Detroit DD13 EPA10 (2010-13) Fault Code: SPN 100 FMI 1 (CPC) Oil Pressure Very Low

DESCRIPTION:
Fault code sets when engine oil pressure is less than a calibrated threshold.

MONITORED PARAMETER:
Engine oil pressure.

TYPICAL ENABLING CONDITIONS:
Always on

MONITOR SEQUENCE:
1. Key on
2. Engine running

EXECUTION FREQUENCY:
Continuous when enabling conditions are met.

TYPICAL DURATION:
Two seconds

DASH LAMPS:
1. SEL
2. CEL

ENGINE REACTION:
1. None.
2. Engine derate or engine shut down.
3. Calibration dependent.

VERIFICATION:
Check at engine operating temperature.

NOTE: The Common Powertrain Controller (CPC) digital outputs have the same SPN as some Motor Control Module (MCM) faults.

NOTE: If 100-1 and 100-3 are both active, work on repairing 100-3 first.

NOTE: If 100-1 and 100-4 are both active, work on repairing 100-4 first.

PROBABLE CAUSES:
1. Low oil level, check system for leaks.
2. Oil level sensor connector/harness.
3. Oil level sensor.
4. Oil level pressure fluctuating.
5. High oil level, check for fuel or coolant entering oil system.
6. Oil pump suction pipe cracked or loose.
7. Oil pump drive and driven gear loose.
8. Faulty oil pressure relief valve.
