Are showing up on my car. What is the problem and how can it be resolved? I took my car for my annual car inspection. The emission testing did not pass because of the codes above.

They are evap codes. You need a shop with a scan tool and a smoke machine to test the components for failures.

It is not an easy diag, takes time to find the exact issue
