Default P0447... AHHHH D@MN Evap Vent Valve!!

I can't get this thing to go away, I relocated my canister for my Evo2 before, and it never threw this until I uninstalled my TN kit and now it won't go away!! I checked everything, the valve is seeing power, fuses okay, hoses are fine. Is there any way we can just remove this thing and do some kind of bypass? I saw someone fabbing up a PVC canister and saying they didn't throw any codes.... Anyone have and ideas?

This and the P0037 are pissing me off because I keep getting them regardless of what I do....

Double check the lines for holes/cuts. Also make sure you didn't cross the two larger hoses.

Is it possible that the purge value upfront behind the plenum can be the cause of this, I hooked it up just like it is supposed to be stock.... but maybe I should swap it out?

Check! no holes or cuts, but good point about crossing lines never crossed my mind I will try that tomorrow... Thanks Matt!

Could be the evap valve up front behind the plenum. I think I have an extra one in the garage.

Off topic slightly, but what could cause that evap valve behind the plenum to TICK? Mine ticks relative to the throttle position. I have the harness unplugged for now so I don't have to listen to it...
