Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3480 FMI 16 (MCM) High Hydrocarbon Doser Supply Pressure High
Posted by PerDiezel Solutions on
NOTE: The code occurs when the cut off is commanded to 100% and the compensation pressure is greater than 95 psi. NOTE: If there are any other fuel system codes or 3480-14 present, fix those first. PROBABLE CAUSES:1. Failed doser pressure control valve in the high pressure flange.2. Perform parked regen.
Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3480 FMI 2 (MCM) Hydrocarbon Doser Fuel Line Pressure Low
Posted by PerDiezel Solutions on
DESCRIPTION:Hydrocarbon (HC) doser fuel line pressure low. MONITORED PARAMETER: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 there are any other fuel system codes, 3480-14, 3480-31, 3480-1, or 4407-14 present, fix those first. PROBABLE CAUSES:1. Inspect the Hydrocarbon (HC) doser block assy and associated fuel lines for leaks.2. Perform parked regen.
Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3480 FMI 21 (MCM) Fuel Cut-Off Valve Pressure Not Plausible
Posted by PerDiezel Solutions on
DESCRIPTION:Fuel Cut-off Valve (FCV) pressure not plausible. MONITORED PARAMETER:Hydrocarbon (HC) doser fuel compensation 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 there are any other fuel codes present, fix those first. PROBABLE CAUSES:1. Inspect the HC doser block assy and fuel doser injector valve fuel lines for external leaks.2. Replace the fuel compensation sensor (FCP).3. Perform a parked regen.
Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3480 FMI 3 (MCM) Fuel Compensation Pressure Sensor Circuit Failed High
Posted by PerDiezel Solutions on
DESCRIPTION:Fuel compensation pressure (FCP) sensor circuit failed high. MONITORED PARAMETER:Fuel compensation 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 100-3, 4077-3, 3480-3 are also present, repair the wiring between pin 82 of the ECM connection and the engine oil pressure, fuel line, and fuel compensation pressure sensors.2. If 4407-3 or 3480-3 are present, repair the wiring between pin 104 of the ECM connection and the fuel line and fuel compensation pressure sensor.3. Fuel Compensation Pressure sensor.4. Fuel compensation pressure harness/connector.
