Back order on induction modules removed today. The weird thing is you can't just replace the induction module. They send the new part attached to the input manifold. On my 2010 FLHTCU they are also replacing the wiring harness.

 

Is this happening on the older bikes???
I just did PYO bars and wonder if they worked out these issues for the 2014's.

 

My 2011 FLHTK had this happen once last year and the again today. Bike has about 2500 miles. On both occasions I pulled the main fuse, reinstalled in about 30 seconds and carried on. I'll have to have it looked at...

 

Your bike went into "limp dingus mode".
Happens all the time on bikes from 09 up to and including 2014 models. Do a search, lots of threads on it. No conclusions though.

 

my 2009 throttle failed today for first time with 41k miles. Simply no response to throttle. Open the throttle all the way and stopped at 1800 RPM, I then disconnect the 8 o'clock throttle body plug and started engine with same response unplugged as plugged. I tried to ride to the dealer and made several stops along the way. Eventually after a restart of engine it started working. Rode for an hour home bound with no problem. I did notice the little red key light alarm signal was on the speedo and alternated with the orange engine light on speedo, eventually they both stopped. Now I'm feeling insecure to ride out of town. Looking on here for diagnosis.

 

Pull the plug again and hook it back up. Do this several times to clean the chaffing off of the pins. Then add a little dielectric grease to the pins and ride on.

 

The brilliant techs at my local HD replaced everything from the twistgrip up to and including the throttle body, Still could not figure it out. Untill I told them to check for broken wires inside the insulation between the gas tank and back of the fairing where the factory zip-tie is too tight and wires a bit short. Thanks to an old thread found here. They said don't believe everything you see on the internet. Well I go to pick up bike and lo and behold a crappy looking slice and splice right there! Two years later same problem, So I finnished the job. They had only spliced/extended three of the six wires!
It is hard to notice as the wires break inside the insulation you have to feel for it. But first just try jiggling the pack of wire right near the zip tie your RPM may rev up and/or go back into Limp Mode. That zip tie can be too tight and as time goes by turning bars back and forth wears/breaks the wire inside.

 

Here is a pic of my finnished clean up. Got this heavy nylon sleeve from Goodyear to cover the nasty crooked slice they did on the sheath to get to the wires. Of course I had to do both sides to match. On the left side I found the zip-tie had nearly cut through my antenna co ax cable.

 

I went through this 2 years ago with on 08 EG Classic. It first happened when I was stopped at a gas station, it started and had absolutely no throttle response. I shut if off, started it up and it was fine. A week or two later it happened while riding on the interstate. I pulled over, shut if off and restarted and it worked fine. It happened once more on the interstate and then riding around town some. I researched it some and then brought it down to Smoky Mountain Harley Davidson. The problem is where the throttle by wire inputs go into the throttle body there is a plug with mini pins. On the first models using tbw these pins were made of a material that corroded. The corrosion then prevents the throttle inputs from being sent to the throttle body. HD made the newer models with gold pins which don't corrode. The plug is easy and inexpensive to replace. After SM-HD replaced mine I never had the problem reappear.

 

Thanks! I'm riding to Mexico today for the weekend, spoke with Dealer regarding ECM code P0120 and they would not give me any answers, just wanted to diagnose the bike for discovery but since I reset the code nothing to diagnose. So, we are riding south for the weekend feeling a little in secure. I hope the throttle problem doesn't reoccur. I did clean contacts at throttle body.
