P0440: Evaporative Emission Control System Malfunction

[bennettmayo]

SES light came on yesterday. Had it read today, turns out to be P0440: Evaporative Emission Control System Malfunction.

I know it involves the fuel system, and I think I may know the reason. I changed the fuel filter on sunday. Is it possible that I didn't tighten it down enough? Woul that cause the code? or is there maybe another place to look for the source?

When this code pops up it means that there is moisture in the fuel system so it need's to get evaporated go to the dealer they will get the job done right so u don't have problems.
