Cummins ISL CM850 (2003-06) Fault Code: 187 (Marine) PID: SID 232 SPN: 1080 FMI: 4 Sensor Supply 2 Circuit - Voltage Below Normal, or Shorted to Low Source. Low voltage detected at the sensor supply number 2 circuit.

Low voltage on the +5-VDC supply line can be caused by a short circuit to ground in a supply line, a short circuit between a supply line or a return line, a failed sensor, or a failed ECM power supply.

Possible repairs:

1)Replace the intake manifold pressure sensor.
2)Replace the rail fuel pressure sensor.
3)Repair or replace the engine harness.
4)Replace the ECM.
