Need help with error code
I noticed my check engine light coming on for a few seconds after starting my 2008 Ultra and going off. Pulled the code P2101 from the diagnostic check. The description for this code is: EFI Motor Circuit Range Performance(Actuation error). Can anyone shed some light on what this means and what I need to check. I did try to clear the code several times and it won't seem to go away. I do have a Thundermax tuner on my bike but I have been able to clear trouble codes before. Thanks for any info you may have.

I had p1511 and p2101. Pop up on my bike one time right after starting the bike up and was in the middle of bfe. Bike went into limp mode. I shut the bike off started it up and it was still there in limp mode repeated a few times and let it sit for a few minutes. Started the bike up and it was gone knock on wood hasnt happened since. I had the dealer pull the codes and they said basicallt it could have been anything from the tbw to the servo motor for the throttle body. Do you have aftermarket bars? I have yaffe bars and there could possibly be a bad wire connection somewhere. Before checking that try and pull the plug to the servo motor check for corrosion if so clean the connectors and put on some dielectric grease reconnect and see if that works.

I still have the stock bars but I did replace the grips a few years ago. I did read that there was a problem with the plug at the servo motor on these bikes so I will check that out. Thank you for the advice.
