Make: Detroit
Engine: DD15 GHG17 (2017 & Newer)
PID: N/A
SPN: 100
FMI: 3
Description: Engine Oil Pressure Sensor Circuit Failed High
Troubleshooting:
DESCRIPTION:
This fault sets when either short to voltage or open circuit on engine oil pressure (EOP) sensor
circuit are present
TYPICAL ENABLING CONDITIONS:
Always on
MONITOR SEQUENCE:
1. Key on
2. Engine running
EXECUTION FREQUENCEY:
Continuous when enabling conditions are met
TYPCIAL DURATION:
Two seconds
DASH LAMPS:
CEL
ENGINE REACTION:
None
VERIFICATION:
Check at engine operating temperature.
NOTE: If diagnostic leads to a mechanical (non-electrical) low oil pressure condition, all mains
and connecting rods should be inspected. Refer to section “Inspection of the main and
connecting rod bearings in chassis”.
POSSIBLE CAUSES:
1. Faulty wiring.
2. Faulty EOP sensor.

MONITORED PARAMETER:
Engine oil pressure.
TYPICAL ENABLING CONDITIONS:
Always enabled
MONITOR SEQUENCE:
1. Key on.
2. Engine running at speeds below 625 rpm.
EXECUTION FREQUENCEY:
Continuous when enabling conditions are met.
TYPCIAL DURATION:
Two seconds
DASH LAMPS:
CEL
ENGINE REACTION:
None, engine derate or engine shut down – calibration dependent.
VERIFICATION:
While the engine is at normal operating temperature, road test performing several
decelerations.
POSSIBLE CUASES:
1. Damaged pins.
2. Bent pins.
3. Spread pins.
4. Unseated pins.
5. Faulty wiring.
6. Faulty EOP sensor.

Description: Low Oil Pressure Derate
Troubleshooting:
DESCRIPTION:
This fault code sets when the engine power has been limited to prevent engine damage due to
a low oil pressure condition.
MONITORED PARAMETER:
Engine oil pressure.
TYPICAL ENABLING CONDITIONS:
Always on
MONITOR SEQUENCE:
1. Key on.
2. Engine running.
EXECUTION FREQUENCEY:
Continuous when enabling conditions are met.
TYPCIAL DURATION:
Two seconds
DASH LAMPS:
CEL
ENGINE REACTION:
Engine derate or engine shut down- calibration.
VERIFICATION:
Check at engine operating temperature.
POSSIBLE CAUSES:
1. Failed oil pressure sensor.
2. Initial start after oil maintenance.
3. Vehicle is parked on a steep incline.
4. Improper oil level.
5. Oil dilution.
6. Leaks in the oil suction manifold.
7. Leaks at the oil suction pipes.
8. Failed oil pump.
