P269CExhaust Aftertreatment Glow Plug Control Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P269C is the plausibility counterpart to the electrical control codes: the wires test fine, yet the control stage of the exhaust glow plug does not behave as commanded, for example a relay or driver that does not report the expected state or reacts too slowly. No manufacturer documents this code publicly. The closest documented case is Ford's 3.2 L Transit, where a vaporizer glow plug relay whose feedback disagrees with the command for about 60 s is a recorded fault, filed under P26A0 from 2017 and under P2689 before. CARB requires functional checks of such output components wherever feasible, beyond pure circuit continuity. An affected engine would lose or limit exhaust fuel vaporization, so regeneration suffers and the MIL can be expected.
- What you may notice
- MIL on
- Particulate filter regeneration incomplete
- Likely causes
- LikelyGlow plug relay switching late or not at all
- PossibleFaulty feedback signal from the relay or driver
- RareLow system voltage during the control check
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
