Just kinda curious. I put my TPS on the other day and kinda just dialed it in by sound and reaction. What is the proper way? Is it possible I am robbing my HP/TQ? Just a thought that crossed my mind yesterday while playing.
I ran into a problem with my TPS being out of adjustment last week during a dune trip. Starting running like shit. The proper voltage should be between .63v - .73v. Adjust the angle of the TPS until the voltage is within those limits.
Positive tester probe - yellow wire
Negative tester probe - black/blue wire
Checked plug, it's white.... means she's running lean. How do I exactly check the voltage?
With the key on, engine off, connect the yellow wire to the positive tester probe and the black/blue wire to the negative tester probe. It should read between .63v and .73v. If it's outside of this range, loosen the two torx bolts and adjust the angle of the TPS until the voltage is within those limits.
Ha, just checked it. It was reading 1.03v. Changed it to .67v. I noticed a difference right off the batt. It started immediately as I pushed in the start button. It usually just winds until I give it some gas to help start it.

Thanks Wobble, but I got impatient and ran out there and took a look at it before you posted, yeah its not exactly brain science I guess. lol. Anyhow thanks for the heads up. :thumbs: I was hoping that was some of the problem.
Sweet! Hopefully it helps. My rappy really ran like crap with my TPS out of spec. Sometimes it ran fine, other times not so good. Might want to check it after a couple rides though. Just to make sure the TPS isn't failing on ya. That's what I'm gonna do when I get my RE head back next week and get it back together.
Here's the way through the PCIII software.. just for reference for my self. to print the topic
use a NEW 9v battery with the adaptor.... key and ignition on.... throttle closed CLICK left arrow, throttle at WOT click right arrow, then u are good to go!
Just to clarify....you set the voltage on the TPS first.....then go into the Power Commander software and set the throttle position values, resetting the values has no effect on the TPS voltage. However anytime you physically move the Throttle Position Sensor and adj the voltage, then you need to check/reset the TP values in the Power Commander software as they can be affected by changing the voltage or moving the TP sensor . Kinda like on an old school points ign. system adjusting dwell changes timing, but timing doesn't change dwell.
Also any time you change maps you should check/set the TP values in the PC software.

Dualy Noted. Thank you sir. :thumbs:
Were are the wires at? I have tree black wires on my tps 1 2 3 port numbers? Also what is idle to be set at?
So, even though you reset the throttle position values using the PC3 software, you still need to check the TPS voltage with a volt meter? I didn't do this because my friend told me that you didn't have to with a PC3.... Does this only affect starting?

I need help. I'm dumb... I've never used one of these things. Here's a pic of the one I have below (just picked it up) I have no idea what setting to put it onto or anything.... :help:
Also. Since I have the pc3 plugged into the TPS. all of the wires are black. Does anyone know which wires are the black/blue and the yellow? I'm pretty sure the middle wire is the yellow, since coming off my dynatek was a yellow wire to that one. but just want to make sure.
I did the PC3 TPS reset this weekend, my values were waaaaaay messed up. the first value was about 3000 higher than what it was when I reset. and the end (high value) was almost twice as high as it should have been. :help:
RTFM :rofl: :rofl: :rofl: :rofl:
but no seriously read the manual, I'd assume alot of meters are different.
I can't tell for sure because of the out of focus picture, But It looks like you turn the knob one click to the right where it says 10 on the DC volt scale. Then reading the scale it will be the black line with black numbers that start what looks like it might be 2 then 4, 6, 8 and 10. You will want the pointer to point some where on 3 or 4 lines above the zero volts. Each line equals 2 tenths of a volt on that 10 volt scale. That meter does not have the resolution to read exactly .63 or the .73 volts but it could get you close. I would recommend a digital multimeter if you ever but another one they are much easer to read and usually have a better resolution. And you don't have to calibrate it like you do for the analog meters:thumbs:
I tried reading the manual was freakin japanese to me. All I want to know how to do is this. that's all I forcee using this multi-meter for.
but. with the PCIII plugged in. do you guys know which wires it is between top mid and bottom? I suppose I can look it up in the manual to see which are which for the stock plug on the TPS.
Krandall this will be hard to do with an analog meter. Does your analog meter go down to a 2 volt setting? ??? What is the lowest setting? Also you asked which wires are which. I did this last weekend so, sitting on the right side of the raptor looking at the connector, the middle is the positive and the top wire is the negative. If you have any more questions just hollar.
dang. No, from 1-10 its by 2. :(
Back to menards I go.
can you check it through the factory plug if its disconnected? If you can and it is an accurate reading mine is reading 4.27 on a digital meter. also what size are those torques bits to move the tps. im thinking a t-26
did you end up fig this out randy?
I found out my multimeter doens't go down to the level of reading I need :(
So I went ahead and adjusted through the PC App only. Runs like a beauty. :thumbs:
Your TPS must be in spec then :thumbs:
that's what I'm guessing, but for peace of mind I'd like to test it still :)
finally got a test on mine.it read 70.0 :thumbs: so i guess its good

If it ain't broke.....don't fix it ;) :)
