I believe that code is for a small evap leak. It could be anything from the fuel cap onward, filler neck, charcoal canister and the vapor lines that run all the way to the purge valve. If its not that line, best way to find the leak is to smoke test it.

Lots of possibilities, but just as another idea work with the fuel tank access hatch recently? The shop who worked on mine pinched part of the gasket causing a very small leak.

Recently i went to the dealer to get a recall done on this for the fuel leak (I'm Not exactly sure what they changed I noticed new fuel lines). Afterwards I tried asking them exactly what they've changed and they wouldn't tell?! about a couple days later that code popped and doesn't want to go away.

If you went to the dealership to have that recall fix and the code started after... take it back to the dealership and tell them to figure it out. They probably left something loose or a hose isn't quite seated or something like that.

i wanted to do that but i felt like they're going to say "oh your car has aftermarket parts that could be causing the code" so I'm hesitant to do so.
