I have an 07 FLHRS that I purchased used, 1 previous owner. I was changing out the air cleaner system the other day and noticed that the TPS was unplugged and each fitting was plugged with a cap, so it was obviously intentional. I know the previous owner was not knowledgeable enough to do it herself. I guess I am not either seeing as I left the HD technician field in 2001. But knowing what I do know, I can't figure it out. I have searched google and the forums, but maybe I am not hitting the right question. Does anyone know why someone would do this? I don't see where there is any tuner, or how it would function properly with it disconnected. The bike runs fine, has never had an issue. Thanks for the help.

 

If the TP sensor is indeed unplugged the bike would run like crap simply because the engine management system has no idea what actual throttle opening is so fueling and timing is based on base idle settings.
There would also be an engine light illuminating in the speedo since the ECM doesn’t see a good reading for TP.
A pic or 2 showing this condition would be good also since there is at least 1 connector under the tank that doesn’t get plugged in Unless it is an HDI international bike.

Are you sure it's not the active intake connector used on international models? There is no way the bike would run anywhere near ok with the TPS disconnected. Bob refers to it above.

 

Ummm, yeah, you see we're putting the cover sheets on all TPS reports now before they go out. Did you see the memo about this?

Sorry, I had to.

 

Must be an inside joke...im clearly way on the outside

 

Are you sure it's the TPS and not the IAC that's disconnected?
