check gas cap and make sure on good, if possible find another one to try on car to see if that works clear codes before trying(take neg cable off battery for approx ten minute) or might have leak in vaccume line or canister

While looking for the location of the vent/solenoid for you, I came across a blog that said this error can be caused by a loose or faulty gas cap. You may want to look at that first and possibly solving the problem. Replace the cap, get autoparts store to reset the code and see what happens.

There is a solenoid that open and closes with 12 volts, usually located close to the fuel filler tube area. This open to allow you to fill your tank, then closes after some inputs for the computer are satisfied, and then a pressure sensor verifies the system is working. First, make sure the cgas cap is tight, and if the light doesn't go away in a couple days of normal driving, get the solenoid checked.
