the car has had some funky WOT hesitation for a while, resetting the ECU always seemed to solve it for a few days, but today, it got a WHOLE lot worse... driving down the road, anything over about 60% on the s-afc resulted in the engine stalling until i let off the gas.

I just drove it home from work now, and it seems fine, but I'm sure this'll crop up again.

anyways, my first guess is the TPS has died.. this sound right?

 

Sounds about right. A dead spot in the TPS will cause this...

 

Hook up a meter to that bad boy at the ECU and go for a drive. Or just turn the key on and slowly push the throttle while watching the meter...If she's bad, you'll see it...

At WOT, though, the TPS output has already been maxed out for a while...

 

Anything over 60% on the S-AFC...Which should be around 15% of max throttle or so...

 

How can the TPS go bad? Recently Ive replaced my whole harness and let the car sit in my garage for two months, with the UIM off. Finally put everything back together and, idle hasnt been the same.

Tried to adjust the TPS using the directions on FC3SPRO and I think I just made it worse... It says to set the TPS to 1OHM but the closest I can get it 1 is 1.4ish.

Is my TPS fucked?????

 

Bump

 

It's actually 1000 Ohms or 1K Ohms.

Im assuming that you warmed up the car prior to checking and setting the TPS.

A good way to see if your TPS is FU'ed, connect the DMM and set the TPS to 1K Ohm. Once you've done that, open the throttle all the way (WOT). If you get a reading greater than 6K Ohms, then your TPS is going or gone.

Hope that helped.

 

That is exactly what I did. The thing is, my TPS wont set to exactly 1 OHM. Also, when I go WOT, it doesnt go to 6 OHM, the highest is 5.2OHM warm or cold. So I dunno... Shiet! When adusting it, do you go counter clockwise or opposite? Please help.
