    Hello,everyone I have a 99 Toyota Corolla CE with CEL codes P0440,P0441,and P0446.There are no drive ability issues.Starts up fine and runs fine considering a few other things I have going on that don't stem from these codes at least I think.(rattling when I accellerate and a whirling sound coming from what sounds like the tire area).Has anyone had any experiences with these codes and what to do to fix these annoying lights on dash....

    It's a problem with the EVAP System Vent Control Circuit

    Check the following first...

    - EVAP system hose leaking
    - Foreign matter caught in fuel filler cap
    - Incorrect fuel filler cap used
    - EVAP canister or fuel tank leaks
    - Vent control valve harness is open or shorted due to Missing Fuel cap
    - Faulty vent control valve
    - Fuel tank leaking
    - Fuel filler cap remains open or fails to close
    - Vent control valve circuit poor electrical connection

    Find out how the EVAP system works and check each component in it.
