Diagnostic Overview

MaxxForce fault code SPN 912 is listed in the EGR category in the supplied file, but the FMI is not provided. Treat it as an EGR-related fault family until the full diagnostic description is confirmed. It may relate to EGR position, EGR flow calculation, or an air-management input used by the ECM. The exact repair path depends on the missing FMI and engine calibration.

Likely Causes

EGR valve issue, EGR sensor problem, wiring fault, poor connector contact, air-management sensor issue, carbon buildup, or related turbo/boost problem.

What To Check First

Retrieve the full SPN/FMI and manufacturer description, review live EGR data, inspect connectors and wiring, and check for related EGR valve, EGR flow, or boost codes.
