Power loss at mid and high rpm

This is confusing... So the mechanic calls it a EGR tube. The front desk lady said it's a wastegate solenoid and the manager called it an emissions tube and claims Ford calls it a EGR tube.

Bill: Performed EEC found code P0234, Performed PPT HN1-Y, HN2-Y visual concern, vacuum supply - vacuum hose swelled out
Correction/action taken
Removed and replaced hose, cleared code and retested to verify correction
Part: AA5Z9E499A

Referenced as a vacuum tube, I suppose it works as a pseudo EGR tube   $4 part causing all these headaches?  SMH.

SO essentially its only a wategate hose!
The hose swelled out due to Ford NOT installing a hose clamp from the factory!!!  Z

Must have been it, cuz it runs great again.

They fixed it right, then, and that's what matters.  Enjoy!

2013 Fusion SE 2.0L Code P0234 Overboost condition. 

The solution for my vehicle was a wastegate solenoid assembly (CJ5Z-9K378-B) which includes replacement hoses and the clamps.

NOTE DO NOT BUY just the Solenoid Ford part (CJ5Z-9K378-A) which is $20 cheaper.  While they look almost exactly the same, the electric connector is different and it will not fit.  How do I know this?  I am insanely cheap.  This time my frugal nature cost me an additional trip to the parts store for an exchange.
Learn from my error.  You're welcome!

45 min hour install.  20 of that was just finding the location of the part as I did not have a manual. 

Let the car cool completely.
Ramp or jack the vehicle.
Remove the debris shield.
From underneath the vehicle look for the part on the back of the engine, passenger side, near the turbocharger.
Remove the electrical connector, three hoses/clamps.
The part is mounted on a small bracket with a detent to keep it in place.  Wiggle it back and forth to get it off the bracket.
Reverse the process to install the replacement. 

I have seen people quote $300 for diag and installation of this part.  This was not at all a difficult job at all.  Good place to start.

I guess its a personal preference but in the OP case there was no need to replace the whole assembly and instead you only need to replace the 1/4 wastegate hose which is a simple plug & play install located on TOP of the manifold.  Z
