Detroit DD16 GHG14 (2014-16) 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...
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3480 FMI 14 (MCM) Hydrocarbon Doser Fuel Line Pressure Sensor – Failed Self Test
Posted by PerDiezel Solutions on
DESCRIPTION:Hydrocarbon (HC) doser fuel line pressure (FLP) sensors-failed self test. 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:Derate 10% VERIFICATION:Parked regeneration PROBABLE CAUSES:1. Replace the fuel compensation pressure sensor.2. Perform stationary regen.
Detroit DD16 GHG14 (2014-16) 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 DD16 GHG14 (2014-16) 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 Hydrocabon (HC) doser block assy and associated fuel lines for leaks.2. Perform parked regen.
Detroit DD16 GHG14 (2014-16) 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 valuve fuel lines for external leaks.2. Replace the fuel compensation sesor (FCP).3. Perform a parked regen.
