Has anyone else experienced this problem and if so how was it resolved. I have a 09 Ultra now with 16004 miles on it. Last year while riding around my home area the throttle quit responding, the engine light came on and the bike went into an idle. No response at all from the throttle. At this time the bike had 7900 miles. When the bike sat for about a half hour I started it back up and the throttle was working again, tried to make it to the dealer as I pulled into the driveway it went out again so it was easy to show the trouble to the service guys. Well they called MOCO and they first had them swap the ECM that did not fix the problem then they swapped the induction module, this worked. Now a year later and double the miles on my way home from Maine it happens again. Can this induction module go bad again; this could get costly if I didn’t have a warranty still. The Bike is at Erie H-D and I am at home in Michigan.
By the way Erie H-D owner and employees are the greatest. They bent over backwards to help me. They didn’t know me at all and they came and picked me up on the freeway and help me get back on the road home. I recommend them if you ever need anything.

 

I'm at a loss to understand why you had no comments about this, but anyway-- this time check the ECM connection pins for corrosion where the pins are visible.
Others have commented that throttle issues were found to be related to corrosion.

Or, yes, the induction module could fail again I suppose, but I haven't read/heard of this failure before now.

I had the dreaded "check engine" light and no throttle at 500 miles on my 09 UC. Allegedly, (as informed by the dealer who did the repair) the dealer that installed the Stage 1 AC ran a wire too close to the head and burned/shorted it to ground....

 

Thank you for your input, My guess is that this is has not been a problem with the TBW with most riders.

 

You could use the search function to investigate. I know there is more about it here than what we've discussed.

Good luck!

 

Man that sux.

I'll take my antiquated cables anyday. But then, I had a clutch cable snap on an old metric bike I had. That made for an interesting ride home.

 

personally, I like the cables. It's easier to diagnose and less money to fix. I just like simple. Getting old I guess.

Kroozeabout.

 

I haven't had issues with my TBW yet (knock on wood-- TAP TAP). But I have changed my handle bars, and I've seen the parts in there. And although I have had no issues to date, I was kind of surprised.

If you've seen the throttle sending unit in the handle bar, you know why I was surprised (and I know of a few folks who have had problems with them failing).

It must be voo doo magic how they can take five dollars worth of material and turn it into an eighty something dollar part (last I heard). It looks that cheap.

It's the same design as an old two wire radio volume **** (reostat). The only difference is it has a spring to return it to zero/off. It works great (so far). But I would have thought it would be more robust for this application.

 

dshukwit,
Did you have 'any' throttle response at all? Maybe just a little, up to say 2000 rpm?

If so, you may have a broken wire in the TBW connector underneath the Air Cleaner. Very difficult to troubleshoot, but it happened to me over Memorial Day weekend, and I ended up having to spend an extra day (5/31) on my road-trip awaiting Durango H-D to open up so they could fix the scoot.

After a number of checks and investigation, the tech did find the broken wire and made the repair.

The tech did tell me that the MoCo did build in a fail-safe, so that if the TBW does encounter a situation like that, you will have enough throttle to get you to a safe location.

Good luck!

 

KoalaCowboy,
I had no throttle, engine light came on and bike went into an idle. after 30 minutes or so I started it back up and the throttle worked again. Dealer is still testing trying to duplicate the problem.

 

this happened to me this spring in heavy traffic
almost caused an accident
for me they replaced the dbw grip sensor with a new
part number, they told me it was a common problem
until this time no more problem
