Detroit DD15 GHG14 (2014-16) Fault Code: SPN 1077 FMI 31 (MCM) Fuel Rail Pressure Deviation is Greater than 200 Bar for Eight Seconds
POSSIBLE CAUSES:
1. External fuel leakage between the high pressure pump and fuel injectors.
2. Pressure limiting valve (PLV) leakage (internal).
3. Fuel filter integrity (loose caps, plugged filters).
4. Fuel supply issues (fuel level, fuel aeration, leaking fuel lines, fuel restrictions).
5. Intermittent loss of engine speed signal .
6. High pressure pump internal failure.
7. Fuel injector (amplifier or needle) leakage.
8. Fuel contamination.
9. Rail pressure sensor.
10. Motor control module (MCM).
