3361

Exhaust gas recirculation valve, cooler, and flow faults.

System
MaxxForce EGR

Diagnostic Overview

MaxxForce fault code 3361 appears in the EGR section of the supplied list, but 3361 can also appear in DEF/aftertreatment contexts on some systems. Because the code is not written with SPN/FMI detail, it should be verified before assigning it to a single component. If it appears with EGR symptoms, the technician should check whether it is a standalone manufacturer code or whether another EGR code is active at the same time.

Likely Causes

Possible EGR control issue, sensor or wiring fault, or miscategorized DEF/aftertreatment code depending on diagnostic software output and engine calibration.

What To Check First

Confirm the code source and full description in ServiceMaxx, check whether it is listed as engine or aftertreatment, review companion codes, and inspect the related system before making repairs.
