check engine code

Hello all,

So my check engine light came on so I went ahead and purchased a reader from local parts store and this is what it returned.

P0440 Evaporative Emission Control System Malfunction

Ok so now what lol what is this code really stating to me. Sorry I am a moron when it comes to these things. I did read the forum on the engine codes and it listed what the codes were jsut like my tool did but for someone like me it dont really say much lol.

Thanks for any help

Yeah that was the very first thing I did check was the gas cap and it was very secure. I also have not gotten gas in a week so it has to be something else.

There is nothing wrong with your car, nor will it run bad, light on or off. If it does, then you need to look for a problem.

Perhaps it could be the type of gas cap that I have because there is no tightening that you can do to it. You turn it and it clicks then past that point it will just keep clicking.

Some time even if the cap is tight the seal around the cap may be bad try replaceing it with a new one from the dealer, have the light reset, if it come back on the have someone preform a smoke leak test to find the leak
