What P2693 means
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.
P2693 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 P2693
- Check engine light on
- Possible rough idle or knock
Common causes of P2693
- Most likelyCode of the new cylinder 8 injector not entered
- PossibleNew or reset controller lacking all injector codes
- Less likelyTyping error in the cylinder 8 code
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2693 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. |
| 93 | The exact fault in that area. |
What to do next
- Note P2693 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 P2693
What does P2693 mean?
P2693 means "Cylinder 8 Injector Data Incompatible". P2693 completes the series on V8 engines and covers the injector in cylinder 8. It is a generic code, so it means the same on every make.
Is it safe to drive with P2693?
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 P2693 fail an emissions test?
Yes, it can. P2693 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 P2693 to fix?
Difficulty: medium. A typical repair takes 0.3 to 1.5 hours of work. This is a job for a workshop.
Will P2693 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
