Kia Sportage: Engine Control System / ETC (Electronic Throttle Control) System Description and operation
The Electronic Throttle Control (ETC) System consists of a throttle body with
an integrated control motor and throttle position sensor (TPS). Instead of the
traditional throttle cable, an Accelerator Position Sensor (APS) is used to
receive driver input. The ECM uses the APS signal to calculate the target throttle
angle; the position of the throttle is then adjusted via ECM control of the
ETC motor. The TPS signal is used to provide feedback regarding throttle position
to the ECM. Using ETC, precise control over throttle position is possible; the
need for external cruise control modules/cables is eliminated.
