In have a 2008 Ultra Classic bone stock. It has just shy of 30,000 trouble free miles. Today I was out riding and lost power. Cruising 65 and lost all throttle response. Engine light came on and it went into limp mode only able to go around 2000rpmwith no throttle response. The codes it gives are P0505; P1511; and P2135. It is not under warranty and I would like to fix this myself, I have the manual. What do I do next?
Thanks for your help,

P1511 is EFI power mgmt mode. P2135 is TPS correlation error. Don't see a P0505 on my list. Think these bikes may have an issue with the wiring behind the air cleaner near the throttle body, but I can't remember the specifics. Might do a search on here as I have seen similar problems before.

 

I had that happen on My 08 UC about a year ago. Can't remember all the codes, but I know P1511 was one of them. Still don't know what happened, but I think I hit the kill switch by accident. Shut it down and restarted and could'nt go above 2000rpm. I then cleared the codes, and started it back up and all was OK. Have'nt had any problems since. Have done about 6K miles since that happened.

 

Now that I think about it, I had the TPS correlation error also. So try clearing the codes and see what happen's

 

same on my 07 idol screw came loose and backed out threw the tps out of wack.the nonexistant heat issues softened the locktight on the screw , dont try and fix this one yourself it has to go on the computer to set the idol screw.

 

Sorry, don't have anything to add other than to say that I will be watching your thread closely for obvious reasons. Thanks for sharing, I may learn what to do when/if it happens to me.

 

there have also been simmialr problems with the set screws on the throttle plates coming loose.

 

I also have an 08 ultra and was wondering if this happens to me how do I clear the codes ?

 

Thanks for all the replies, I might have to take it in to the dealer.

I am subscribing to this also. I have an 08 as well and would like to know how to clear the codes if this happens to me
