P2119 ELECTRIC THROTTLE CONTROL ACTUATOR

Description

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 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.

DTC CONFIRMATION PROCEDURE


1. PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.
- GO TO 2.

2. PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A AND B

1.Turn ignition switch ON and wait at least 1 second.
2.Set selector lever to D (CVT) or 1st (M/T) position and wait at least 3 seconds.
3.Set selector lever to P (CVT) or Neutral (M/T) position.
4.Turn ignition switch OFF and wait at least 10 seconds.
5.Turn ignition switch ON and wait at least 1 second.
6.Set selector lever to D (CVT) or 1st (M/T) position and wait at least 3 seconds.
7.Set selector lever to P (CVT) or Neutral (M/T) position.
8.Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
9.Check DTC.
Is DTC detected?
YES- Go to .
NO- GO TO 3.

3. PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION C

1.Turn ignition switch ON and wait at least 1 second.
2.Set selector lever to D (CVT) or 1st (M/T) position and wait at least 3 seconds.
3.Set selector lever to P (CVT) or Neutral (M/T) position.
4.Start engine and let it idle for 3 seconds.
5.Check DTC.
Is DTC detected?
YES- Go to .
NO- INSPECTION END


Diagnosis Procedure


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.
-Electric throttle control actuator (2)
Is the inspection result normal?
YES- GO TO 2.
NO- Remove the foreign matter and clean the electric throttle control actuator inside, then perform throttle valve closed position learning. Refer to "THROTTLE VALVE CLOSED POSITION LEARNING : Special Repair Requirement".

2. REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR

Replace electric throttle control actuator. Exploded View.
