Throttle Position (TP) Sensor
WARNING: This page is about a different car, the 1995 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
Output voltage (center terminal of TP sensor) should be more than .20 volt at closed throttle (idle) and less than 4.8 volts at WOT. Voltage should increase gradually as throttle is slowly opened from idle to WOT. TP sensor is not adjustable.
