I have been fighting a P0406, I did not find any damage on the wire harness, and I have replaced both the ERG Valve and Tube.

Hi,
I have a feeling there is a short to power at some point. When you checked the wire harness, did you test the wires themselves or was it a visual inspection only?
As far as tests, I attached the diagnostics below specific to this code for your vehicle. Take a look through them and let me know if you are comfortable performing them.
Take care and Happy 4th.
