What P2694 means
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.
P2694 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2694
- Check engine light on
- Usually no noticeable symptoms
Common causes of P2694
- PossibleCylinder 9 injector code not programmed (ten-cylinder engines)
- PossibleScan tool decoding error on engines without a ninth cylinder
- Less likelyController software for a different engine
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2694 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 6 | Area: computer (engine control module) and output circuits. |
| 94 | The exact fault in that area. |
What to do next
- Note P2694 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2694
What does P2694 mean?
P2694 means "Cylinder 9 Injector Data Incompatible". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2694?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2694 fail an emissions test?
Yes, it can. P2694 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2694 to fix?
Difficulty: medium. A typical repair takes 0.3 to 1.5 hours of work. This is a job for a workshop.
Will P2694 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
