OBD 2 Code P0456

[soloecho2]

On my way to work this A.M. the check engine light came on no noticeable sound or driveability issues noted. Aside from the gas cap issue is there something else for me to look into. Cleared the code I will fill up in the morning and monitor and let you know.

soloecho2, the other thing could be a leak somewhere and I doubt that, unless you have history of the car somewhere in a corrosive environment.

kompressorgpl, the "Gas cap issue" is usually just not tightening the gas cap on properly. So the fix is to just take the cap off and retighten it. The light then will clear itself over time. Which is probably the exact scenerio your Yaris went through.
