2010 Yaris- what is this part?

[TYaris2010]

Picked up a 2010 Yaris today.

Wondering what this part is on the engine? See image circled in red.

Tried looking at the Village Toyota website but no luck.

Dealer cleaned the engine before I took the car home and there was a greasy film on this...wondering if they left some soap/engine cleaner on it. Wondering if its part of the emissions system? have never seen a 'cannister' like that on any engine I've worked on, unless it was hidden and not as visible?

Will prob have more questions in upcoming weeks. Thanks.



Sorry, I dont know if this is the right subforum for this question? I have no idea what generation Yaris the 2010 is. Currently have a 2003 Echo....will be selling that off soon replaced by this 2010. Thanks.
