Throttle position sensor

I'm having a hard time finding a source for throttle position sensors. I have looked at Ebay and through the Ducati Micro diagrams and found nothing. Can you point me to a source on where to get them please?

The TPS is part of the throttle assembly, why would you need to replace it?

Inconsistent voltage coming from the sensors. Apparently it's a common issue with all Ducati 's. This is said to be what is causing my sputtering and surging while maintaining a steady throttle. I have gone through so much with this bike and this is just about the only thing left. I have read numerous links and posts that point to the TPS, only a few were for the hyper though. New plugs, new eldor coils, new lithium battery, rewire the wiring harness, clean all contact points to every connector, clean O2 sensors(thought #2 was bad but switched it with #1 and the #2 still says it's too rich), verified that the drive by wire throttle tube is operating properly, plus a few other things. Many of the posts I have read, the TPS is something that has a tenancy to wear out and cause my exact issue. Some of the posts said that it happens after having the dealer sync/reset the TPS. I recently had that done and have been having issues ever since.

Damn, those don't sound cheap. Think cleaning the contacts would help. We are having the exact same issue so I'm following your lead.

The service bulletin was supposedly covered back in 2016 according to the 2 dealers in Michigan(I called them both because I didnt believe them). They replaced the throttle for that bulletin.

I think you'll find euro 4 emissions is to blame for the spluttering during steady throttle.
Fit a rapid bike evo module and you'll find its so much better.

I have a rapidbike module and the rapidbike technicians went in 2 times remotely to try and resolve my issue and it did not fix the problem which is why I have been digging into it deeper.

Ok, I have the rapid bike and had a similar problem with a steady throttle. Turned out to be a bad connection on the lambda sensor which later failed.
I replaced the lambda sensor and bike has been fine since.
