    this obd2 trouble code table can help you understand the meaning of code.
    And for this code, you can try this:
    Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
    Otherwise, replace the gas cap, and/or
    Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary.

    I understand the meaning of the code. I did a smoke test to see which vaccum hose was leaking and none were. The car still smells like gas, and I dont hear any vacuum noise.
