NOTE: If 3246-0 active, fix that first. NOTE: If 3246-8 active, fix that first. NOTE: If 3246-16 has more than 5 counts, use 3246-0. PROBABLE CAUSES:Perform a parked regen. Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3246 FMI 0 (MCM) Diesel Particulate Filter Outlet Temperature Very High Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3242 FMI 10 (MCM) Failed Diesel Oxidation Catalyst Inlet Temperature Sensor Detroit DD13 EPA07 (2007-09) Fault Code: SPN 3242 FMI 8 (MCM) Motor Control Module Has Detected an Impossible Temperature Shift on the Diesel Oxidation Catalyst Inlet Temperature Sensor Detroit DD13 EPA07 (2007-09) Fault Code: SPN...

NOTE: If codes 3246-3, 3242-3, 3250-3 or 1172-3 active, fix those first. PROBABLE CAUSES:1. Wiring between the turbocharger compressor inlet temperature and the 120-pin MCM connection.2. DPF outlet temperature sensor.3. DPF outlet temperature sensor connector/harness.

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 can also cause this code: ATD harness 10-pin connector, VIH 31-pin connector, and MCM 120-pin connector.7. DPF inlet pressure sensor.8. DPF inlet pressure sensor harness/connector.
