Yes I had the person at Auto Zone clear the codes and I put a new gas cap on. After they cleared the codes and I put a new gas cap on it was fine. I used the car for about 2 weeks and then filled the tank with gas about 1 week ago and now the vehicle is at about a half of tank of gas and the light came on again. I just went out and checked the hose again. I even took the top off the air box to verify the hose was connected. As far as I can tell the hose is connected. Will it help to disconnect the negative battery cable? Do you know will that clear the codes and turn the check engine light off?
Thanks,

Ok in follow up to my above message, I went to Auto Zone again and had the same OBD reading (P0440 and P0446). Checked the hose off the airbox and it is attached. Put a new gas cap on. Reset the the check engine light and it was fine for a few days. Filled the car with gas yesterday and light came on again later that day.
Not sure what else to check? Does anyone have experience with these two code readings. Could it be a bad tube or seal, bad vacuum hose, something in the charcoal canister, Vapor pressure sensor??? Just looking for some input on what to check next.
Any help would be greatly appriciated.
Thanks,

With all the hoses under the hood that can cause problems, let's make sure we are talking about the same hose. The one I am referring to is connected to a metal tube that comes up along the fender well under the brake master cylinder and in front of the fire wall. It is not easy to see and you have to have the top of the air cleaner off and your face has to be directly above the master cylinder and a bit to the left as you are looking towards the passenger compartment. It helps to have a flashlight. My girl friend had her oil changed again last week and last weekend I had to reconnect the hose.
Hi RonRX300,
Thanks for the reply. I am almost positive I have checked the correct hose. Just to be sure when you lift the cover off the air cleaner it is attached to the back of the cover of the air cleaner and a also to the metal tube that comes up from along the fender back to the fire wall. You for the most part cannot lift the cover off the air cleaner very far if it is connected to the metal tube. I have opened the gas cap again and also noticed there isn't that swooch sound so it could possibly be something else in the evap system.
Thanks and I will keep digging into it further. Don't want to give up yet and take it to a mechanic.
