Q: 2009 Harley Ultra Classic w/25K no past problems in the past, but on 07-12-14. I had a problem with what I found out and is called “Limp Mode”! no throttle response at all other than running at idle. Error codes I found on the bike were; P1511 & P2135. all having to do with the Harley throttle control. I did some looking on the WWW and found most who had this problem removed the connector “pin” plug from the throttle body, cleaned out with cleaner and added “die electrical grease” and the problem went away.
It’s running great now.
Just asking if this is “The Cure”?
Thanks Harold D
A: Yes, We have come across this problem a few times and that seems to be the fix. Other times, however, guys make a mess of their harness when attempting to install a set of handlebars and the Harley throttle control. That can also cause that problem.
