They should clear on their own if the problem is not recurring, but it can take quite a while depending on the code and the amount and type of driving.

But it's faster to clear them and see if they come back.

I had some issue that needed fixing, coulda been a check engine light. I was told to put 50 miles on it before getting it smogged, the onboard computer needed to recalibrate itself. My truck had been running normally before and after though.

Hope this is your fix instead of a rerun problem.
