manifold air temperature sensor shares RETURN wires in the engine harness with other sensors. Opens and shorts in the engine harness can cause multiple fault codes to be active. Check active fault codes with multiple counts first. Possible causes: 1)Open return circuit in the harness, connectors, or sensor2)Open signal circuit or shorted to voltage source. The sensor return configuration for...
