WARNING: This page is about a different car, the 2024 Kia Carnival. However, it is still accessible from the selected car via links, so may be relevant.

The Electronic Throttle Control (ETC) System consists of a throttle body with an integrated control motor and Throttle Position Sensor (TPS).
The ECM uses the APS signal to calculate the target throttle angle; the position of the throttle is then adjusted by ECM control via the ETC motor.
The TPS signal is used to provide feedback regarding throttle position to the ECM.
