I did some searching and couldn't find many posts on both these codes. But from what I am seeing it seems there may be a vacuum leak. I just replaced some vacuum lines up front under the battery and it seemed to have fixed the issue. The light stayed off for quite some time. Then this morning it came back on and these are the codes. Is there an easy way to test for a leak in the vacuum lines?

2000 ES300 with 70000 miles. I have recently replaced the gas cap with a stant and fixed the vacuum lines that were not even connected. Any help would be great. thanks.

Here you go, and the guy did it with one hand:

That doesn't look hard at all. I probably won't get to it for a bit. What's the worst that will happen if I don't change it immediately?

Really it's your emissions system so your gas mileage may go down a bit???

I'm going to have to do this since I just changed the whole charcoal canister after getting the p0440/p0446. now I'm getting p0440/p0442
