Check engine won't turn off!

I have a 2004 Toyota Rav4 Automatic transmission with 134,000 miles on it. The OBD came up with 4 trouble codes; P0441, P0446, P0455, and P2418. 3 lights come up every time. The check engine, VSC TRAC, and TRAC OFF. The most likely solution was to replace the fuel cap. I have since replaced two fuel caps, a purge valve, and a filler neck. The check engine still comes up. Could it be the Vapor Canister?

It could be the charcoal canister. I would ask a mechanic to check it before buying a new one though.

I replaced the charcoal canister a few months back and the codes haven't come back on. Replaced myself too. Very simple replacement.
