P2692: Cylinder 7 Injector Data Incompatible

What it means

The flow calibration data programmed for cylinder 7 injector does not match the format expected by the controller software.

At a glance

• Usually lights the check-engine light

How it works

The engine controller relies on injector flow data to meter fuel for each cylinder. P2692 sets when the calibration data assigned to the cylinder 7 injector is incompatible with the format or version the controller expects.

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 scan-tool records for recent injector replacement or calibration work involving cylinder 7.
2. Confirm the cylinder 7 injector part number and calibration identifier match the vehicle's specified injector and controller software.
3. Inspect the cylinder 7 injector connector and harness for loose or damaged terminals, especially if the area was disturbed during a repair.
4. Read the cylinder 7 calibration data with a capable scan tool and compare its format with the controller's requirements.
5. If the injector and entered data are correct, check whether the controller software needs a supported update or configuration.

Common fixes

• Correct the cylinder 7 injector calibration entry with compatible data.
• Fit the specified cylinder 7 injector if the installed unit is incompatible.
• Update or configure the controller software when required to accept the correct calibration format.

Can I keep driving?

A gentle, short drive may be reasonable if the engine runs normally, but avoid towing or hard acceleration if it runs rough or loses power. Persistent fueling errors on cylinder 7 can affect engine operation and may cause further damage.
