Cummins ISB CM850 (2003-06) Fault Code: 1142 PID: SID 3 SPN: 653 FMI: 7 Injector Solenoid Driver Cylinder 3 – Mechanical System Not Responding Properly or Out of Adjustment. Unintended fueling detected in cylinder number 3. 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...

Cummins ISB CM850 (2003-06) Fault Code: 1144 PID: SID 5 SPN: 655 FMI: 7 Injector Solenoid Driver Cylinder 5 – Mechanical System Not Responding Properly or Out of Adjustment. Unintended fueling detected in cylinder Number 5. This fault code can be caused by a failed or damaged injector causing continuous injection. If an injector nozzle is fractured or stuck open, continuous fueling will occur in that cylinder. If this condition occurs, an audible engine knock will be present, and the engine may stall and not start. In addition, low fuel rail pressure and excessive exhaust smoke will be present during...

Cummins ISB CM850 (2003-06) Fault Code: 1145 PID: SID 6 SPN: 656 FMI: 7 Injector Solenoid Driver Cylinder 6 – Mechanical System Not Responding Properly or Out of Adjustment. Unintended fueling detected in cylinder Number 6. This fault code can be caused by a failed or damaged injector causing continuous injection. If an injector nozzle is fractured or stuck open, continuous fueling will occur in that cylinder. If this condition occurs, an audible engine knock will be present, and the engine may stall and not start. In addition, low fuel rail pressure and excessive exhaust smoke will be present during...

Cummins ISB CM850 (2003-06) Fault Code: 115 PID: 190 SPN: 612 FMI: 2 Engine Magnetic Crankshaft Speed/Position Lost Both of Two Signal – Data Erratic, Intermittent, or Incorrect. The ECM has detected that the primary engine speed sensor and the backup engine speed sensor signals are reversed. The main engine speed sensor (crankshaft position sensor) and the backup engine speed sensor (camshaft position sensor) are located in close proximity to one another. The same sensor is used in both locations. (Connector key is the same.) A P-clip on the engine wiring harness prohibits the harness connectors from being connected to...
