I have a 09 Ultra with 10,000 miles on it. I baby the bike most of the time except for last week I was riding it more agressive and the check engine light came on and it went into lymp home mode. I checked for codes and it came up with P1511. The manual says it is the Throttle Grip Sensor. I replaced it and cleared the code. Same thing happened again after around 100 miles. Any ideas where to go from here ?

Take it to the dealer and let him check it out.

My solution to this nightmare after 3 weeks sitting at Harley...

Behind air cleaner facing the rear is a connector. All they did was unplug it, clean it up, and replace the di-electric grease that had washed out.

The tech service bulletin that someone earlier in the post directed you to explains this in detail.

Hi everybody, this is the "newbie" Giovanni from Italy.
I found this forum while surfing for information about a problem that occurred yesterday to me. It seems quite similar to what you are talking about: while riding to work, the "check engine" light suddenly turned on and the engine suddenly turned into limp mode.
I called the dealer and he told me that he needs to plug the computer into to bike to check it. I haven't tried to get the error codes from the bike (I'll do it later), but I am quite sure I'll find the "infamous" P1511 and P2135.
My bike is a 2009 Road King with some 14k miles on it. The problem had never shown up before.
I feel a bit depressed because
a) it looks like the problem is a common one
b) I already had a starter problem (it needed to be replaced) a few months ago, so putting the money into bike repair is becoming a standard... :-((((

I quote myself to add an information: after taking the bike home at no more than 40 kmph, it rested the whole day. I then tried to turn it on again in the late afternoon, and it seemd to work properly, with neither engine light solidly on nor "limp mode".
Does this suggest you some more diagnonsis?
TIA

It just means the current problem (or code) went to a historical code. You still must correct the reason why it happened. Using the self help section, perform a WOW test to see what historical codes you have stored. Don't jump to a conclusion before you extract the code(s).
