COMPONENT PARTS
ECM
INFOID:0000000010986201
The ECM consists of a microcomputer and connectors for signal
input and output and for power supply. The ECM controls the engine.
Accelerator Pedal Position Sensor
INFOID:0000000010986202
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the accelera-
tor position and sends a signal to the ECM.
Accelerator pedal position sensor has two sensors. These sensors
are a kind of potentiometers which transform the accelerator pedal
position into output voltage, and emit the voltage signal to the ECM.
In addition, these sensors detect the opening and closing speed of
the accelerator pedal and feed the voltage signals to the ECM. The
ECM judges the current opening angle of the accelerator pedal from
these signals and controls the throttle control motor based on these
signals.
Idle position of the accelerator pedal is determined by the ECM
receiving the signal from the accelerator pedal position sensor. The
ECM uses this signal for the engine operation such as fuel cut.
Electric Throttle Control Actuator
INFOID:0000000010986203
Electric throttle control actuator consists of throttle body, throttle valve, throttle control motor and throttle posi-
tion sensor.
