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.
