If the fix isn't as simple as replacing the fuel cap, then there is a diagnostic process to determine exactly which component has failed.

This failure should not affect the drivability of the car and should not pose much risk of causing further damage. The car should be ok to drive until you can get it repaired.

I replaced the gas cap and cleared the code. Drove about 50 miles and it stayed off.
