Detroit DD13 GHG14 (2014-16) Fault Code: SPN 4795 FMI 31 (ACM) Diesel Particulate Filter Outlet Temperature Response – Too Fast
NOTE: This fault indicates the Aftertreatment Control Module (ACM) has detected a sudden temperature shift on the Diesel Particulate Filter (DPF) outlet temperature sensor. The most likely cause is an intermittent wiring concern (poor terminal fit, corrosion, chaffing, etc.).
NOTE: Please see the step by step troubleshooting procedures for this specific code.
NOTE: If 3246-3 or 3246-4 are active, fix those first.
PROBABLE CAUSES:
1. Check all wiring and connectors for the DPF outlet temperature sensor.
2. DPF outlet temperature sensor.
3. Inspect all harnesses and connectors between the DPF outlet temperature sensor and the ACM (Aftertreament Control Module).
