Detroit DD13 EPA10 (2010-13) Fault Code: SPN 4257 FMI 4 (MCM) Injector Amplifier Control Valve Cylinder 1, 2, 3 Shorted to Ground
Posted by Diezel 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 DD13 EPA10 (2010-13) Fault Code: SPN 4334 FMI 17 (ACM) Diesel Exhaust Fluid (DEF) Purge Pressure High
Posted by Diezel Solutions on
DESCRIPTION:Diesel exhaust fluid (DEF) purge pressure high. MONITORED PARAMETER:Diesel exhaust fluid (DEF) purge pressure. TYPICAL ENABLING CONDITIONS:1. Engine idle 1 minute.2. Engine off. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:30 counts DASH LAMPS:MIL VERIFICATION:SCR quantity test. NOTE: After repair is complete, fault must be cleared using the diagnostic service tool. PROBABLE CAUSES:1. DEF pressure sensor failure.2. DEF pressure sensor connector/harness.3. Check air line routing for the Pressure Limiting Valve (PLV), DEF pump, and metering unit for kinks/blockage.4. DEF return line blocked/kinked.5. DEF nozzle failure.6. DEF nozzle supply line blocked/kinked. Detroit DD13 EPA10 (2010-13) Fault Code: SPN 4334...
