Good afternoon!  I have been looking all over, and to be frank, my knowledge of the Edge generations is pretty bad.  I have been searching all over to find a definitive answer for this P0456 error.  I have it, I cleared it, it came back.  Fine, so it looks like it is the Purge Valve.  However, I cannot find anyone that has a 2016 or 2017, or 2018 Ford Edge 2.0L that has had this problem that can show me what the part is. I have seen it on the side of the engine, back against the firewall, someone even said it was in the back near the passenger rear wheel. Can someone please tell me what I should replace first and can I even buy the darn part as I have also seen where people said it has been discontinued by Bosch and it cannot be found...  Please, I am begging you guys, please help me out!!!  I usually can find this stuff, but since I don't know if the 2013 or even the 2015 Edge use the same engine I don't want to take the chance and start tearing down the wrong things and then be completely screwed.  Thank you all in advance for any light/help you can shed on this aggravating issue.

you can test the valve when you take it out by trying to blow air through it from where the back hose connects (the one with the green tab) if you can blow air through then replace the valve.  Just had to do this yesterday, solved my issue, but I was getting p1450 code, but had the exact same issue with not starting after fill up.

also, check out the other threads relating to p1450 on here.

I ended up buying the purge valve assembly for a 2015 fusion and just swapping out the purge valve and reused my existing hoses.  It’s about $60 cheaper than the assembly for the edge.

You can check to see if the valve is stuck open by disconnecting the hose that feeds into the back of the valve and connect a piece of hose, try blowing air through it, you shouldn’t be able to is the valve is closed, as it should be.  If you can blow air through, replace it.

If anyone wants to save a few bucks you can buy the purge valve assembly for the 2015 fusion instead, and just swap the purge valve out reusing the existing hoses (I had to use a heat gun on one, but it wasn’t bad)

saved about $60 and apparently some hassle With hard to reach hose connections

Code didn’t clear right away for me either,  it was showing as permanent on the code reader, I cleared the ones I could (pending and don’t remember what the other way)  

anyway, once you clear the codes you can with the reader. You need to start the car, let it idle for about a minute, then get on the highway and drive for 10 mins between 45-65mph.  I just set my cruise to 64 and drove.  After 10 mins park somewhere and let it idle for about another minute before turning it off.  Turn it back on and hopefully light will be off.  Found those instructions on some Ford site, worked for me.

Just wanted to share my experience here as I just replaced the valve to clear the p1450 code.

I first started having issues with my gas gauge a while back, it was fluctuating all over the place, I could be sitting at a red light and watch it go from 3/4 full to 1/4 full before the light turned green, later it would slowly start climbing up.  Shortly after that the check engine light came in, code was p1450, only symptom I noticed was it took a couple of tries to start after filling the gas tank, otherwise seemed to run fine.  Today I finally got around to digging deeper,  verifies the purge valve was bad.  After I realized that you now need to purchase the whole assembly for about $140 instead of the just the valve for about $40 I was less enthusiastic.  I see Amazon sells the valve for  $25-$40 but reviews are mixed on those.  What I did find was the assembly for the 2015 fusion uses the same valve but has different hoses, but also is only $80 at the local auto parts store, and was in stock, since I already had it taken out I didn’t want to wait for a delivery for I bought the fusion assembly and figured I would just replace the valve.  It was actually really simple, I’m not much of a car guy but can be fairly handy then I need to.  The only thing that made it trick was the hose going from the purge to the check valve, it’s a rigid plastic tube that looks like it is heat shunk on the fitting,  I used a heat gun to warm it up enough to pull it off and push it on the new one, went pretty smooth,  I’m guessing it would be easier to just buy a different piece of tubing and used a hose clamp, that was my plan if the heat gun failed me.  Anyway whole thing took maybe 20 mins not including running to the store.

after driving it a bit the code cleared and check engine light is off.

now I’m reading about a recall from a while back for the focus, when the purge valve went bad the vacuum in the fuel tank would cause it to deform and cause issues with the fuel level reading, I really didn’t think the two issues I was having were related, but now I’m pretty excited to see if that issue cleared, I’ll have to drive it for a few days to know for sure because the gauge issue wasn’t consistent.  
 

one question I have if anyone knows.  Was the deformation to the plastic tank a permanent deformation, or would it go back to normal when the pressure normalized?

i’ll try to update when I decide if the fuel level issue is cleared up too.

maybe Ford needs to extend the recall to other models that apparently use the same bad parts.
