Throttle body

TP sensor
Two resistive-track throttle position (TP) sensors are mounted to the single throttle shaft.
•
Both sensors rotate as a unit.
•
Both TP sensors share a common ground circuit, but each sends a separate signal to the PCM based on what
voltage is allowed through each separate resistive TP track.
•
TP sensors are not serviceable individually (both are part of the complete TP sensor unit).
