EMISSION CODES OF P0440, P0441, P044 ARE SHOWING UP ON MY CAR. WHAT IS THE PROBLEM AND HOW CAN IT BE RESOLVED?

2000 Lexus RX 300 • 15,800 miles

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
