When you have P0440, P0441 and P0446, it is a very good bet that the fuel cap was loose, or the fuel cap rubber seal is compromised. You will get all three of those codes every time that the cap is loose. Always make sure that the fuel cap is as tight as you can get it after you refuel.

Sometimes it will be written in ownership books in your glove compartment, if not any lexus dealership should be able to give it to you, some dealerships may want you to come in a prove you own the car.

You replaced the wrong sensor. Here is a link that can further explain how to trouble shoot this problem http://us.lexusownersclub.com/forums/lofiversion/index.php/t14194.html
Check for Vacuum hose for leak,crack or blocked first then, Vacuum switch Valves for vapor pressure sensor next to the Evaporator Charcoal Canister rear of the fuel tank. Charcoal Canister crack or damage. But mostly likely Charcoal Canister and vapor pressure sensor replacment. Tell us the result.

po305 is related to missfire on #5 cylinder
po440 is related to fuel tank pressure
pO441 is for evaporator purge flow malfunction
po446 relates to vent control valve electrical circuit malfunction
missfire is seperate from the other codes
as for the other three codes replace the vent control valve solenoid located near the charcoal canister the oth3er codes can relate to a faulty solenoid
after replacing light will only go out if you clear through a scan tool or three drive cycles of over 10 min each
