P2693 Cylinder 8 Injector Data Incompatible

EmissionsRelevant
Drive cycleNot required
Limp modeNo

P2693 completes the series on V8 engines and covers the injector in cylinder 8. It is set when the controller finds no valid flow correction code for that position. In GM's 2018 table 18OBDG04 the code reads DID $67 and fails only once the manufacturer enable counter is zero; the 2025 table 25OBDG04A instead keeps the check permanently on in production units. Both rate it Type A. Ford's 2023 diesel summary covers it for the 6.7 L Power Stroke with a continuous check of about 0.5 s. When all eight codes appear together, a new or reset controller is far more likely than eight bad injectors; a lone P2693 points to work on that one injector.

Likely causes

Code of the new cylinder 8 injector not entered
New or reset controller lacking all injector codes
Typing error in the cylinder 8 code

Symptoms

  • Check engine light on
  • Possible rough idle or knock
