Engine light came on after washing the bike. I've heard that it may be that a sensor got wet. Anyone have experience with this?

Have a 2012 Victory Vision that is throwing a code. Check engine light comes on when idle, goes away when accelerate and comes back when RPMs drop. Does anyone know why this is happening?

I have a 2003 vegas ,the speedometer quit working and the check engine light comes on. I've seen where others have posted same issue but never said if they got it fixed and what the problem ended up being?
