The P2695: Cylinder 10 Injector Data Incompatible code indicates that the ECM/PCM has detected incompatible or incorrect data for the fuel injector in Cylinder 10. This may occur if the injector was replaced without the appropriate programming, if there is incorrect or corrupted calibration data, or due to ECM/PCM issues. Correct calibration is necessary for proper injector function and optimal engine performance.
P2695 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P2695: Cylinder 10 Injector Data Incompatible |
| Is it serious? | Yes, as incompatible injector data can lead to improper fuel delivery, engine misfires, reduced performance, and increased emissions. |
| Possible causes | – Incompatible or faulty injector data – Injector replacement without proper programming – Faulty ECM/PCM or data issues |
| How to diagnose? | – Check injector data for Cylinder 10 – Verify compatibility and programming – Inspect ECM/PCM for faults – Reprogram or replace components as needed |
P2695 Meaning
The P2695: Cylinder 10 Injector Data Incompatible code means that the ECM/PCM is unable to recognize or use the calibration data for the injector in Cylinder 10. This could be due to a new injector being installed without proper calibration, an incompatible injector being used, or data issues within the ECM/PCM. Proper injector calibration is vital for efficient fuel delivery and engine performance, ensuring optimal combustion and reducing emissions.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to determine if any other related codes are present. Other codes may indicate additional issues with injectors or ECM/PCM. | OBD-II Scanner |
| Check Injector Data for Cylinder 10 | Verify the calibration data for the injector in Cylinder 10 against manufacturer’s specifications. Ensure that the injector type and data match the vehicle’s requirements. | Manufacturer’s Service Information, Diagnostic Tool |
| Verify Compatibility and Programming | Confirm that the injector installed in Cylinder 10 is compatible and has been properly programmed into the ECM/PCM. If the injector was recently replaced, ensure that calibration was completed successfully. | Manufacturer-Specific Calibration Tool |
| Inspect ECM/PCM | Inspect the ECM/PCM for faults such as data retention issues or internal communication errors that could prevent proper injector calibration or data processing. | Diagnostic Scanner, Specialized PCM Testing Tool |
| Check Wiring and Connections | Inspect the wiring and connectors between the ECM/PCM and the Cylinder 10 injector. Look for any signs of damage, loose connections, or corrosion that could interfere with data transmission. | Flashlight, Multimeter |
| Reprogram the ECM/PCM | If the data is incorrect, reprogram the ECM/PCM using the correct calibration data for Cylinder 10. Ensure you use updated software and correct specifications from the manufacturer. | ECM/PCM Programming Tool |
| Replace Faulty Components | Replace any faulty components identified during the inspection, including the injector itself, ECM/PCM, or any damaged wiring and connectors, to ensure proper functionality. | Replacement Parts |
| Clear the Code and Test System | After performing calibration or component replacement, use an OBD-II scanner to clear the error code. Conduct a test drive to verify that the ECM/PCM has properly accepted the data and that the engine is running efficiently. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the vehicle to confirm that the P2695 code has not returned and verify that the injector system for Cylinder 10 is functioning correctly. | OBD-II Scanner |
