    My 2004 Toyota Tacoma with a V6 engine has the following codes P0441, P0442, P0446
    Any suggestions on what could possibly be causing these three codes.

    These all appear to be related to the fuel tank purge system. Could be the valve itself, could be a cracked vacuum line.

    I'd start with a new Oring on gas cap and replacement of vacuum hoses with thick wall silicone. You can test the Vacuum Switching Valves.EEBFF8B4-ACBA-4316-A854-9F2FD05AC2A0.jpg
