P2119 Electric Throttle Control Actuator

Component 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 sends the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and opens/closes the throttle valve in response to driving conditions via the throttle control motor.

On Board Diagnosis Logic

This self-diagnosis has the one trip detection logic.





Fail-Safe Mode

When the malfunction is detected, the ECM enters fail-safe mode and the MIL illuminates.






DTC Confirmation Procedure

NOTE:

- Perform PROCEDURE FOR MALFUNCTION A AND B first. If the DTC cannot be confirmed, perform PROCEDURE FOR MALFUNCTION C.
- If DTC Confirmation Procedure has been previously conducted, always perform the following before conducting the next step.

1 Turn ignition switch OFF and wait at least 10 seconds.
2 Turn ignition switch ON.
3 Turn ignition switch OFF and wait at least 10 seconds.

Procedure for Malfunction A and B

1) Turn ignition switch ON and wait at least 1 second.
2) Shift selector lever to D position (A/T) or 1st position (M/T), and wait at least 3 seconds.
3) Shift selector lever to P position (A/T) or neutral position (M/T).
4) Turn ignition switch OFF and wait at least 10 seconds.
5) Turn ignition switch ON and wait at least 1 second.
6) Shift selector lever to D position (A/T) or 1st position (M/T), and wait at least 3 seconds.
7) Shift selector lever to P position (A/T) or neutral position (M/T).
8) Turn ignition switch OFF, wait at least 10 seconds, and then turn ON.
9) Check DTC.
10) If DTC is detected, go to "Diagnosis Procedure".

Procedure for Malfunction C

With SDT

1) Turn ignition switch ON and wait at least 1 second.
2) Shift selector lever to D position (A/T) or 1st position (M/T), and wait at least 3 seconds.
3) Shift selector lever to P or N position (A/T) or neutral position (M/T).
4) Start engine and let it idle for 3 seconds.
5) Check DTC.
6) If DTC is detected, go to "Diagnosis Procedure".

Diagnosis Procedure

1. CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY

1 Remove the intake air duct.
2 Check if a foreign matter is caught between the throttle valve and the housing.






OK or NG
OK
GO TO 2.
NG
Remove the foreign matter and clean the electric throttle control actuator inside, and then perform throttle valve closed position learning. Refer to [Throttle Valve Closed Position Learning] Throttle Valve Closed Position Learning.

2. REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR

1 Replace the electric throttle control actuator. Refer to [Intake Manifold Collector: Exploded View] Intake Manifold Collector Exploded View.
2 Perform [Throttle Valve Closed Position Learning] Throttle Valve Closed Position Learning.
3 Perform [Idle Air Volume Learning] Idle Air Volume Learning.
