Default DTC P2422 (EVAP canister vent shut valve close malfunction)

Dear Smarter-Than-Me,
I got this code: DTC P2422 (EVAP canister vent shut valve close malfunction) in my 2008 Honda Accord. I read the technical service bulletin and it says there is spiderwebs most likely causing the issue as they get in the EVAP vent hose or drain box. My questions is, what does the EVAP canister look like and where specifically is it located? The TSB says it is above the driver's side rear subframe. Am I blind or is it right in front of me? Can anybody explain what it look like so I have a clue what I am looking for?

Also, for anyone else having the same code, here is the TSB I found online in full:

Actually, I just found the actual TSB with pictures of the procedure....Here is the link if anyone cares.
http://mordor.rutgers.edu/accord/tsb/08-09%20MIL%20P2422%2008-087.pdf thanks. This Honda-Tech site is great.

Also, I ran through the procedure and sure enough, there was spider webbing blocking the valve. Cleaned it out and no more alarms. So, the fix works....
