Throttle Position Sensor
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2003 Dodge Grand Caravan, 2003 Dodge Caravan, 2003 Chrysler Voyager, 2003 Chrysler Town & Country, and 2002 Dodge Grand Caravan. However, it is still accessible from the selected car via links, so may be relevant.
On all models, Throttle Position (TP) sensor is nonadjustable. DO NOT attempt to adjust TP sensor by rotating. Output voltage (center terminal of TP sensor) should be approximately .8 volt at closed throttle (idle) and more than 3.5 volts at Wide Open Throttle (WOT). Voltage should increase gradually and smoothly as throttle is slowly opened from idle to WOT. TP sensor must be replaced if it is out of range. For diagnosing TP sensor circuits, see appropriate SELF-DIAGNOSTICS article.
