DESCRIPTION:This fault code sets when the motor control module (MCM) detects that the hydrocarbon (HC) doser fuel line pressure (FLP) sensor circuit is failed low. MONITORED PARAMETER:Hydrocarbon (HC) doser fuel line 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 4077-3 and 94-3 are present, repair the open between pin 104 of the ECM 120-pin connector and pin 4 (or pin 2 on DD15 engines) of the hydrocarbon doser fuel lines pressure sensors.2. Failed fuel line pressure (FLP) sensor.3. Wiring between the...

NOTE: This fault indicates the vehicle contains incompatible motor control module (MCM) or the aftertreatment control module (ACM) software versions. Clear the fault, and if fault again becomes active, MCM/ACM software must be reprogrammed to the correct level. If fault does not become active, release the vehicle. NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: The engine ECMs need to be reprogrammed to the correct levels. Detroit DD13 EPA10 (2010-13) Fault Code: SPN 4077 FMI 14 (MCM) Hydrocarbon Doser Fuel Line Pressure Failed Self – Test Detroit DD13 EPA10 (2010-13) Fault Code: SPN 4077...

DESCRIPTION:EGR differential pressure too high (Low Box). MONITORED PARAMETER:EGR delta pressure sensor. TYPICAL ENABLING CONDITIONS:1. Start with engine off.2. Idle speed less than 900 rpm.3. Coolant temperature greater than 65°C (149°F).4. DPF zone 0. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Once per drive cycle. TYPICAL DURATION:20 DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:Shut engine off if it is running, start engine and warm it up by driving the vehicle such than coolant temperature is greater than 65°C (149°F), then let vehicle idle for greater than five minutes at less than 900 rpm. PROBABLE CAUSES:1. EGR delta p sensor failure.2. EGR delta p...

DESCRIPTION:This fault code sets when EGR delta pressure is too low at high speeds and loads. MONITORED PARAMETER:EGR delta pressure sensor. TYPICAL ENABLING CONDITIONS:1. Engine running greater than five minutes.2. Engine speed 1100 to 1850 rpm.3. Engine torque 1400 to 2800 Nm (1033 to 2065 lb.-ft).4. Engine not in regeneration mode.5. Engine must be in steady-state mode.6. Intake manifold temperature greater than 0°C (32°F).7. Desired EGR position greater than 30%.8. Coolant temperature greater than 65°C (149°F).9. Ambient temperature greater than -8°C (17°F) ambient.10. Barometric pressure greater than 755 mbar (10.9 psi). MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:5 min DASH...

DESCRIPTION:This fault code sets when the motor control module (MCM) detects that there is EGR pressure when the engine is not running. MONITORED PARAMETER:EGR delta pressure. TYPICAL ENABLING CONDITIONS:Coolant temperature greater than 80°C (176°F) and ignition is cycled off for 10 seconds. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:15 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:1. Run the engine until the coolant temperature is greater than 80°C (176°F).2. Turn the ignition off for 15 seconds.3. Turn the ignition on as a recheck for the fault code. PROBABLE CAUSES:1. EGR delta p sensor failure.2. EGR delta...
