Wondering about the TPS
Posted October 07, 2002 - 05:43 PM
In the archives, I found a post that reported almost exactly the same meter readings as I got. Has anyone gotten any other TPS readings?
A local mechanic told me that just about every TPS he checks is off enough to affect performance, so I thought I'd check mine. But I don't know how to interpret the results. A new TPS is about $130, so it's not something I'd like to replace if I didn't have to. Thanks.

It bothered me a bit until I checked my '00 and my pal's '01 WR and all were about the same. I did adjust my '01 and I think it idled better afterwards.
I didn't realize they were $130.
Anybody ever had to replace one?

I DID replace mine. I checked the BRAND NEW TPS.
The reading was the same as MY OLD TPS.
I returned it for a refund.
As I recall, the readings did NOT match the manual.

My TPS coil resistance was 4.75k and the book calls for 4-6k, so that looked good.
My TPS variable resitance closed is 1.26k and the book called for 0-2k, so that also looked good.
This is for the 02 model.

There should be a dab of green paint across the TPS and carb body so you can return it to factory position, but I just wanted to see if there was any discerible change to be had. I can't remember which direction, but if you "fool" the CDI into thinking the throttle is more open than it actually is and turn the unit all the way in this direction, in my case anyway, it did not want to idle at all. A slight adjustment over stock in the OTHER direction seemed to give it a smoother idle. I didn't notice any ill effects otherwise so I left it there and haven't gone anywhere near my bike with an ohm meter since.
I know the ignition timing is affected by the TPS readings, and assumed it was a continous type of change, but it could be stepped or something, in which case I probably just imagined my idle improving. Not sure...
