P2695: Cylinder 10 Injector Data Incompatible

P2695 is reserved for the injector in cylinder 10, the highest cylinder number the J2012 series provides with its own data code. A ten-cylinder engine with individually coded injectors would be needed to set it, and none of the public OBD summaries reviewed here contains it: GM's 2025 V8 diesel table 25OBDG04A and Ford's 2023 diesel summary both stop at cylinder 8. CARB's rule that the stored code should, where feasible, identify the wrongly compensated injector explains why the series reaches this far. Engines with more than ten cylinders have to fall back on P2696. On ordinary cars and trucks P2695 is very unlikely to appear and should first be verified with a second tool.

Cylinder 10 is numbered according to the manufacturer: check your engine's manual before working on it.

Symptoms

• Check engine light on
• Usually no noticeable symptoms

Most likely causes

• Cylinder 10 injector code missing on a ten-cylinder engine
• Misread code on engines with fewer cylinders
• Controller memory or software fault

What to check, in order

Start with the simplest. You can tick off each step.

1. Check the connector and wiring of the injector indicated
2. Measure the resistance and compare it with the manufacturer's specification
3. Check the control signal with an oscilloscope; on direct injection or diesel engines, leave this to a repair shop because of the high voltages
4. On diesels, check the per-cylinder injection corrections

Good to know

• Repair difficulty: medium
• It affects emissions.

What each character of P2695 means

• P: Powertrain: engine and transmission
• 2: Generic code: same on every make
• 6: Control modules and outputs
• 95: Specific fault in that system

Frequently asked questions

Can I keep driving with code P2695?

Drive as little as possible and go to a repair shop. If you smell fuel or the engine is shaking badly, do not keep driving.

What causes code P2695?

The most common causes are: cylinder 10 injector code missing on a ten-cylinder engine; misread code on engines with fewer cylinders; controller memory or software fault.
