Circuit description: Notes
Idle speed is controlled by the electronic throttle control system.
The electronic throttle control system consists of the throttle motor that drives the throttle valve and the throttle position sensor that detects the throttle valve opening angle.
The engine control computer controls the throttle valve opening angle with the throttle motor so that idle speed is maintained in the target value.
