enigma-2 Posted January 29 Report Share Posted January 29 There may be a couple of other checks that come to mind. Gas cap gasket or cap not clicked when being replaced. Wiring to the purge valve. Corrosion in the connector, Micky chewing on wires .. Quote Link to comment Share on other sites More sharing options...
1004ron Posted January 30 Report Share Posted January 30 CEL triggered again on the way home from work. Gas tank filler cap seal is good. Just read codes and installed a 3rd party evap valve.

enigma-2 Posted January 30 Report Share Posted January 30 Glad you found the fix. Personally I wouldn't have used aftermarket, but maybe its good enough. What brand did you go with? Always good to know if aftermarket works (and holds up.) Quote Link to comment Share on other sites More sharing options...
1004ron Posted January 30 Report Share Posted January 30 Generally I use OEM but for this being a non critical device and two OEM ones didn't last as long as I'd expect, I went with the DORMAN 994073 at around half the price from RockAuto.com. 2 Quote Link to comment Share on other sites More sharing options...
omar302 Posted January 31 Report Share Posted January 31 (edited) Strange you're having to replace it 3 times now. Glad your able to fix it easily though. Edited January 31 by omar302 Didn't read the thread correctly. Quote Link to comment Share on other sites More sharing options...

Stopped to gas up at Costco later and read the codes and got P144C - cleared codes and it hasn't reappeared. Looking to replace the evap purge valve for the second time on my Edge. Considering a Dorman replacement this time - $40 on RockAuto.com 2017 FORD EDGE 2.7L V6 Turbocharged Vapor Canister Purge Valve / Solenoid | RockAuto Welcome to the club of 17’ Edge Sport owners 2.7L EcoBoost who have to replace purge valves yearly :). I just did mine again as well. When my check engine light comes on in October/November it’s not even worth me checking the code anymore. It’s a different code each time, replacing the purge valve fixes it. This year my Autozone part was under a warranty. I didn't have to pay, they just replaced it. This one looks different than the others I have put on. We shall see :). (Lets update each other in a year lmfao). 2 Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted January 31 Report Share Posted January 31 Looking at your results, it seems that your fuel trims are a wee off. (Could be the way your car responds however.) Still, I'm kind of wondering if there isn't a small vacuum leak going on, on the evap purge line. (?) Quote Link to comment Share on other sites More sharing options...
