P269F: Exhaust Aftertreatment Glow Plug Circuit/Open

While P269B concerns the line that commands the exhaust glow plug, P269F targets the load circuit itself: the heating element or its power feed is open, so no current flows even when the control stage switches correctly. A burnt-out element is the usual reason, followed by a loose terminal at the plug in the hot exhaust area. There is no public manufacturer documentation for P269F. Ford's Transit with the 3.2 L engine, the documented user of this glow plug family, reports its vaporizer glow plug faults through the control codes P269B, P269D, P269E and P26A0 instead. CARB requires output components of an emission-related system to be checked for circuit faults. Without heat the injected fuel cannot vaporize, so the engine limits exhaust dosing and regeneration.

Low severity. Can I keep driving?You can keep driving, although cold starts will be harder. Avoid cranking the starter repeatedly on cold days.

Symptoms

MIL on
Particulate filter regenerations fail

Most likely causes

Glow element burnt out
Loose or corroded terminal nut at the plug
Blown fuse in the glow plug power circuit

What to check, in order

Start with the simplest. You can tick off each step.

Check the fuse and connector
Check the continuity of the wire between the component and the control module.
Measure the resistance of each glow plug with the engine cold
Check the power supply during the preheat cycle
Test the module or relay if the glow plugs are good

Good to know

Repair difficulty: medium
It affects emissions.
