Detroit DD13 EPA07 (2007-09) Fault Code: SPN 4077 FMI 14 (MCM) Hydrocarbon Doser Fuel Line Pressure Failed Self – Test
Posted by PerDiezel Solutions on
DESCRIPTION:Hydrocarbon (HC) doser fuel line pressure failed self – test. MONITORED PARAMETER:Hydrocarbon (HC) doser fuel line pressure. TYPICAL ENABLING CONDITIONS:Dosing enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:One minute DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 10% VERIFICATION:Parked regeneration NOTE: If any fuel system faults present, fix those first. PROBABLE CAUSES:1. Inspect the hydrocarbon doser block assy and the fuel doser injector valve fuel lines for any leaks.2. Low fuel pressure.3. Failed hydrocarbon doser fuel injection valve.4. Perform parked regen.
Detroit DD13 EPA07 (2007-09) Fault Code: SPN 4077 FMI 3 (MCM) Doser Fuel Line Pressure Sensor Circuit Failed High
Posted by PerDiezel Solutions on
DESCRIPTION:This fault code sets when the motor control module (MCM) detects that the hydrocarbon (HC) doser fuel line pressure (FLP) sensor circuit is failed high. MONITORED PARAMETER:Hydrocarbon (HC) doser fuel line pressure sensor. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:Engine Idle: One minute. PROBABLE CAUSES:1. If 4077-3 and 94-3 are present, repair the open between pin 104 of the ECM 120-pin connector and pin 4 (or pin 2 on DD15 engines) of the hydrocarbon doser fuel lines pressure sensors.2. Failed fuel line pressure (FLP) sensor.3. Wiring between the...
