Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3246 FMI 3 (ACM) Diesel Particulate Filter Outlet Temperature Sensor Circuit Failed High
Posted by PerDiezel Solutions on
NOTE: Please see the step by step troubleshooting procedures for this specific code. 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.

Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3246 FMI 7 (ACM) DPF Outlet Temperature Sensor Not Responding
Posted by PerDiezel Solutions on
DESCRIPTION:Diesel particulate filter (dpf) outlet. MONITORED PARAMETER:DPF outlet temperature sensor. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions are met. TYPICAL DURATION:Five seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:Parked regeneration 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.
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3246 FMI 8 (ACM) Diesel Particulate Filter Outlet Temperature – Signal Spike
Posted by PerDiezel 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. NOTE: If codes 3246-3 or 3246-4 active, fix those first. PROBABLE CAUSES:1. DPF outlet temperature sensor.2. DPF outlet temperature sensor connector/harness.
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3250 FMI 0 (ACM) Diesel Oxidation Catalyst Outlet Temperature Very High
Posted by PerDiezel 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...
