On my 2008 electra glide I have a trouble code of P1511. Did not have any other codes. I know the code has something to do with the throttle control actuator, and it put me in the limp home mode. After a few starts I got the bike to run better and made it home. Would a bad twist grip sensor trigger the throttle actuator to give me the code P1511. I have checked for any loose or dirty wires and all seemed good.
