Detroit DD16 GHG14 (2014-16) Fault Code: SPN 411 FMI 4 (MCM) EGR Delta Pressure Sensor Circuit Failed Low
Posted by PerDiezel Solutions on
DESCRIPTION:This fault code sets when there is an open in the voltage supply circuit, an open or short to ground on the signal return circuit. MONITORED PARAMETER:EGR delta pressure sensor return signal. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:2 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:Engine Idle: One minute. PROBABLE CAUSES:1. EGR delta p sensor failure.2. EGR delta p connector/harness.3. EGR delta p pressure ports blocked.4. EGR valve failure.5. Inspect the EGR crossover tube and mixer pipe for excessive buildup. If excessive, replaced the EGR cooler.6. Inspect EGR system for leaks/damage/issues.

Detroit DD16 GHG14 (2014-16) Fault Code: SPN 4193 FMI 10 (MCM) Coolant Temperature Sensors Not Plausible
Posted by PerDiezel Solutions on
DESCRIPTION:Coolant temperature sensor not plausible. MONITORED PARAMETER:Coolant inlet temperature sensor. TYPICAL ENABLING CONDITIONS:1. Engine speed 500- 2500 rpm.2. Coolant temperature is greater than 11 vDC.3. Run engine greater than 60s. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Once per drive cycle. TYPICAL DURATION:30 DASH LAMPS:MIL VERIFICATION:1. Start Engine.2. Warm up such that coolant temperature is greater than 11 vDC and engine has been running for at least 1 minute.3. Bring engine to idle speed.4. Being certain that it is greater than 500 rpm. NOTE: If there are any cooling system faults or conditions, repair those first. PROBABLE CAUSES:1. Inlet coolant temperature sensor.2. Inlet coolant...
