Hey Primers, I'm looking for some help or suggestions with this issue I am having. I have some information in the this thread here, but my question is more specific to my problem. For reference the car is a 97 NSX-T, 6spd - it is a drive by wire car.
I installed a new throttle position sensor today and I'm having problems getting into the recommended specs for voltage. For reference - specs call for .45v throttle closed and 4.5v full throttle. My original TPS measured .39v closed and 4.1 open. After installing the new one I can only get one of the numbers in spec. If I adjust the closed voltage to .45v the best I can do on the full throttle voltage is 4.23v. If I adjust the full throttle to 4.5v then the closed voltage is .8-.9v. I have looked at the plate position in either case and it is closed (small gap) and fully open (I can't move the plate to anymore open). I opted to go with putting the closed value in spec. The throttle response feels much better and it appears to be easier to drive in stop and go situations, but since I reset the ECU I think I have to wait until the idle is back to normal before a final judgement (on reset it seems to start at 1100rpm and eventually get down to 900rpm).
I should also mention that I verified that the accelerator pedal sensor at the front of the car was also in the correct position (couldn't turn anymore at WOT).
Should I be worried that the WOT voltage is out of spec? The howto on the site only seems to worry about the closed voltage - in install document that came with the TPS it says to make sure both are in spec.
If I should be worried, any suggestions on how to fix the issue?
Thanks,
Edward
