P269BExhaust Aftertreatment Glow Plug Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- Some diesels inject fuel into the exhaust through a small vaporizer whose glow plug turns the fuel into vapor before it reaches the oxidation catalyst. Ford calls this downstream injection (DSI) on the 3.2 L Transit, used so that filter regeneration needs fewer in-cylinder post injections and less oil is diluted. P269B covers an open in the circuit by which the engine computer controls that glow plug. Ford's diesel summaries from 2017 and 2018 watch the line continuously with key on at 9 to 16.3 V battery voltage and set the open fault when the voltage stays between 2.9 and 3.2 V for 5 s. The 2015 and 2016 summaries reported the same condition as P2687. With the plug dead the fuel cannot be vaporized, so regeneration is cut back and the lamp comes on.
- What you may notice
- MIL on
- Particulate filter regenerations fail or become rare
- More frequent in-cylinder regeneration, oil level may rise
- Likely causes
- LikelyOpen wire or connector between engine computer and glow plug relay
- PossibleVaporizer glow plug relay coil open
- RareBlown fuse in the glow plug control feed
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
