WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
Throttle Position (TP) sensor uses a 5-volt input voltage supplied by PCM. PCM uses TP sensor reference signal to determine throttle position for controlling shift points, shift quality and torque converter clutch lock-up.
