This issue started back in July, so I purchased a new gas cap (to replace the original cap) and turned off the CEL. The code came back about a month and a half later, so I replaced the purge valve located on the radiator fan shroud. This morning the code reappeared, and I was wondering if I now needed to replace the other purge valve (which is the shut off valve for the EVAP canister)? Any suggestions would be greatly appreciated. Danke :)

    I did some research and someone mentioned that "blockages in the fuel vapor hoses/tubes (EVAP canister tube, canister purge outlet tube or return tube) can cause this problem (code PO455) as well. When the car was on the rack for the (second) steering rack (which was thankfully covered under warranty), I noticed an outlet hose that faced to the ground and had some leaves clogging it. True to form, I forgot to clean it out. Perhaps I will tackle this first, and see what happens. Thanks again :)
