I looked it up and the vent valve and purge valve are listed as one in the same on this car
Hmm, I am not sure about this. The vent valve is located close to the canister itself (should be close to the filler tube above parking brake wire right/passenger side) , the purge valve should be located in engine bay close to the power steering reservoir.

Here is proof, unless ALLDATA is wrong and my experience of these very frequent flyer cars of the day to visit my bay is wrong they should be located right where I said they should be. So here are a few snapshots.

What may have you confused is that they call the vent valve a vent solenoid/valve.

Now the part you showed all I see is the one that has little green cap on it I believe it's the spot you hook smoke machine?

A second pair of eyes -
I see you changed vent valve, What is the issue now?

Do you have a scanner - to command valves open closed - Observe FTP sensor?

We had it put on a pro scanner and could not figure out what was going on as it's throwing such a generic code if the guy brings car back over we are thinking replace the one on top the engine and check lines again the smoker only found the one under car the case was leaking I'm not that good with this type of stuff

Could be the pressure sensor in the tank, I had one a while back checked and replaced a few sensors but never found the problem. I did see pressure differences on my Matco Determinator, (OTC Genisys) but dealer said sensor was stuck. Long story short $215 later it is fixed dealer sensor $80 online $32.
Oh well I know I saw a reading fluctuation when I removed the gas cap per Alldata troubleshooting.
Thanks
