I went back down and started over. Making sure i had the sensor positioned correctly, measured voltage at yellow wire with key on and only could get up to .66 at idle and 2.12 at w.o.t (not running). I then moved the meter to the 20vdc setting instead of 9v and what a difference in readings. I was able to set sensor at.73 and w.o.t. at 3.55. Test ran and idle jumped to .75 so i backed sensor down to .73 while running at idle. I did not turn the "d" shaped idle screw as it idled and ran fine before I removed tps sensor. Looks like my problem was the wrong setting on the meter. oops.

 

Sorry I didn't see this before. I could've saved you a little trouble. I knew about the 20vdc setting. I forget who makes it, but someone has a small "kit" for TPS settings that uses a cheap multi meter and a test harness. While looking at it, I was able to pull up the directions, and it said to use the 20vdc setting. So I figured it should work like that on almost every meter. Tried it on mine, and it did, lol.

Something else I noticed was the different values between a bench test and a mounted test. My readings on the bench using a 9v battery were considerably different than readings while it was installed on the machine. I ended up having to set the TPS while installed in order to get the correct readings to make it run right.

 

Does it idle any faster or slower or smoother when doing this?

 

I'm not exactly sure what your asking me. I don't know what it was idling at before I removed it but now it is right around 1300 and pretty smooth I guess. When I was adjusting the sensor while it was running, I was barely moving it(from .76 to.73) so there wasn't much difference in the idle. I hope this helps.

 

You did. For some reason ,I thought lower voltage told the ecm slower idle speed. Thanks.

 

You will get an inaccurate reading if you use the vehicle frame as ground. You need to use the two wire off the TPS. I think it is Blk which is ground and Yellow which is the output of the TPS. I have found that if you turn the key on without starting the engine that the TPS voltage will be .02 lower than with the engine running. It's easier to set with the engine not running. .735 is the correct voltage.

Correct.

 

Thanks for the advice. I used the battery ground at the engine. I'll try the paper clip method to retest as i've already covered up my test location on the yellow wire. I guess the only other question is should I set it at .735 with key on and leave it alone or should I set it with the machine running at .735?
