Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3480 FMI 1 (MCM) Hydrocarbon Doser Fuel Supply Pressure Abnormal
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. MIL
2. 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 leaking.
2. Low pressure fuel out of spec (10-65 psi).
3. Fuel compensation pressure sensor.
4. Perform parked regen.
