DESCRIPTION:5V Sensor Supply Bank 2 circuit failed high.

MONITORED PARAMETER:Motor Control Module (MCM) 5V internal power supply.

TYPICAL ENABLING CONDITIONS:Always enabled

MONITOR SEQUENCE:None

EXECUTION FREQUENCY:Always enabled

TYPICAL DURATION:Two seconds

DASH LAMPS:1. MIL2. CEL

ENGINE REACTION:None

VERIFICATION:Engine Idle (1 minute).

NOTE: Disconnect one sensor at a time.

PROBABLE CAUSES:When code goes inactive, that is the sensor that has failed:1. Fuel line pressure sensor.2. Fuel compensation pressure sensor.3. Engine oil pressure sensor.4. Inlet manifold pressure/temperature sensor.5. DPF inlet pressure sensor.6. DPF outlet pressure sensor.7. Intake throttle valve.8. Camshaft position sensor.

NOTE: If none go inactive, disconnect the 31-pin connector on left side of the engine. If code goes inactive, replace the DPF pressure sensor.

NOTE: If you disconnect the 120-pin ECM connection and the code is still active, replace the MCM.
