ECU 000641.13 – Turbocharger Actuator Learned Value Error (VGT Actuator Calibration Error). John Deere System Advisory.

ECU 000641.13 (ECU 641.13)

Code: 000641.13

Shortcode: 641.13

Description:

This diagnostic trouble code, ECU 000641.13, is set when the turbocharger actuator determines that its learned value is incorrect, indicating a calibration failure of the VGT actuator. This error can lead to improper turbocharger regulation.

Reaction:

The ECU may limit turbocharger operation to prevent damage due to incorrect calibration values.

Recommendations:

  • Recalibrate VGT Actuator: Perform the actuator learning procedure again using the appropriate diagnostic tools and following the manufacturer’s guidelines.
  • Inspect Actuator and Connections: Ensure that the VGT actuator and its connections are free from mechanical obstructions and that the wiring is intact.
  • Test Actuator Functionality: Verify that the actuator moves smoothly and responds correctly during the calibration process.
  • Replace Faulty Actuator if Needed: If the actuator continues to fail calibration, consider replacing it with a new one.
  • Reset ECU and Verify Calibration: After successful calibration, reset the ECU and test the system to confirm that the learned values are correct and the actuator operates properly.

Note:

Accurate calibration of the VGT actuator is crucial for maintaining efficient turbocharger operation and overall engine performance.
