P2695: Cylinder 10 Injector Data Incompatible

What it means

The flow calibration data programmed for cylinder 10 injector does not match the format expected by the controller software.

At a glance

• Usually lights the check-engine light

How it works

The controller uses separate flow calibration data for each injector to meter fuel accurately. P2695 sets when the calibration assigned to the cylinder 10 injector is incompatible with the controller's expected data format or software version.

Common causes

Most likely first.

1. Replacement injector has different part number than software expects
2. Calibration code format does not match controller version

Symptoms

• Check-engine light
• Possible rough running or reduced power

How to diagnose it

1. Check freeze-frame data and repair history for recent work on the cylinder 10 injector or controller.
2. Confirm the cylinder 10 injector part number and calibration identifier are specified for this vehicle and controller.
3. Inspect the cylinder 10 injector connector and wiring for a loose connection, damaged terminal, or disturbed harness.
4. Use a capable scan tool to retrieve the cylinder 10 calibration and compare its format with the controller's requirements.
5. If the correct injector and data are present, verify software compatibility before attempting reprogramming.

Common fixes

• Program the correct cylinder 10 injector calibration data.
• Replace a cylinder 10 injector that does not match the vehicle's specification.
• Apply a supported controller update or configuration if its software cannot accept the correct calibration format.

Can I keep driving?

If the engine runs smoothly, keep any driving gentle and brief until repaired; avoid towing or hard acceleration if power is reduced. Continued incorrect fueling on cylinder 10 can cause rough operation and further engine stress.
