I had high idle and replaced my TPS, IAC and MAF. The idle then was good, BUT the transmission shifted up way to early and lock up in low speed and low rpm. I should take of the cable to the TPS to measure it, then the TPS fall apart, and what a simple construction.
I then put back my old TPS and now the shifting is more normal, but the idle is high (1250 rpm).
Is it correct that a bad TPS behave like this?
Is my old TPS is still bad since the idle is high or is it a combination with a bad IAC (the IAC is new, but also from STANDARD)
Someone that have a website that has GOOD sensors?
The sensors i got is in a red box called STANDARD, should i change the IAC and MAF too since they are from the same company??

 

Will this two function okey?

My OLD TPS is now in the car, the transmission shifting is normal, but the idle rpm is high. I used a volt meter and the volt out from the TPS is 2 VOLTS when its closed, thats way to high, correct? the readings are from 2 at close to 4,85 at full open , its not any drops or something on the way its smooth from 2 to 4,85.

My NEW TPS that made the transmission shift to early mesasure 0,5 - 4,85 volts from close to full open, not any drops or anything.


Q1:
Why is my new TPS shifting to early, shouldnt it be the bad TPS that should do that since it tells that the throttle is more open than it is?

Q2:
Should the idle rpm be higher when the throttle is closed but the TPS tells that is a litle open?

Q3:
Is the IAC adjusted with information from the TPS and therfore the rpm is higher than it should be since the PCM is thinking that the engine isnt in idle and isnt using the IAC in any way?

Q4:
Is the IAC open or closed when the PCM gets info that the enginge isnt in idle, it must be open beacuse if it was closed shouldnt the engine stops without any air?

Last question.
IS Omix-ada or Delphi good parts.
