Vapor Canister Purge Valve - 2001 Toyota Sequoia

How to locate, remove and replace the vapor canister purge valve on a 2001 Toyota Sequoia. This should also be applicable to other early models Sequoias. The tools you will need is a 12 mm socket and ratchet, needle nose pliers, and a small flathead screwdriver. My current check engine codes are P0440 P0441 P0446, and I&hoping this will solve the issue. The part number you will need is 911-488 or PV725 i believe they are the same thing. Hope this helps!
