Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3480 FMI 0 (MCM) Fuel Compensation Pressure High
Posted by PerDiezel Solutions on
DESCRIPTION:This fault will become active once the fuel compensation pressure reaches and stays above 599 kPa (87 psi) for GEN1 fuel system, or 799 kPa(116 psi) for GEN2 fuel system, for longer than 600 seconds during a driving regen, or 60 seconds during a parked regeneration with all conditions met. MONITORED PARAMETER: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:1. Derate 10%.2. DPF inhibit regeneration. VERIFICATION:Parked regeneration NOTE: If any other codes are active, fix those first. PROBABLE CAUSES:1. HC doser or fuel doser...
Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3480 FMI 1 (MCM) Hydrocarbon Doser Fuel Supply Pressure Abnormal
Posted by PerDiezel Solutions on
DESCRIPTION:This code sets when the motor control module (MCM) detects that the fuel compensation pressure is lower that 358 kPa (52 psi) for GEN1 and 399 kPa (58 psi) for GEN2 for 10 minutes when dosing is enabled. MONITORED PARAMETER:Hydrocarbon (HC) doser fuel line pressure sensor. TYPICAL ENABLING CONDITIONS:Dosing enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:1. Ten minutes for parked regeneration.2. One minute during driving regeneration. DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 10% VERIFICATION:Parked regeneration NOTE: If 3480-14 active, fix those first. PROBABLE CAUSES:1. HC doser or fuel doser injector valve fuel lines are blocked or...
