Iv owned the car for about 6 months now, and Iv gotten a check engine light twice with the code of P0021. The car runs fine and all the fluids are good. Has anyone had this code and what does it mean?

I had the code when I pulled her out of winter storage. Took to dealer and was told because it was sitting so long. Didnt come back on after that.
Maybe a light "technical tap" may help.
