P2119 ELECTRIC THROTTLE CONTROL ACTUATOR

Description

INFOID:0000000004211613

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 valve position, and the opening and closing speed of the throt-

tle valve and feeds the voltage signals to the ECM. The ECM judges the current opening angle of the throttle

valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening

angle properly in response to driving condition.

2. Set shift lever to D position and wait at least 3 seconds.

3. Set shift lever to P position.

4. Turn ignition switch ON (READY).

5. Depress the accelerator pedal to start engine, then keep engine running for at least 3 seconds.

6. Check DTC.
Is DTC detected?

YES

>> Go to 

EC-366, "Diagnosis Procedure"

.

NO

>> INSPECTION END

DTC No.

P2119 ELECTRIC THROTTLE CONTROL ACTUATOR

Diagnosis Procedure

INFOID:0000000004363299

1.

CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY

1. Turn ignition switch OFF.

2. Remove the intake air duct.

3. Check if foreign matter is caught between the throttle valve (1)

and the housing.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Remove the foreign matter and clean the electric throttle

control actuator inside.

2.

REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR

1. Replace electric throttle control actuator.

2. Go to 

EC-15, "THROTTLE VALVE CLOSED POSITION LEARNING : Special Repair Requirement"

.

>> INSPECTION END

Special Repair Requirement

>> GO TO 2.

2.

PERFORM IDLE AIR VOLUME LEARNING

Refer to 

EC-16, "IDLE AIR VOLUME LEARNING : Special Repair Requirement"

>> END

P2135 TP SENSOR

Description

INFOID:0000000004362826

Electric throttle control actuator consists of throttle control motor,

throttle position sensor, etc. The throttle position sensor responds to

the throttle valve movement. 

The throttle position sensor has two sensors. These sensors are a

kind of potentiometers which transform the throttle valve position into

output voltage, and emit the voltage signal to the ECM. In addition,

these sensors detect the opening and closing speed of the throttle

valve and feed the voltage signals to the ECM. The ECM judges the

current opening angle of the throttle valve from these signals and the

ECM controls the throttle control motor to make the throttle valve

opening angle properly in response to driving condition.
