It is a simple valve that runs on 12V, you can bench test it with a small battery.

Hello JFP, I cleared the CEL code P0440 a few times and still returns, and today decided to check the purge valve by disconnecting it from the throttle body and tried to create vacuum by suctioning into the hose and you cannot pull any air from it.
However, after activating the valve with the Durametric if you suck into the hose you gan get air (actually strong fumes) but the flow of air is Not constant, more like the valve is open and closing, is this valve is supposed to work intermittent or constantly open? I also noticed that you can blow air towards the valve but again, not a constant flow of air (I am not sure if I am explaining this clear or not.)
Your comments will be (as always), greatly appreciated.
PS: If the valve is indeed bad, could I install one of these on line, like this guy did it?
because the OEM valve for the '07 987 costs about $450…

The valve should remain open while power is applied.
As for the valve in that article, I have no idea as I have never used one of them.

Hello JFP, a gearhead friend of mine mentioned that the vent tube could have some fuel inside as a result of over filling, if this is correct, could be possible for me to disconnect the hose at the other end and blow some air through to remove the fuel?
I traced the hose on the engine compartment and it runs down in parallel to the power steering tubes that go to the front of the car, do you know if this hose have a connection somewhere that can be open? If so, I could disconnect it to try to remove the fuel inside, is this sounds logical?
Thank you for your comments!

You won't find fuel in this line, but it can become plugged with carbon from the EVAP canister, so blowing it out with compressed air is a good idea.
This should help you with were the connections are:

JFP, Thank you for the diagram!
Before blowing compressed air through the vent line (at the intake plenum end with the purge valve energized), I should first disconnect the other end of the hose at the EVAP canister (by # 9) to avoid damaging something else, right?
Thanks again!
