Code P0440
The Check engine light came on last week in my 97 Cavalier. I took it to have the code read and it came back as P0440...the only explanation it gave was a fuel system failure.
Anyone have any idea what a code P0440 is? Or what it could point to? Thanks for your help! By the way, the car runs fine and, yes, the fuel cap is on tight...

Re: Code P0440
If your certain you gas cap is tight, then you might be in some trouble. You probably have a leak somewhere in your fuel system. Check your lines and hoses for leaks.
