Throttle Positioning Sensor reset.

[dihoward]

I recently put a power plug on a 2009 R1200GS. The bike still dies rolling to a stop. Will the GS911 reset the TPS ?

suggestions welcome.

I have a 2003 K1200 GT, to reset the TPS I turn the key to on, kill switch on, rotate the throttle fully three times and return it to rest. Turn the key off. The TPS is now reset. No need for the GS 911.

I think you will find the TPS constantly recalibrates and the twist throttle 3 times applied to very old models

Sounds like the OP has an issue with stalling. A TPS might help solve that, a GS911 is not needed  for that. It could be the idle bypass controllers being out of synch, a GS911 can reset those.
It could be one or more of a few  other things. In no particular  order:
A coil breaking down.
A trapped  throttle cable.
Bad spark plug (s).
Someone  adjusting the factor set throttle  stops.
Valve clearances way out.
I would go the easy one of checking the cables, especially  the rightbhadone Then do the standard TPS reset procedure; check the valve clearances and if you have GS911 reset the idle bypass adaptation.

Please elaborate on the idle bypass adaptation. What is the function?

Correct.  TPS is reset each time you cycle the ignition.

The idle bypass controllers  Are the electrical  devices on your throttle  bodies on the top side nearer the engine. They have some form of sensor built-in  to indicate their exact positioning. The ECU says "go to position X" so they need to know where zero is, and when they are exactly  at position X. Sometimes  they lose track of zero and so where they are. Resetting  their adaptation is a function on the gs911 that sends the controllers through a few routines to relearn their zero positions and their full range.

The stalling  could also be caused by a failing lambda sensor.
I have found that a failing sensor may not throw an actual fault. The real-time output values may  be constantly  on the rich or weak side of stoic as the sensor is starting to fail. It can take long time before it actually stops working.
