P2694Cylinder 9 Injector Data Incompatible
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2694 would flag bad or missing correction data for the injector in cylinder 9 and therefore only fits engines with nine or more cylinders, in road vehicles essentially V10s. No manufacturer documents this code publicly. GM's diesel tables end at P2693 for eight cylinders, and Ford's 2023 diesel summary covers the same eight codes; neither lists a cylinder 9 entry. The logic would follow theirs: a missing, out-of-range or checksum-failing code for that injector sets the fault, as CARB demands for coded injectors from 2015 on. If P2694 shows up on an engine with eight cylinders or fewer, suspect a scan tool decoding error or wrong software rather than an injector.
- What you may notice
- Check engine light on
- Usually no noticeable symptoms
- Likely causes
- PossibleCylinder 9 injector code not programmed (ten-cylinder engines)
- PossibleScan tool decoding error on engines without a ninth cylinder
- RareController software for a different engine
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
