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
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.
I recently changed my battery and when I connected the new one and start the bike I cannot throttle over 2000 rpms I turn the throttle and 2000 is as high as it will go. I was told to reset the ECM is that true and if so, How do you do it?
