P2692 Cylinder 7 Injector Data Incompatible

Only engines with seven or more cylinders can log P2692, which in practice means V8 diesels. It tells that the correction code for the cylinder 7 injector has not been stored or is unusable. GM carries it in every eight-cylinder diesel table from 17OBDG04 (2017) to 25OBDG04A (2025); the 2017 and 2020 versions evaluate it at ignition on, Type A in one trip, with the value expected under DID $66. Ford lists it in its 2023 diesel summary, where only the 6.7 L V8 has a seventh cylinder. Typical triggers are injector replacement on that cylinder or a swapped controller. Six-cylinder and smaller engines setting P2692 would point to a wrong software variant.

Likely causes

Injector in cylinder 7 replaced, code not programmed
Replacement controller without the vehicle's injector codes
Software variant for the wrong engine configuration

Symptoms

  • Check engine light on
  • Usually no drivability change
