So I just bought my first bike a month ago. Its an 03 CBR600rr. The bike works great most of the time, but once in awhile the bike will bog down and won't let you rev up past 3k.

Took it to the shop and it brought up 2 codes:
1st code was saying the battery was bad.
2nd code said there was insufficient voltage to the TPS sensor.

So we replaced the battery thinking it would fix both codes. Rode away thinking it was fixed but throttle still cut out on me. I was told I may have to replace the whole throttle body to fix the TPS sensor issue. Does this sound right? Or could there be an easier fix? Any help would be much appreciated.

Possibly the TPS could be replaced but I don't think you'll find just the TPS. If someone wiped out bad enough to damage the throttle bodies... I doubt that they'd pull off the TPS and junk the rest. But search... you might find what you need.

Can anyone thing of any other potential fixes before I replace the whole throttle body? Id hate to do all that work and that not even fix it.

The manual describes a way to check the TPS voltages. Something worth doing just to make sure the TPS is bad instead of the ECU or maybe a wiring problem.

I don't know it from memory but anyone with the manual can look it up.

I am very frustrated at this point. I swapped out the throttle body and I'm still having the same issues. Any ideas of what to try next? Trying another ECU was my only other thought. Maybe change out the wiring but that would be a big project. Any help would be much appreciated. Thanks.
