DESCRIPTION:High side digital output circuit shorted low. MONITORED PARAMETER:High side digital output. TYPICAL ENABLING CONDITIONS:Always on MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:Key cycle NOTE: The supply voltage circuit is networked internal of the Aftertreatment Control Module (ACM). This circuit supplies voltage to the Coolant Valve, DEF Post Run indicator (if equipped), and the Inlet NOx sensor. A short on any one of those circuits will set this fault code. PROBABLE CAUSES:1. Coolant valve connector/harness.2. Failed ACM (Aftertreament Control Module). Detroit DD16 GHG14 (2014-16) Fault Code: SPN 5016 FMI...

DESCRIPTION:Diesel Oxidation Catalyst (DOC) efficiency fault. MONITORED PARAMETER:Exhaust temperature TYPICAL ENABLING CONDITIONS:Always on MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:Parked regen NOTE: If any other codes are active, repair those first. PROBABLE CAUSES:1. Inspect all wiring & connections upstream of the ACM: DOC outlet temperature, ATD harness 10-pin connector, VIH 47-pin connector, and ACM 120-pin connector.2. DOC outlet temperature sensor failure.3. DOC inlet temperature sensor failure.4. DPF outlet pressure sensor.5. DPF inlet pressure sensor.6. Wiring/connectors for sensors mentioned above.7. Check for the DPF being plugged/failed.8. Perform stationary regen....

NOTE: This code sets when the intake throttle valve (ITV) position is not within 30% of the commanded position during freezing conditions. DESCRIPTION:Intake throttle position abnormal rate of change. MONITORED PARAMETER:Intake Throttle Valve. TYPICAL ENABLING CONDITIONS:Engine rpm = idle or higher. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Five seconds DASH LAMPS:None ENGINE REACTION:No derate VERIFICATION:Engine rpm = idle or higher. POSSIBLE CAUSES:1. Faulty ITV motor.2. Faulty ITV position.3. Frozen (ice buildup) ITV butterfly. PROBABLE CAUSES:1. Air throttle valve harness.2. ITV harness connector.3. Intake throttle valve failure.4. Cold temperatures may falsly cause this code to appear.5. Intake throttle...

DESCRIPTION:This fault sets when intake throttle position does not match requested range. MONITORED PARAMETER:Intake throttle valve (ITV). TYPICAL ENABLING CONDITIONS:Engine rpm = idle or higher.

DESCRIPTION:This fault code sets when there is a short to voltage on the intake throttle valve circuit. MONITORED PARAMETER:Intake air throttle TYPICAL ENABLING CONDITIONS:Key on MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:2 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 10% VERIFICATION:Engine Idle: One minute. PROBABLE CAUSES:1. Air throttle valve harness.2. ITV harness connector.3. Intake throttle valve failure.4. Cold temperatures may falsly cause this code to appear.5. Intake throttle valve sensor.
