Cylinder 10 Injector Data Incompatible
The P2695 code indicates that the Engine Control Module (ECM) has detected a mismatch between the expected and actual data from the fuel injector on cylinder 10. This typically occurs when an incorrect injector is installed, the injector's calibration data is not programmed into the ECM, or there is a wiring/communication issue between the injector and the ECM. The ECM uses injector flow rate and trim data to optimize fuel delivery; incompatibility can cause poor engine performance, misfires, and increased emissions.
01. Most Common Causes
- Incorrect fuel injector installed (wrong part number or flow rate)
- Injector calibration data not programmed or updated in ECM
- Faulty injector wiring or connector at cylinder 10
- ECM software issue or corruption
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine misfire or rough idle
- Reduced fuel economy and performance
- Possible hesitation or stumbling under load
03. Step-by-Step Diagnosis
Step 1: Scan the ECM for all codes and freeze frame data to confirm P2695 and related codes.
Step 2: Visually inspect the injector connector and wiring at cylinder 10 for damage, corrosion, or loose pins.
Step 3: Use a scan tool to check injector calibration data; compare the injector part number installed to the one stored in the ECM.
Step 4: If the injector is incorrect, replace it with the correct part and program the injector calibration data using a factory-level scan tool.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the engine may run poorly, cause misfires, and potentially damage the catalytic converter or other components.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and programming, plus the cost of a new injector if needed (which can add $100-$300 per injector).
