Cel p2418

Please help: check engine light code P2418
Hi,
please help...
2015 F150 2.7
Code P2418.
evap switch control valve circuit open
I replaced the Vapor canister purge valve already:
After replacement, the CEL went away immediately.
Driving the truck has never changed, with or without CEL on.
Now after 2 days the light just came back on with the same code P2418.
Did I replace the correct part?
What should I check next?
Your help is much appreciated. Thanks

Thanks. I did read another post about three same issue. From that it said that the VBV is on top of the fuel talk. I probably have to drop the tank and see if I can see anything going on.

Just wondering, after replacing the part, Did you have the code cleared
Mine did the same code, replaced the part you did, and had to clear the code after
If you dont, it will keep coming back after a day or so.
Autozone should be able to clear the code for ya

It came with my Workshop Manual and Electronic Schematics that I bought from
https://www.factory-manuals.com/
It was considerably less expensive when I bought mine.
Or you can go here, but a 72 h subscription for $21.95, and download your own.

Did not fix it
my alarm is a switching control valve connection fault all the connections seem OK I need help. Ford is already wasted $800 in my money. They don’t care all they’re gonna do is replace parts. I can do that too.
