INDUCTION SYSTEM
THROTTLE VALVE ACTUATOR
YAA1F540
The throttle actuator is actuated by the Engine Control Module (ECM) according to the position of the accelerator pedal
position.
It has two potentiometers which signal the position of the throttle valve to the ECM to enable it to recognize the various
engine load states.
Ignition “Off”
In the de-- energized states the throttle valve position is determined to be spring capsule.
Ignition “On”
When the ignition S/W on the servo motor in the throttle actuator is operated by the ECM. The throttle valve adopts a
position in line with the coolant temperature.
Closed position
In the closed throttle position, the servo motor controls engine speed by operating the throttle valve further (greater
mixture) or closing it further (reduced mixture), depending on coolant temperature and engine load. When this is done,
the throttle valve can be closed further by the servo motor overcoming the force of the spring capsule (mechanical end
stop). If the actuator is de-- energized, the throttle valve is resting against the spring capsule.
Consequently, the throttle valve opening is a constant 10-- 12°approximately.
At no load, this produces an engine speed of about 1,800 rpm
Driving
When driving (part/full throttle), the servo motor controls the throttle valve in line with the various load states and ac-
cording to the input signals from the pedal value sensor according to the input signals from the pedal value sensor
according to the position of the accelerator pedal.
The function of the EA (electronic accelerator) in the ECM determines the opening angle of the throttle valve through
the throttle actuator. Further functions are;
DIdle speed control
DCruise control
DReducing engine torque for ASR/ABS operation
DElectronic accelerator emergency running
DStoring faults
DData transfer through CAN

Circuit Description
Cruise control is an automatic speed control system that maintain a desired driving speed without using the accelerator
pedal. The vehicle speed must be greater than 40 km/h to engage cruise control.
