2. CEL
ENGINE REACTION:
Derate 25%
VERIFICATION:
Engine idle (one minute).
POSSIBLE CAUSES:
1. External fuel leakage between the high pressure pump and fuel injectors.
2. Pressure limiting valve 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).
