Cummins ISB CM850 (2003-06) Fault Code: 1139 PID: SID 1 SPN: 651 FMI: 7 Injector Solenoid Driver Cylinder 1 – Mechanical System Not Responding Properly or Out of Adjustment. Unintended fueling detected in cylinder number 1.
This fault code can be caused by a failed or damaged injector causing continuous injection into the cylinder. Progressive cylinder damage may occur if the engine is operated for an extended period of time with this condition. If a failed injector is found to be the cause of this fault code, the cylinder liner and piston must be inspected for progressive damage.
If an injector nozzle is fractured or stuck, continuous fueling will ocur in that cylinder. If this condition occurs, the engine will typically die and not start. There will be exhaust smoke during cranking and no fuel rail pressure will be developed during cranking. Fault Code 2215 will be active during cranking if this condition exists.
1)Replace the fuel injector.
Cummins ISB CM850 (2003-06) Fault Code: 1119 PID: 110 SPN: 110 FMI: 0 Engine Coolant Temperature – Data Valid But Above Normal Operating Range – Moderately Severe Level. Engine coolant temperature signal indicates engine coolant temperature is above engine protection warning limit.
Cummins ISB CM850 (2003-06) Fault Code: 1117 (Marine) PID: SID 251 SPN: 627 FMI: 2 Power Lost without Ignition Off – Data Erratic, Intermittent, or Incorrect. Supply voltage to the ECM fell below +6.2-VDC momentarily, or the ECM was not allowed to power down correctly (retain battery voltage for 30 seconds after key OFF).
Cummins ISB CM850 (2003-06) Fault Code: 1117 (Auto) PID: SID 251 SPN: 627 FMI: 2 Power Lost Without Ignition Off – Data Erratic, Intermittent, or Incorrect. Supply voltage to the ECM fell below 6.2-VDC momentarily, or the ECM was not allowed to power down correctly (retain battery voltage for 30 seconds after key OFF).
Cummins ISB CM850 (2003-06) Fault Code: 958 PID: 27 SPN: 2795 FMI: 2 VGT Position Sensor – Data erratic, intermittent, or incorrect. Intermittent variable geometry turbocharger (VGT) position information is being received by the electronic control module (ECM).
Cummins ISB CM850 (2003-06) Fault Code: 957 PID: 27 SPN: 27 FMI: 2 EGR Valve Position – Data erratic, intermittent, or incorrect. Intermittent EGR position information is being received by the electronic control module (ECM).
Cummins ISB CM850 (2003-06) Fault Code: 951 PID: 166 SPN: 166 FMI: 2 Cylinder power imbalance between cylinders. A power imbalance between cylinders was detected by the ECM.
