Detroit DD16 GHG14 (2014-16) Fault Code: SPN 411 FMI 0 (MCM) Exhaust Gas Recirculation Differential Pressure is Too High at Low Speeds and Loads
Posted by PerDiezel Solutions on
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...

Detroit DD16 GHG14 (2014-16) Fault Code: SPN 411 FMI 13 (MCM) EGR Delta Pressure Sensor Out of Calibration
Posted by PerDiezel Solutions on
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...
