gtyates Posted November 4, 2017 Report Share Posted November 4, 2017 I just purchased a replacement throttle body for my 2013 Edge. I have received it, but I noticed something that i am wondering if this is normal or not. Basically, the butterfly valve is not fully closed on the unit as it sits in the shipping box. Is this normal for this throttle body and does it shut itself completely once in the truck and hooked up? I have replaced throttle bodies before on my Sport Trac, but it is mechanical and not electrical like these are. The Sport Trac one arrived shut. I decided to get proactive and replace mine before failure, We have been experiencing surging idle for a few weeks now and it is getting more noticeable. Since my wife drives the Edge, I do not want a problem to occur with her behind the wheel. Quote Link to comment Share on other sites More sharing options...
akirby Posted November 4, 2017 Report Share Posted November 4, 2017 If it was closed all the way the vehicle wouldn’t idle. Think about it. 1 Quote Link to comment Share on other sites More sharing options...
TurboToad Posted November 4, 2017 Report Share Posted November 4, 2017 I haven't really researched Fords TB but I assumed most every TB had an idle bypass circuit or IAC to allow for different accessory loads at idle, carbon buildup, or to compensate for failing sensors? Even fully closed shouldn't a TB still route minimal air through a separate bypass route within the TB? Quote Link to comment Share on other sites More sharing options...
akirby Posted November 5, 2017 Report Share Posted November 5, 2017 Not sure but I know the Ford TB doesn’t close all the way. Quote Link to comment Share on other sites More sharing options...
omar302 Posted November 5, 2017 Report Share Posted November 5, 2017 Since the Throttle Body is electronic, no need for a separate idle bypass circuit or IAC. As Akirby stated, it is normal that the Throttle Body does not close 100%, it should be very slightly open. Just remove the air intake tube in your Edge & look at the stock throttle body to make sure it is the same. 1 Quote Link to comment Share on other sites More sharing options...
gtyates Posted November 5, 2017 Author Report Share Posted November 5, 2017 Thanks for the responses. I have noticed that this throttle does body does not have a bypass valve. The older style mechanical one that my Sport Trac does have a bypass valve, so the valve does shut completely. Since I have never worked with an electronic one before I was unsure of whether this was correct. I plan to replace this tomorrow, so I will look closely at the existing one and see how it compares.

gtyates Posted November 5, 2017 Author Report Share Posted November 5, 2017 Now I can answer my own initial question and maybe help someone else. When I took the intake tube off of the old throttle body I noticed that the butterfly valve in it was completely closed. Then I pulled the negative battery cable, removed power plug from the throttle body and began removing it. When I got it removed I noticed that it was just like my new one, with the butterfly valve partially open. Maybe this is a default position when there is no power to the unit? I do not know, but I can only relay the experience I had today, In regards to new throttle body, I have notice that idle is smoother with less fluctuation when the compressor kick on and off. Also, the throttle is much more responsive, whereas with the old one it often felt slightly bogged down. After doing this repair I now definitely believe that my old one was on the way out, so I am glad I did this so my wife will have no worries when she is on the road. Of course the bigger question, and rant is, why do these keep failing??? Greg Quote Link to comment Share on other sites More sharing options...

Granted a number of them are, but I must be one of the lucky ones as I have never had one fail in over 600,000 accumulated miles on all three of my Edges. It is bad luck for sure that you were having issues. You at least caught it and corrected it in a preventive manner to keep you wife safely running down the road. 2 Quote Link to comment Share on other sites More sharing options...

Especially around where the butterfly valve closes? 1 Quote Link to comment Share on other sites More sharing options...
akirby Posted November 6, 2017 Report Share Posted November 6, 2017 Ford has sold millions of vehicles with that throttle body. If it was widespread there would be tens or hundreds of thousands of failures. I think it's safe to say the failure rate is pretty low - probably in the 1% - 2% range - but that still adds up to a lot of individual vehicles. 2 Quote Link to comment Share on other sites More sharing options...
omar302 Posted November 6, 2017 Report Share Posted November 6, 2017 I believe Ford's main issue with the throttle body was the fact when it failed & vehicle entered limp mode, no DTC would be saved after an engine restart, leaving customers frustrated when a dealer would not be able to diagnose the problem without being able to see the symptoms. This probably elevated the concern. 2 Quote Link to comment Share on other sites More sharing options...
gtyates Posted November 6, 2017 Author Report Share Posted November 6, 2017 How dirty was the old Throttle Body? Did it have a lot of buildup? Especially around where the butterfly valve closes? Actually it was not very dirty at all. I have seen worse on my Sport Trac. 1 Quote Link to comment Share on other sites More sharing options...
gtyates Posted December 9, 2017 Author Report Share Posted December 9, 2017 (edited) Ford had a replacement campaign for the throttle bodies. Did you run your VIN through your local dealer? You might have been able to get it replaced for free. I checked using the Ford Owner site. They only 2 things that show up for my VIN are the APIM extension warranty and the brake booster warranty.
