Detroit DD13 EPA10 (2010-13) Fault Code: SPN 4363 FMI 3 (ACM) Selective Catalyst Reduction Outlet Temperature Sensor Circuit Failed High
Posted by Diezel Solutions on
DESCRIPTION:This fault code sets when there is an open in the SCR outlet temperature circuit or a short to power on the SCR outlet temperature sensor signal circuit. MONITORED PARAMETER:SCR inlet temperature sensor. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:2 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25%. VERIFICATION:Engine idle (one minute). NOTE: If code 3246-15 active, fix that first. PROBABLE CAUSES:1. Inspect all connectors and wiring upstream of the ACM (SCR inlet temp, ATD harness 10-pin connector, VIH 47-pin connector, and ECM 120-pin connector).2. SCR outlet temperature sensor.3. SCR outlet temperature sensor connector/harness. Detroit DD13...

Detroit DD13 EPA10 (2010-13) Fault Code: SPN 4363 FMI 8 (ACM) SCR Outlet Temperature Signal Spike
Posted by Diezel Solutions on
DESCRIPTION:This fault code sets when the Aftertreatment Control Module (ACM) detects a momentary abnormal Selective Catalyst Reduction (SCR) outlet temperature reading. MONITORED PARAMETER:Selective Catalyst Reduction outlet temperature sensor. TYPICAL ENABLING CONDITIONS:Non-Regen mode. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:2 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:SCR efficiency test. NOTE: This fault indicates that the ACM has detected a sudden temperature switch on the SCR inlet temperature sensor. Most likely cause is wiring failure. NOTE: If codes 4363-3 or 4363-4 are active, fix those first. PROBABLE CAUSES:1. Check all SCR sensor wiring for looseness, breaks, rubs, etc…2....
Detroit DD13 EPA10 (2010-13) Fault Code: SPN 4364 FMI 1 (ACM) Selective Catalyst Reduction NOx Conversion Very Low
Posted by Diezel Solutions on
DESCRIPTION:Selective Catalyst Reduction NOx conversion very low. MONITORED PARAMETER:1. Selective Catalyst Reduction (SCR) inlet NOx sensor.2. SCR outlet NOx sensor. TYPICAL ENABLING CONDITIONS:1. Diesel Exhaust Fluid (DEF) dosing enabled.2. 1000 – 1500 rpm.3. 15 – 100% load.4. SCR inlet temperature sensor less than 650°C (1200°F).5. Ambient temperature greater than 0°C (32°F).6. Coolant temperature greater than 70°C (158°F).7. Non-regeneration conditions present. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:30 minutes DASH LAMPS:MIL ENGINE REACTION:Derate 25% VERIFICATION:Parked regeneration NOTE: If any 3364-xx codes present, fix those first. PROBABLE CAUSES:1. DEF tank contaminated (fuel, water, etc…).2. DEF pressure sensor failure.3. DEF...
