P2119 ELECTRIC THROTTLE CONTROL ACTUATOR EC-823 < COMPONENT DIAGNOSIS > [VQ40DE] C D E F G H I J K L M A EC N P O P2119 ELECTRIC THROTTLE CONTROL ACTUATOR Component Description INFOID:0000000005273838 Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc. On Board Diagnosis Logic INFOID:0000000005273839 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 INFOID:0000000005273840 NOTE: PROCEDURE FOR MALFUNCTION C. • If DTC Confirmation Procedure has been previously conducted, always perform the following before con- ducting 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 . DTC No. Trouble diagnosis name DTC detecting condition Possible cause P2119 Electric throttle control A) Electric throttle control actuator does not func- • Electric throttle control actuator B) Throttle valve opening angle in fail-safe mode is C) ECM detects that the throttle valve is stuck Detected items Engine operating condition in fail-safe mode Malfunction A The ECM controls the electric throttle actuator by regulating the throttle opening around the idle position. Malfunction B ECM controls the electric throttle control actuator by regulating the throttle opening to 20 degrees or less. Malfunction C While the vehicle is driving, it slows down gradually by fuel cut. After the vehicle stops, the engine stalls. |
