P26A0Exhaust Aftertreatment Glow Plug Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P26A0 says the exhaust glow plug system does not perform as intended, even if no electrical fault is present. Ford gives the clearest picture for the 3.2 L Transit diesel: from the 2017 summary on, the code is set when the feedback of the vaporizer glow plug relay disagrees with its command for roughly 60 s while the key is on, a fault filed under P2689 in earlier years. Ford bulletin 18-2094, superseded by 19-2016, covers 2016–2018 Transits built up to 13 February 2018 that light the MIL with P26A0 and/or P24A0. When these are the only codes, the fix is a new fuel vaporizer glow plug plus a powertrain module update, and the newer bulletin adds checking a 3 A and a 20 A mini fuse. A failing plug starves the regeneration of heat, which is why P24A0 often appears alongside.
