Induction System; Throttle Valve Actuator - SSANGYONG Rexton Y200 Manual

1F1-46 M162 ENGINE CONTROLS
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 deenergized, the throttle valve is resting against
the spring capsule.

INDUCTION SYSTEM

THROTTLE VALVE ACTUATOR

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 according 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;
•
Idle speed control
•
Cruise control
•
Reducing engine torque for ASR/ABS operation
•
Electronic accelerator emergency running
•
Storing faults
•
Data transfer through CAN
