Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3250 FMI 15 (ACM) Diesel Oxidation Catalyst Outlet Temperature High
Posted by PerDiezel Solutions on
DESCRIPTION:Exhaust temperature high. 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:MIL ENGINE REACTION:None VERIFICATION:Parked regeneration NOTE: If any other codes active, fix those first. PROBABLE CAUSES:1. Inspect the DOC outlet temperature sensor connector/harness.2. Check connections upstream of the ECM (ATD harness 10-pin connector, VIH 31-pin connector, and MCM 120-pin connector).3. DOC outlet temperature sensor.4. Failed cylinder injector.5. Inspect the DPF face for oil or coolant contamination – if present, find source.6. Perform a parked regen.
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3250 FMI 20 (ACM) Diesel Oxidation Catalyst Temperature Drift – Inlet Low or Outlet High
Posted by PerDiezel Solutions on
DESCRIPTION:70°C (126°F) difference during non-regeneration mode. MONITORED PARAMETER:Diesel Oxidation Catalyst (DOC) Inlet Temperature vs. DOC Outlet Temperature. TYPICAL ENABLING CONDITIONS:Coolant temperature greater than 60°C (140°F), regen not active in last five minutes. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:One minute DASH LAMPS:1. CEL2. MIL ENGINE REACTION:Regen Inhibit and 10% Engine Derate. VERIFICATION:Low Temperature Regen. PROBABLE CAUSES:1. DOC outlet temperature sensor harness/connector.2. DOC outlet temperature sensor.

NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: If codes 3250-3, 3242-3, 3246-3, or 1172-3 are active, fix those first. PROBABLE CAUSES:1. Turbocharger compressor inlet sensor.2. Turbocharger compressor inlet sensor harness/connector.3. DOC outlet temperature sensor.4. DOC outlet temperature sensor harness/connector.
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3250 FMI 31 (ACM) Abnormal Diesel Oxidation Catalyst Temperature Rise
Posted by PerDiezel Solutions on
DESCRIPTION:Abnormal diesel oxidation catalyst (DOC) temperature rise. MONITORED PARAMETER:DOC 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:25% Derate VERIFICATION:Parked regen NOTE: If any other codes are active, fix those first. PROBABLE CAUSES:1. Inspect all connectors upstream of the MCM (DOC outlet temperature, ATD harness 10-pin connector, VIH 31-pin connector, and ECM 120-pin connector).2. DOC outlet temperature sensor.3. DPF inlet pressure sensor.4. DPF inlet pressure sensor connector/harness.5. DPF outlet pressure sensor.6. DPF outlet pressure sensor connector/harness.7. DPF is contaminated with oil or coolant.8. DOC failure.9. Intake manifold...
