| Description |
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.
