THROTTLE VALVE OPENING ANGLE CONTROL
The electronically controlled throttle valve system electronically regulates the throttle valve opening.The engine control unit in the Engine-A/T-ECU monitors the amount of the accelerator pedal travel through the accelerator pedal position sensor and issues premapped target throttle valve opening values to the throttle valve control servo unit in the Engine-A/T-ECU in accordance with operating conditions. Thus, the throttle valve control servo unit achieves the target throttle valve opening by controlling the current supplied to the throttle valve control servo, which is attached to the throttle body. This system also controls the idle speed in addition to controlling the throttle valve opening. Thus, the previously used idle speed control (ISC) motor has been disconnected.
