Throttle position sensor question

[slash]

Is it ok to take the tps off a bike and put it back on with out affecting it.  The reason I'm asking is that I took the tps off my gf bike to see if it would fix a problem I'm having with my bike. (It didn't).  I immediately put it back on her bike and the bike started fine.  Did I do something really bad?  Is her bike going to need the tps readjusted?

You likely changed the position of it. You will probably need a multimeter to make sure it is adjusted properly...

Which 2 bikes did you swap TPS sensors on?

I took the tps off an S2R and it put on an S2R1000 (they have the same part number).  Then I put it back on the S2R...will it need readjusting?

It should be reset, just in case, though it is probably OK.  Since there is some play around the srews it may be off a little.

The TPS is so sensitive to movement it will need adjusting , 150-152mv is fine with throttle bodies fully closed :eg idle screw fully wound out.
you will also need to balance the throttle bodies with a vacuum gage.

It depends what year the bikes are, there are linear and non-linear TPS.

One gets set manually with a mV reading (or with a diagnostic device that gives degrees) and the other is set only electronically.

If the TPS has round screw holes instead of long arc shaped ones they are linear TPSs, which I think is the case.  They may have moved a little but are probably OK.  If the bike runs fine don't worry about it until the next major service when it will get reset anyway.  If the bike won't idle or runs poorly when cold, etc, you need to get it readjusted and need a computer to do it. 

If they are the non-linear TPS (arc shaped mounting holes) you most surely need to readjust them but you can do it easily with a volt meter.

Now comes the real question .... Does she know you "borrowed" her TPS?

as stated ride he bike if it is too lean you will know soon. if it is too rich it will be lazy on the throttle.
With your TPS it will need resetting with the software. next time you stop in BCM have them plug in and re-set it. it will only take a second.

Ducvet, thanks for the advice...i'm truckin' both bike to NH tomorrow...do you know a good marriage counsellor?

you dont need a computer to set the TPS just a good multimeter, but its not an easy job to set .

Linear TPS must be set with diagonsic software.  The switch does not adjust, the computer needs to learn throttle position.

when u say compouter do you mean only Mathesis or also VDST units also.

I was referring to the ECU, The Mathesis. DDS (replaces Mathesis) or VDST is needed to do the task.
