Description: Dozer FLP Sensors Failed Self Test
Troubleshooting:
DESCRIPTION:
This fault code runs a system check that closes the fuel cutoff valve and opens the dozer valve
in the dozer block, then compares the fuel compensation sensor to the dozer line pressure
sensor. If both pressure sensors are not within 48 kPa (7psi) for a count of 4 seconds, the code
becomes active.
MONITORED PARAMETER:
Doser fuel line pressure.
TYPICAL ENABLING CONDITIONS:
Dosing enabled
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Continuous when enabling conditions met.
TYPCIAL DURATION:
1 minute
DASH LAMPS:
1. MIL
2. CEL
3. DPF Inhibit
ENGINE REACTION:
10% Derate
VERIFICATION:
Parked regeneration
POSSIBLE CAUSES:
1. Faulty Hydrocarbon Doser Block.
2. External fuel leaks in the HC doser block.
3. Needs parked regen.
4. Faulty Fuel Doser injection valve.

Description: Fuel Cut-Off Valve Pressure Not Plausible
Troubleshooting:
DESCRIPTION:
Fuel Cut-off valve pressure not plausible.
MONITORED PARAMETER:
Hydrocarbon (HC) doser fuel compensation pressure.
TYPICAL ENABLING CONDITIONS:
Dosing enabled
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Continuous when enabling conditions met.
TYPCIAL DURATION:
One minute
DASH LAMPS:
1. MIL
2. CEL
ENGINE REACTION:
Derate 25%
VERIFICATION:
Parked regeneration
POSSIBLE CAUSES:
1. External fuel leaks in the HC Doser Block assembly and Fuel Doser Injector Valve fuel lines.
2. Faulty Hydrocarbon Fuel Doser Block
