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 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 25% 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.
Detroit DD16 GHG14 (2014-16) 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 compenstation pressure harness/connector.
