Detroit DD13 EPA10 (2010-13) Fault Code: SPN 3226 FMI 2 (ACM) Selective Catalyst Reduction Outlet NOx Sensor – Drift
Geplaatst door Diezel Solutions op
DESCRIPTION:Outlet NOx sensor is drifted. MONITORED PARAMETER:1. Selective catalyst reduction (SCR) outlet NOx.2. Engine speed between 1000 to 2000 rpm.3. Engine load between 25 to 100%. TYPICAL ENABLING CONDITIONS:1. SCR temperature greater than 390°C (734°F) for 10 seconds.2. Inlet NOx to outlet NOx deviation greater than 200 ppm. MONITOR SEQUENCE:Once per drive cycle. EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:20 seconds DASH LAMPS:None ENGINE REACTION:Dosing is disabled. VERIFICATION:Parked regeneration NOTE: If any other EGR codes are active, fix those first. PROBABLE CAUSES:1. Check the aftertreatment system for leaks/damage.2. Perform a high idle regeneration with the metering valve or dosing...
