P2118 THROTTLE CONTROL MOTOR
Description INFOID:0000000004780309
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The current opening angle of the throttle valve is detected by the throttle position sensor and it provides feed-
back to the ECM. ECM controls the throttle valve opening angle in response to driving conditions via the throt-
tle control motor.

P2119 ELECTRIC THROTTLE CONTROL ACTUATOR
Description INFOID:0000000004780314
Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc.
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The throttle position sensor detects the throttle valv e position, and feeds the voltage signal to the ECM. The
ECM judges the current opening angle of the throttle valve and controls the throttle valve opening angle in
response to driving conditions via the throttle control motor.

P2122, P2123 APP SENSOR
Description INFOID:0000000004780318
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 potentiometer which transform the accelerator pedal
position into output voltage, and emit the voltage signal 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 accelerato r pedal is determined by the ECM
receiving the signal from the acce lerator pedal position sensor. The
ECM uses this signal for the engine operation such as fuel cut.
