Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3031 FMI 4 (ACM) Diesel Exhaust Fluid Tank Temperature Sensor Circuit Failed Low
Posted by PerDiezel Solutions on
DESCRIPTION:Diesel exhaust fluid (DEF) tank temperature sensor circuit failed low. MONITORED PARAMETER:DEF tank temperature sensor. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:25% Derate. After Four hours, engine will be idled after ignition key cycle. VERIFICATION:Engine Idle: One minute. PROBABLE CAUSES:1. DEF tank level/temperature sensor harness/connector.2. DEF tank level/temperature sensor.

NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: If the ACM (Computer module) has been programmed recently, clear code, test drive, and if code doesn’t come back releaes the vehicle. PROBABLE CAUSES:1. Check DEF tank header harness connector/wiring.2. DEF CAN harness.3. Failed DEF tank header.
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3056 FMI 2 (ACM) Selective Catalyst Reduction Inlet NOx Sensor – Error
Posted by PerDiezel Solutions on
DESCRIPTION:Selective catalyst reduction (SCR) inlet NOx sensor – Error. MONITORED PARAMETER:SCR inlet NOx. TYPICAL ENABLING CONDITIONS:1. 1000-1800 rpm.2. 35-100% load.3. Steady cruise. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Eight minutes DASH LAMPS:MIL VERIFICATION:1. 1000-1800 rpm.2. 35-100% load.3. Steady cruise.4. Eight minutes. NOTE: If codes 5357-16 or 5357-18 present, fix those first. PROBABLE CAUSES:1. Perform a stationary regen.2. SCR inlet NOx sensor.

Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3058 FMI 10 (MCM) Exhaust Gas Recirculation Valve Actuator Slow Response
Posted by PerDiezel Solutions on
DESCRIPTION:This code sets when the actual EGR flow vs. desired EGR flow is greater than a calibrated threshold during acceleration. MONITORED PARAMETER:1. EGR delta P sensor.2. Intake manifold pressure sensor.3. Intake manifold temperature sensor. TYPICAL ENABLING CONDITIONS:Low engine to high engine load. MONITOR SEQUENCE:1. One second after acceleration load.2. Actual EGR flow vs. desired EGR flow is greater than a calibrated threshold. EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:Five seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:1. Road test with a trailer while performing multiple accelerations.2. Engine load needs to increase above 50% during accelerations and the engine rpm is between 600...
