Electric Throttle Control Actuator For California

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 the opening and closing speed of the throttle 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.

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 "Diagnosis Procedure".
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 N, 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 "Diagnosis Procedure".
NO- INSPECTION END


Diagnosis Procedure


1. CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY

1.Turn ignition switch OFF.
2.Remove the intake air duct. Service and Repair.





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, and then perform throttle valve closed position learning. [1][2][3][4][5][6][7]Component Tests and General Diagnostics, "THROTTLE VALVE CLOSED POSITION LEARNING : Special
Repair Requirement".

2. REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR

Replace electric throttle control actuator. Service and Repair.
