Throttle Position Sensor: Description and Operation
Throttle Position Sensor (TPS)
The TPS is mounted on the throttle valve body and sends a varying voltage signal to the ECU based on throttle valve position. The ECU can then
adjust fuel delivery based on acceleration, deceleration, full throttle (WOT) or idle. The TPS inputs the ECU through terminal PSW.
