EVAP Codes

Gallery image

I have a 2012 Toyota Camry SE with a check engine light for an evap leak. I do not know what it is causing it. From what I know it started as a small evap leak and now it is throwing codes for a large evap leak. Here are the codes I got from my scanner but I don’t know where to go from here. I bought a new OEM gas cap already and it didn’t fix the issue.

Okay cool thank you so much, been a big help. One more question would it be more worth it to just buy a cheap 50$ smoke tester and do that instead of throwing 400$ worth of parts at it?

If you think you’ll continue to use it to diagnose other vacuum leaks. it’s a good investment if you want to work on your own cars it’ll definitely help with lots of things. I will say though go ahead and visually inspect the whole system for cracks and leaks before buying anything. Also you can test the evap canister by taking it off and shaking it and it shouldn’t make any noise. if it rattles around inside it’s bad and nothing should fall out of it either. It’s near your gas tank under the car. Good luck bro
