Can anyone tell me where the throttle position sensor is located on the
87 Tempo. Also is it easy to replace? What function does the Potentiometer serve and would it have any thing to do with erratic ideling and stalling? Thanks, Don
At the end of the throttle shaft in the throttle body opposite the end where the throttle cable and detent cables attach.
Yes, 2 screws although they may be sealed with loc-tite, so heating the heads with a soldering iron/gun may be necessary to avoid breaking the screws off.
It reports to the ECM a value that represents the amount of throttle opening, the rate of throttle change and which direction the throttle is moving (open or closed).
Absolutely, it's the only sensor that can tell the ECM that the throttle has fully closed and that the ECM should apply the proper idle strategy from its programming. But it's not the only cause.
