Answer 1

HI there,

Because its a large evap leak code, I would make sure the right fuel cap was on it, then if the code reappears have a smoke test done to locate the leak. This could be a problem with the fuel pump O ring or an issue with the pressure sensor causing the problem so both should be tested.
