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 DD13 EPA07 (2007-09) Fault Code: SPN 3250 FMI 16 (MCM) Diesel Oxidation Catalyst Outlet Temperature High Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3250 FMI 14 (MCM) Abnormal Diesel Oxidation Catalyst Temperature Rise Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3250 FMI 10 (MCM) Diesel Oxidation Catalyst Outlet Temperature Sensor Stuck Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3250 FMI 8 (MCM) Diesel Oxidation Catalyst Outlet...

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 valve leaks.13. Failed cylinder injectors.14. DPF failure.15. Perform a stationary regen. Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3250 FMI...

NOTE: This fault indicates the Motor Control Module (MCM) has detected an impossible temperature shift on the Diesel Oxidation Catalyst (DOC) outlet temperature sensor. The most likely cause is an intermittent wiring concern. 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...

NOTE:This fault code sets when the Diesel Particulate Filter (DPF) outlet pressure is greater than 35 kPa (5 psi) for more than 10 seconds. DESCRIPTION:DPF pressure out of range very high. MONITORED PARAMETER:Exhaust Pressure TYPICAL ENABLING CONDITIONS:Always on MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL3. SEL ENGINE REACTION:Derate 25% VERIFICATION:Run engine between 1200 to 1800 rpm with a load less than 10%. PROBABLE CAUSES:1. Inspect all connections upstream of the MCM – DPF inlet pressure sensor, ATD harness 10-pin connector, VIH 31-pin connector, and MCM 120-pin connector.2. DPF inlet pressure sensor.3. DPF...

DESCRIPTION:DPF pressure out of range low. MONITORED PARAMETER:1. DPF inlet pressure sensor.2. DPF outlet pressure sensor. TYPICAL ENABLING CONDITIONS:Always on MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL3. SEL ENGINE REACTION:Derate 25% VERIFICATION:Run engine between 1500 to 1900 rpm with a load less than 80%. PROBABLE CAUSES:1. Inspect DPF outlet pressure hose for leaks/kinks/plugging.2. Inspect electrical connections upstream of the MCM (sensor, ATD 10-pin connector, VIH 31-pin connector, MCM 120-pin connector).3. Remove the DPF and inspect for signs of oil, fuel, or soot contamination. If found, find source.4. DPF failure.5. Performed parked regen....
