The throttle position (TP) sensor is used by the powertrain control module
(PCM) to determine the throttle plate angle for various engine management
systems. The TP sensor is a potentiometer type sensor with 3 circuits.
The PCM provides the TP sensor with a 5-volt reference circuit and a low
reference circuit. Rotation of the TP sensor rotor from the closed throttle
position to the wide open throttle (WOT) position provides the PCM with a
signal voltage from less than 1.0 volt to greater than 4.0 volts through the
TP sensor signal circuit. If the PCM detects an excessively low signal
voltage, this diagnostic trouble code (DTC) will set.
