P269E Exhaust Aftertreatment Glow Plug Control Circuit High

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modeNo

When the exhaust glow plug control circuit reads close to battery voltage at the wrong moment, the control side has contact with a positive feed or the switching stage hangs open, so the vaporizer glow plug may stay energized or ignore commands. On Ford's 3.2 L Transit diesel the 2017 and 2018 summaries set P269E once the circuit holds between 10.9 and 12.32 V for 5 s with the ignition on. The predecessor years filed this under P2689, together with the relay plausibility check that later became P26A0. A glow element that heats without stopping wears out quickly and can draw fuel-free current for long periods, so a later open element code may follow. Regeneration is curtailed and the MIL comes on.

Likely causes

Control wire shorted to a battery-fed circuit
Relay contacts welded, glow plug permanently powered
Output stage in the engine computer defective

Symptoms

  • MIL on
  • Glow plug failing early from constant heating
  • Regeneration curtailed
