    Default Getting P0441 engine code on 1999 Corolla

    My 1999 Corolla with about 40,000 miles on it over the past month has
    been registering P0441 that represents "EVAP Emission control system
    purge flow fault." Less than two months ago I had to replace the
    starter on this car because of solenoid failure and read that EVAP
    solenoid failures are listed reported as the worst problem with this
    car. I further read that most of the time the charcoal canister
    located near the gas tank has to be replaced if the car is taken to a
    dealer for repair. Anyone have experience with this? The car rarely
    gets out on the highway so someone suggested a long highway trip might
    solve the problem if it was just a matter of clogging. All ideas
    welcomed.

    Try tightening the gas cap a minimum of 6 click. It should solve the
    problem in one or two starts. If not, the next cheapest thing is to find a
    new cap; if you have vehicle inspections where they check the gas caps for
    leaks, take it to one of those first.

    If this doesn't resolve the issue it's time to delve deeper...

    Where is the purge valve relative to other parts of the engine and is
    it something someone without a lift can replace? Thanks!

    I'm not sure exactly where the purge valve is on your car, but it should be
    somewhere between the charcoal canister, which should be on the right hand
    side of the engine compartment as viewed from the front of the car, and the
    throttle body. The canister will have a couple of thin hoses on top and one
    on the bottom. Follow the hose that goes from the charcoal canister to the
    throttle body; the purge valve shoud be along that hose somewhere if it is
    not built into the canister.

    You can get a diagram at autozone.com. Look up the repair guide for your
    car, then look for emissions, then look for evaporative emissions for the
    7A-FE engine.

    Clear the codes, and turn the gas cap until it clicks several times, and
    check codes again when the light comes back on.

    The Gas Cap is a device that has to seal or the evap systgem will not
    function properly. You could have other issues to deal with, but the gas cap
    is something you open and close every 300 miles or so. Since it is a
    Operator Interface, it is imperetive to remove operator error as the cause
    of the problem. When you put the cap on, turn it past the ratchet so that it
    clicks 4 or 5 times. If your habit is to turn it until it stops, you may not
    be setting it fully, and the result can be an Evap System Error.

    This particular code is for the Purge Valve, and the cap may have nothing to
    do with this at all. But, on the other hand, the system maintains a very
    delicate balance and if the cap is not sealed well, the balance can be
    thrown off and the purge valve can be affected. Before you open your
    checkbook, make sure the gas cap is sealed well and check the codes again if
    the light comes back on.

    The beauty of this problem is that it won't affect your car while you drive
    around troubleshooting the gas cap.

    Tightening the gas cap properly or improperly will not set or clear P0441.

    I'm getting the same code on my 1998 with 120k. Able to reset code pulling
    EFI fuse for at least 10 sec. (from Haynes repair manual). Went to Autozone
    to get the code read out (free) and the first thing they suggested was
    replacing the gas cap. Replaced with after market cap but got error again,
    went back and former Toyota employee working there said I needed OEM cap so
    took cap off my Sienna van and had the same error.

    The error doesn't come on right away it may take a couple of days. Saw a
    connection to the air filter in the manual and it all seemed to start after
    having the oil changed so thought maybe the filter cover wasn't seated
    properly. After fooling with that still had the same problem. Also replaced
    one little hose coming from the metal tubing from the canister ( which is
    inconveniently located behind the muffler) to the air filter assembly but
    that wasn't the problem.

    Was investigating replacing the purge valve ($80+ new from Toyota canister
    $200+) then took it on road trip as error wasn't effecting operation. The
    error code cleared itself when on the trip, now suspecting air leak
    somewhere as high speed driving seems to clear error so will probably try
    and replace some more hoses.

    The shotgun approach where you replace parts without checking them can get
    very expensive, especially when parts are replaced that would not throw the
    code even if the part were bad. A more cost-effective approach would be to
    check the component identified by the diagnostic trouble code (DTC), which
    in the case of P0441 is the purge valve for the evaporative emissions
    canister, sometimes referred to as the charcoal canister.

    Yes, I spent all of about $11 so far compared to the $80+ cost of the valve
    but I enjoy trying to repair things myself and call outs from autozone for
    the error code did mention gas cap, hose leaks, as well as the valve and
    canister.

    My check engine light has not come back since clearing the P0441 code
    5 days ago. I'd read overfilling tank can lead to this code that is
    something I frequently do so will run my car towards empty before
    refueling as long as the light stays off. I realize most of the time
    problems are more complicated but hopefully mine will prove to be more
    basic.
