'07 ES 350 Engine and VSC Light - Error Codes P0451 & 455
Good Afternoon - first time here. Any help will be greatly appreciated. Just turned 80k and recently noticed a bit rougher at idle. Other than that all has been fine. Plugs, etc. all original. Autozone ran the scan which turned up the above stated codes. They are defined as Evaporative emission control system pressure. He said it could be a loose gas cap. Checked it and its tight as a drum. Looking forward to your suggestions. Thx in advance.

I had a similar code on my Sienna van a few weeks ago. I reset the gas cap, cleared the codes and it hasn't come back. I would guess that if you see it a second time then it's something to have a pro look at. Did you have them clear the codes?

Honestly, I'm not sure. My next door neighbor has one of those $25 OBDII readers from Amazon. I borrowed his to reset the codes. I don't see why Autozone would not...
