Hi all
I have a 2012 S1000RR that was randomly going into limp mode (engine on, but no throttle). Happened twice on track, which is of course not ideal.
Plugged in and saw that the TPS sensors were throwing errors - so took the plunge and bought 2 new sensors from BMW and replaced the throttle position sensor and the twist grip position sensor. Note, I also have a PC5 installed
Plugged everything back in, went to fire it up but it failed.
2 things to note:
1) Fuel pump not priming when turning on ignition
2) Throttle not registering any voltage movement when PC5 connected to laptop

So, questions are:
1) Are the TPS sensors coded, and do I need to get proper BMW diagnostic tools to initiate the new sensors?
2) Any idea why the fuel pump would not prime?

Especially bypass the PC5 until you have it running again. GS911 needed for adaptations.

Reset twist grip sensor to teach that in. Check fuses and kill switch as to why fuel pump won't prime. I'd also disconnect PC5 and troubleshoot stock.

Thanks. Is there a manual way to reset twist grip, or do I need to plug in to GS-911?
