P269DExhaust Aftertreatment Glow Plug Control Circuit Low

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
How the car detects it
A low reading on the exhaust glow plug control line points to a path to ground before the load, so the control stage cannot set the right level and the vaporizer glow plug may be switched wrongly. Ford is the documented user: in its 2017 and 2018 diesel summaries the 3.2 L Transit judges the downstream injection glow plug circuit by voltage windows, and a reading held between 1.95 and 2.175 V for 5 s is classed as a short to ground (key on, battery 9–16.3 V). In 2015 and 2016 Ford used P2688 for the identical window. Typical findings are a pinched wire near the exhaust or a shorted relay coil. The DPF regeneration that relies on vaporized fuel is held back until the circuit is repaired.
What you may notice
  • MIL on
  • Regeneration suspended, rising soot load
  • Possible blown fuse in the glow plug feed
Likely causes
  • LikelyControl wire chafed on the exhaust or body and grounded
  • PossibleShorted coil in the glow plug relay
  • RareHeat-damaged connector near the vaporizer
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
