Question lost Throttle control

I was on a weekend ride to and from Gatlinburg Tenn to Gainesville Ga. and I had a problem with my throttle not responding. I shut the bike off and it went away but on the way home the check eng light came on. It ran fine the rest of the trip. Today i went to start the bike (2014 Ultra Classic) the check eng light is on and i have no throttle responce at all. The Cruse control light is blinking also.
Any suggestions.

Had similar problem, throttle would not respond but would idle. It was the harness going to the throttle body, had moisture in it. Replaced wiring harness to throttle body and was fine.

I have not gotten the bike wet in almost 2 weeks and it was fine all the way up to Tenn.

Had the same problem after doing bars on my 2012 road glide. Cut the green connector on the throttle wire and eliminate it. Solder the wires back together and you will be good to go. The pins inside lose contact causing it to go into limp mode.

How do I clear out the codes after I get the wire fixed?

Copied this from another forum. Hope it helps.


The IM (instrument module) is capable of displaying DTC's (diagnostic trouble codes).
Speedometer Self Diagnostics: The speedometer is capable of displaying and clearing speedometer, tachometer, TSM/TSSM and ICM/ECM Diagnostic Trouble Codes (DTC).

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.

2- Push odometer reset button in & hold.

3- Turn ignition switch to Ignition and release odometer reset button. Background lighting sould illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word “diag” should then appear.

4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.

5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted])
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer

6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC’s the code will be displayed or the word “none” will appear if there are no DTC’s. Push the odometer reset button again to view additional codes if they exist.

7 - Record the codes.

8 - If DTC’s are not to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC’s again by repeating steps 1 to 9. If the code is current it will reappear.

9 – Press and release the odometer reset button to continue to the next module.

10 – Turn Ignition switch to OFF.

Any suggestions.
Use some electrical gel on the plug contacts like the stuff that is on your light bulbs.
