The file is indexed under Cummins ISB6.7 CM2250 DTCs and the extract also lists related CM2250 engine applications for shared aftertreatment procedures: ISX11.9 CM2250, ISC8.3 and ISL9 CM2250, ISX15 CM2250, GX CM2250, QSL9 CM2250, and QSB6.7 CM2250. The fault concerns the aftertreatment diesel particulate filter intake temperature sensor located at the outlet of the diesel oxidation catalyst and before the diesel particulate filter, with OEM service manual guidance required for exact vehicle location. See the manufacturer at Cummins official website.
Who needs this fault code 3311 DTCs manual
This manual is useful for diesel technicians, fleet workshops, and repair shops diagnosing a red STOP ENGINE lamp with SPN 3242 FMI 0. It supports checks with INSITE™ electronic service tool, aftertreatment exhaust gas temperature sensor comparison, injector misfire inspection, turbocharger outlet contamination inspection, aftertreatment fuel injector leak testing, diesel oxidation catalyst inspection, ECM calibration review, and final fault clearing.
The PDF describes a fault that sets when the aftertreatment diesel particulate filter intake temperature is above the maximum engine protection temperature limit. It notes that active and stationary regeneration are disabled, the EGR valve is closed, and engine shutdown is possible if protection shutdown is enabled. Possible causes include a malfunctioning fuel injector allowing unburned fuel into the exhaust, an in-range failed temperature sensor, and excessive engine oil entering the exhaust system.
