Decided to search online for possible reasons why my engine light would come on when I came across this forum. Saw that I could have AutoZone pull the codes so stopped there. Was given code P0440 and told it was my evap canister and that the part was $299. Asked if I could still drive it and was told it was fine to drive just won't pass emissions until the canister is replaced.

Over the weekend I searched for more info and saw something about codes for topping off your gas and I had done that the night before my light went on.. Sorry I really know nothing about cars... Cleared the code but it came on again today. Decided to stop at the Jiffy Lube and have them make sure the air filter was fine. They checked and all was good, they gave me the codes that came up for them - P0420 and P0440. Local dealership here charges $99 just to run the diagnostics. Was hoping someone here might be able to give me some advise or information on possible reasons for these codes, cost to fix and whether I can really drive the car. You all seem to know your stuff and people have received good information so I would appreciate any help.

Check the pdf's above 2 posts. If the EVAP VSV hose is ok, then you probably have a CRACKED ORVR, this valve is in the top of the fuel tank. That should be the P0440.
The P0420 is a bad or inefficient Catalytic converter, not an 02 sensor ar anythig else.
I have attached a picture of a cracked ORVR, very common here on the west coast.
I recommend going back and reading this entire post, there is tons of good information from many TS members.
