Detroit DD13 EPA10 (2010-13) Fault Code: SPN 3246 FMI 8 (ACM) Diesel Particulate Filter Outlet Temperature – Signal Spike
Posted by Diezel Solutions on
NOTE: This fault indicates the aftertreatment control module (ACM) has detected a sudden temperature shift on the Diesel Particulate filter (DPF) outlet temperature sensor. POSSIBLE CAUSES:1. Wiring.2. Poor terminal fit.3. Corrosion.4. Chaffing . PROBABLE CAUSES:1. DPF outlet temperature sensor.2. DPF outlet temperature sensor connector/harness.

Detroit DD13 EPA10 (2010-13) Fault Code: SPN 3250 FMI 0 (ACM) Diesel Oxidation Catalyst Outlet Temperature Very High
Posted by Diezel Solutions on
DESCRIPTION:This code sets when the diesel oxidation catalyst (DOC) outlet temperature is greater than 760°C (1400°F) for more than two seconds. MONITORED PARAMETER:Diesel oxidation catalyst temperature sensor. 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 regeneration NOTE: If any other codes active, fix those first. PROBABLE CAUSES:1. DOC outlet temperature sensor harness/connector.2. DOC outlet temperature sensor.3. Failed fuel injector.4. Remove the DPF and inspect for coolant or oil contamination. If found, find source of leak.5. Perform a parked regen.6. Electrical connections upstream of the ECM...
Detroit DD13 EPA10 (2010-13) Fault Code: SPN 3250 FMI 14 (ACM) Abnormal Diesel Oxidation Catalyst Temperature Rise 2
Posted by Diezel Solutions on
NOTE: Excessive idle times may lead to this fault due to high HC accumulation on the diesel oxidation catalyst (DOC). 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 or charge air cooler failure.10. Intake manifold pressure sensor.11. Turbocharger failure.12. Fuel doser injector...

NOTE: Please see the step by step troubleshooting procedures for this specific code. 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 DD13 EPA10 (2010-13) Fault Code: SPN 3250 FMI 20 (ACM) Diesel Oxidation Catalyst Temperature Drift – Inlet Low or Outlet High
Posted by Diezel 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.
