I would be glad if anyone could assist with how to correct this? Or at least an idea of what is happening?

Spellino: Favor to ask:

If overfilling has been the problem and all error codes go away simply w/ first click-off fills, kindly let us know here on YarisWorld. (Or what it does take to resolve the problem) Among other things, it would be good to know how robust our evap systems are.

Good luck and many thanks.
