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 injector is replaced without proper calibration or when the injector's internal coding does not match the vehicle's specifications. The ECM uses injector-specific data to optimize fuel delivery, and incompatibility can lead to poor engine performance, misfires, and increased emissions.
1. Most Common Causes
- Incorrect injector part number installed
- Injector not programmed or coded to the ECM
- Faulty injector with corrupted internal data
- ECM software issue requiring update
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine misfire or rough idle
- Reduced fuel economy
- Loss of power under acceleration
3. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all codes and freeze frame data.
Step 2: Verify injector part number on cylinder 10 matches OEM specifications.
Step 3: Perform injector coding procedure using a compatible scan tool.
Step 4: If coding fails, replace injector and repeat coding.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause engine misfire, reduced performance, and potential damage to the catalytic converter.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and injector coding, but if injector replacement is needed, it can be $200-$500 per injector plus labor.
