Electronic Throttle Actuator: Description and Operation
Electronic Throttle Control System
The throttle is electronically controlled by the electronic throttle control system. Refer to the System Diagram to see a functional layout of the system.
Idle control: When the engine is idling, the ECM/PCM controls the throttle actuator to maintain the proper idle speed according to engine loads.
Acceleration control: When the accelerator pedal is pressed, the ECM/PCM opens the throttle valve depending on the accelerator pedal position (APP)
sensor signal.
Cruise control: The ECM/PCM controls the throttle actuator to maintain set speed when the cruise control is operating. The throttle actuator takes the
place of the cruise control actuator.
