Before you go crazy and begin buying parts, try tightening the gas cap a few clicks. This is typical when it's not tight and causes an evap leak. Then you might have to drive it 40 or so miles before it turns the light off.

Re: Cel Code P0440, What the hell to check?? (JRL)

Sorry to bump up old topic. Anyone has other ideas where to start? My sticker expires in a week or so... Got this code and not in a position to buy lot of parts.. is there any kind of diagnostic to pin point the problem?
