    Hello everyone. My checked engine light is on, I had it check by Auto Zone and 3 codes came up p0442 p0441 p0446. This means Evap leak, I noticed many common issues on the internet with these codes. I was wondering if anyone had any suggestions on what to start with. I checked the gas cap for pressure, and under the hood for unattached hoses. Any suggestions were to go next without going to the dealer or a mechanic?

    Some stuff. Not a lot, just some.
    Start with the cap. Make sure it's tight. (sounds you already did this)

    Looking at the chart attached in the PDF below and if the gas cap is ok, it is probably one of the three VSV (vacuum switching valve) that controls the venting in the system.

    Here are the locations of the valves.
