P269F Exhaust Aftertreatment Glow Plug Circuit/Open

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modeNo

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.

Likely causes

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

Symptoms

  • MIL on
  • Particulate filter regenerations fail
