Testing a Throttle Position Sensor
Right now, there is a bad hesitation when my 2001 BMW R1100S accelerates. I suspect there is a bad spot on my TPS, but I'd still like to verify it with a DMM. I've enclosed a photo of this 4 pin connector to the TPS. There doesn't seem to be a convenient place to insert a T-pin to back-probe the connectors. Does anyone know if there is a pigtail T- connector sold to allow me to easily get to these connectors, when it's connected up to the TPS.
Sorry for the grainy photo.

I am all in when wanting to spend money on the motorcycle.
But, if you want to save a little time and money, just use some fine wire. Just strip the ends of some fine insulated wire , place them in the connector, and then close up the connectors like you normally would. You will find that there will be enough clearance for the wires.

Thanks. I'm definitely not in the mood to be spending money, but my experience has been that the right tool saves me so MUCH time and pain that I'm pound foolish/penny wise to try and scrimp by not having the correct tool for the job.
Having said that, I'll still take your suggestion and gladly give it a try. I have some 22 gauge insulated wire lying around which should hopefully fit. Thanks, Norman |

If you are only checking continuity and resistances w an ohmmeter, use as fine a stranded wire as you have. You don't want to mess up this connector or the mating receptable.

As I stated in my original posting, I'm going to be testing the voltage values to ensure it increases in a continuous way as I roll the throttle.

There are two overlapping pots inside the tps. One for 0-25 degrees and another for 20-90 degrees.
Take care when inserting the fine wires. It is possible (rare) to short to the +5V in the connector and zap your Motronic. |

Playing around with my GS911 on my '03 S, I found that you can use it to set up the throttle position sensor. Mine was well within range.

Twist Ties
Just an FYI. I have used the wire from paper twist ties. Just take some or all of the paper off, cut to desired length.
