DTC 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 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.




On Board Diagnosis Logic
This self-diagnosis has the one trip detection logic.






FAIL-SAFE MODE
When the malfunction is detected, ECM enters fail-safe mode and the MIL lights up.









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 turn ignition switch OFF and wait at least 10 seconds before conducting the next test.

PROCEDURE FOR MALFUNCTION A AND B
1. Turn ignition switch ON and wait at least 1 second.
2. Set shift lever to D position (CVT) or 1st position (M/T), and wait at least 3 seconds.
3. Set shift lever to P position (CVT) 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. Set shift lever to D position (CVT) or 1st position (M/T), and wait at least 3 seconds.
7. Set shift lever to P position (CVT) 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 SEE Diagnosis Procedure.

PROCEDURE FOR MALFUNCTION C
1. Turn ignition switch ON and wait at least 1 second.
2. Set shift lever to D position (CVT) or 1st position (M/T) and wait at least 3 seconds.
3. Set shift lever to N, P position (CVT) or Neutral (M/T) position.
4. Start engine and let it idle for 3 seconds.
5. Check DTC.
6. If DTC is detected, go to SEE 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 (1) and the housing.
- Arrow Indicates Vehicle Front
- This illumination is shows the view with intake air duct removed.
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. Component.
2.REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR
Replace the electric throttle control actuator. Component.
