Detroit DD16 GHG14 (2014-16) Fault Code: SPN 5018 FMI 18 (ACM) Diesel Oxidation Catalyst Efficiency Fault
Posted by PerDiezel Solutions on
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....
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 51 FMI 10 (MCM) Intake Throttle Position Abnormal Rate of Change
Posted by PerDiezel Solutions on
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...
