P2118 THROTTLE CONTROL MOTOR
P2118 THROTTLE CONTROL MOTOR
DescriptionINFOID:0000000005930073
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 openi ng angle in response to driving conditions via the throt-
tle control motor.

P2119 ELECTRIC THROTTLE CONTROL ACTUATOR
P2119 ELECTRIC THROTTLE CONTROL ACTUATOR
DescriptionINFOID:0000000005930079
Electric throttle control actuator consists of th
rottle 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.
