Ford Trucks fault codes

Updated: 2026-11-10

The reference covers 407 Ford Trucks codes from factory tables — the code and what it means. Ford Trucks numbers faults its own way, not by J1939 SPN.

Ford Trucks codes: what to know

Ford Trucks and Ecotorq record the number in their own scheme, not as a J1939 SPN: before the dot is the fault number in digits (leading zeros are not on every code), after the dot is the fault type in digits and letters A–F, for example 6.1F. There are 407 codes, all gathered on this page with the factory description for each number. A number that matches an SPN on another page means something else, so look the code up by its full number from the reading, not by an SPN.

All Ford Trucks codes — 407

How to read the number

Ford Trucks numbers its faults its own way, not by the J1939 SPN standard: the first part is the fault number, after the dot — its type. The same number on an engine or another make means something else.

If there are several codes at once

That is almost always how it goes: one fault drags five or six codes behind it. An empty AdBlue tank first throws a level error, then interrupted dosing, then a NOx excess and a torque derate. Fix the root cause and the rest clear on their own. Paste the whole list — we will show which code is the root cause.

Know the code number? Type it into the search — or paste the whole list from the scanner and we will show which fault is the real one.
