Installed my duals, pc3 and FCI intake. It shows code 12 crank position sensor? What did I do wrong, and how do I fix it?

Probably knocked the connector loose by the TB, check and make sure all of the wire connectors are tight...had the same issue with mine not too long back. Probably knocked the CPS connector loose while doing either the PCIII or intake install, the connector is just below the TB on the left side of the quad if I remember correctly.

Yeah, I am going to pull the plastics back off, to triple check the plugs. I hope that is the problem.

Try your connectors on the throttle body. 2 of them are the same, switch them around then try it...Happened to me.....switched them and no more code and bike runs great.
