Detroit DD16 GHG14 (2014-16) Fault Code: SPN 4257 FMI 3 (MCM) Injector Amplifier Control Valve Cylinder 1, 2, 3 Shorted to Battery
Posted by PerDiezel Solutions on
DESCRIPTION:Injector amplifier control valve cylinder 1, 2, 3 shorted to battery. MONITORED PARAMETER:Injector amplifier control valve cylinder 1, 2, 3. TYPICAL ENABLING CONDITIONS:Fis_nop_act is greater than 1.85. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:Engine rpm 1400 – 1500: One minute. PROBABLE CAUSES:1. Short to power between pin 2 of the front fuel injector harness 14-pin connector and pin 4 of the 120-pin ECM connection.2. Short to power between pin 4 of the front fuel injector harness 14-pin connector and pin 4 of the 120-pin ECM connection.3. Short to...

Posted by PerDiezel Solutions on
DESCRIPTION:This code sets when the MCM detects that there is a short to ground on the circuits for the injector amplifier control valve on cylinders 1, 2 and or 3. MONITORED PARAMETER:Injector amplifier control valve cylinder 1, 2, 3. TYPICAL ENABLING CONDITIONS:Fuel injector system nozzle opening pressure reading greater than 1.85. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:Engine rpm 1400 – 1500: One minute. PROBABLE CAUSES:1. Connector outside the valve cover.2. Under valve cover fuel injector harness.3. Failed fuel injector #1, #2, or #3.4. Wiring between the valve...

Detroit DD16 GHG14 (2014-16) Fault Code: SPN 4331 FMI 16 (ACM) DEF Dosing Quantity High
Posted by PerDiezel Solutions on
NOTE: The fault indicates that the DEF pump speed is low compared to DEF quantity delivered. The CEL lamp will remain on until the fault is resolved. NOTE: If code 3364-xx present, fix that first. PROBABLE CAUSES:1. Check all DEF supply lines for damage or leaks.2. DEF tank is contaminated with gas, diesel, water, etc…3. Doser valve failure.4. DEF pump.5. DEF pump connection/harness.
