I've got a strange one.
After changing the clutch last weekend (97 R1100GS). I've just been checking the bike over to make sure it all went back together OK. I thought I'd check the TPS voltage, but I couldn't get a reading. So I checked the TPS itself , all OK there (moves from 1043 to 1732 ohms as you open the throttle). I don't seem to be getting much voltage on pin 1 of the TPS wiring (maybe 6 milivolts?), pin 4 seemed to have a good earth. I checked the fault codes and got 1133, 1122 (hall sensors - expected given engine wasn't running) and fault code 1111 (CO pot). No TPS fault, I then cleared the faults down and checked again, same fault codes were back. I checked pin 2 of the CO pot wiring and there is 2.5 volts there.
Anyone know what voltage I should expect at pin 1 of the TPS?
I'm thinking this might be a problem with the big TPS connector? Maybe I disturbed something when I took the bike apart?
The bike starts and idles OK though
Or has the motronic started to pack up?
