EVAP (po441)

2002 Tacoma, base cab, 5 speed, 2.7liter, 4x4

Now comes the tricky part, trouble shoot/repair the EVAP (po441). I have already searched here for info, but didn't find an answer in archive, I looked at a bunch of YT videos to no avail, I need to speak with someone who has experience with carbon canister VSV's and bench testing of same.

I found the VSV on the canister (located under the box, between the rear end and gas tank). I bench tested the VSV solenoid and found it was not actuating, it was stuck in the open position. As it stands, Toyota does not sell the VSV separately, the entire canister must be purchased. But...I did find many VSV's for sale on line, what I don't know is which type I need.

Do I want one that is closed when not energized, or do I want one that's open when not energized?

Because I found the one on the truck stuck in the open position I have no way of knowing if it stuck while energized or not.

A lot of reference, but not the answer I'm looking for.
