Description:

This error code indicates a failure in the calibration process of the VGT actuator, potentially due to incorrect installation, defective components, or improper configuration settings.

Reaction:

The ECU may limit the functionality of the turbocharger to prevent operation outside of safe or efficient parameters.

Recommendations:

• Verify Actuator Installation and Configuration: Check that the actuator is installed correctly and configured according to manufacturer specifications.
• Re-calibrate the VGT Actuator: Use appropriate diagnostic tools to calibrate the actuator. Ensure all parameters are set correctly.
• Replace Defective Actuator: If calibration fails due to hardware issues, replace the actuator.
• Reset ECU and Perform Functional Tests: After successful calibration or replacement, reset the ECU to clear any lingering error states and perform functional tests to verify correct operation.

Note:

Accurate calibration of the VGT actuator is essential for turbocharger performance and overall engine efficiency. Regular checks and calibration are recommended to maintain system integrity and performance.
