I did some research and some people say that this problem is caused by a spider's nest blockage somewhere along parts labelled #2, 10, 12, 14, or 20. I decided to get my hands dirty and take a look. After removing the entire EVAP canister, I checked all the hoses and nothing was blocked (couldn't really see inside part #20 though).
Other research indicated that by replacing parts #1 and #2, the problem will be fixed. But for others, it didn't solve the problem. So I decided to do some troubleshooting before I spend any money.
When I turned the ignition to II, I didn't see the valve move at all, is it supposed to move while in ignition II? (the above tutorial doesn't specify what's supposed to happen)
I then disassembled part #2, took out what I believe to be the vent shut valve, and it didn't seem to be damaged or anything (pics below)
Now I'm stuck, I can't tell if the vent shut valve is busted (if it even IS the vent shut valve. looks like its fine though) or if the vent shut valve is actually inside the canister and therefore needs replacing :donno:
Is there anyone that can verify my identification of parts? Anyone solve this problem already?
Left (Canister), Right (Dust Filter - vent shut valve inside?)
I think that piece I pulled out is the vent shut valve
There is a moving valve in the center, you can see the botton of it right in the middle there
And there's the top of the moving valve part in the center

It may move when you move it, but will the valve move when power is applied?
Well I tried plugging the valve into the 2-pin connector while the ignition was in position II, and I didn't see it move at all. But maybe the valve is only functional when the car engine is on, and when its connected to the rest of the evap system?
My car ('04 TSX) is throwing code P2422. Car drives normal, no other problems. I have not yet crawled underneath the car but how can I get access to the EVAP canister shown above? Do I need to lift up my car from the rear? From the schematics it look like it is underneath the rear seats behind the fuel tank?
Any help would be appreciated.

Update: Since my original post I havn't done anything to fix this problem. Anyways, my battery died cause I left my fogs on over night, so I jumped the car and as I was sitting in my car lightly revving the engine to charge up the battery, the engine light for the EVAP canister code went off :s
I have yet to drive the car for a longer period of time to see if the light comes back on
