Need a faster answer?
How soon did the error code come on?
Couple things to check
1.) loose or bad Gas Cap systems are sealed now for pressure if your cap is loose it may through a code on some models.
2.) ***Are you putting in E-85 fuel in a NON-E-85 rated car? That is a No.. NO.... NOOO... reason your system needs to be beefed up as more Alcohol means you need a different computer to adjust for it and fuel system in general.

Hope I helped
