Check engine light keeps coming on for no obvious reason! Ideas?

[RobKrue]

I have a 2011 Can Am Spyder RT and my check engine light has come on 3 times in a very short period of time. I have had it in the shop twice already. The shop has changed a few things on it, but it still keeps coming on. Has anyone else had this problem?

Kind of a default response; Double check battery connections clean & tight.

Check engine basically a “catch all” light , shop did work & still coming on learn how to pull codes , might want
second opinion somewhere else.

Pull the codes the next time it does it and someone can point you in the right direction.

My 2021 F3-T did that and it was the knock sensor... There were no codes I could pull up that i could find.... My dealer found it and switched the knock sensor out.... 1000 miles So far so good....
