Detroit DD13 EPA10 (2010-13) Fault Code: SPN 3250 FMI 8 (ACM) Diesel Oxidation Catalyst Outlet Temperature – Signal Spike
Posted by Diezel Solutions on
DESCRIPTION:This fault indicates the aftertreatment control module (ACM) has detected a sudden temperature shift on the diesel oxidation catalyst (DOC) outlet temperature sensor. MONITORED PARAMETER:DOC outlet temperature. TYPICAL ENABLING CONDITIONS:DOC outlet temperature greater than 150°C (302°F). MONITOR SEQUENCE:None EXECUTION FREQUENCY:None TYPICAL DURATION:10 seconds DASH LAMPS:1. CEL2. MIL ENGINE REACTION:None VERIFICATION:Low temp ATD check. POSSIBLE CAUSES:1. Wiring concern.2. Poor terminal fit.3. Corrosion.4. Chaffing. NOTE: If codes 3250-3 or 3250-4 active, fix those first. PROBABLE CAUSES:1. DOC outlet temperature sensor.2. DOC outlet temperature sensor harness/connector. Detroit DD13 EPA10 (2010-13) Fault Code: SPN 3250 FMI 4 (ACM) Diesel Oxidation Catalyst Outlet Temperature Circuit...
Detroit DD13 EPA10 (2010-13) Fault Code: SPN 3251 FMI 0 (ACM) Diesel Particulate Filter Pressure Out of Range Very High
Posted by Diezel Solutions on
DESCRIPTION:This fault code sets when the diesel oxidation catalyst (DOC) inlet pressure is 35 kPa (5 psi) greater than diesel particulate filter (DPF) outlet pressure for more than 10 seconds. MONITORED PARAMETER:DOC inlet pressure sensor and 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 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...
