CEL, took it to dealer for first time since purchase

I had the CEL on for a couple days so I took my car in for a dianostic to see what the problem was. I inspected the engine and couls find nothing wrong and car was running great. It took about 2 hours for them to figure it out, it cam back with codes of 440,441 and 460. They checked the components associated with these codes and found no known problem. The said Camry's do this to sometimes and hopefully Toyota can find a fix to this annoying problem. They logged the imformation on my account and sent me on my way. I was very satisfied with my first visit but I'll keep my dealer visits to a mininmum.

Don't be surprised if the CEL comes back on and generates the same code. It is most likely coming on because of the CAI, if mine comes back on again, I'll probably take it in as well.

i had those same codes, they ended up replacing the rear VSV. It's your evap emissions system. coulda been a loose gas cap.

My TRD buddy is saying to just replace the gas cap to eliminate that being a problem. I told him I was turning the gas cap at least 5 clicks and he was saying I might have messed it up or even cracked it.

He was saying all you needed was 3 clicks, but I recall the dealer I bought my car from saying it was ok to click it more to make sure. He said at the time people were coming in with the CEL on because they did not tighten the cap.

Who's right?

Btw, a mechanic friend was telling me one of my hoses could be leaking but I did not get the chance to bother him to check it out. He stated at first the gas cap, but after my gf told him I had a CAI, he automatically deduced it to the intake.
