EC-844 < COMPONENT DIAGNOSIS > [VK56DE] P2119 ELECTRIC THROTTLE CONTROL ACTUATOR P2119 ELECTRIC THROTTLE CONTROL ACTUATOR Component Description INFOID:0000000005257859 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 current opening angle of the throttle valve is detected by the throttle position sensor. The throttle position sensor provides feedback to the ECM, when opens/closes the throttle valve in response to driving conditions via the throttle control motor. On Board Diagnosis Logic INFOID:0000000005257860 This self-diagnosis has one trip detection logic. FAIL-SAFE MODE When the malfunction is detected, ECM enters fail-safe mode and the MIL illuminates. DTC Confirmation Procedure INFOID:0000000005257861 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 procedure before conducting the next test. 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. . PROCEDURE FOR MALFUNCTION C 1. Turn ignition switch ON and wait at least 1 second. DTC No. Trouble diagnosis name DTC detecting condition Possible cause P2119 Electric throttle control A) Electric throttle control actuator does not function • Electric throttle control actuator B) Throttle valve opening angle in fail-safe mode is C) ECM detects that the throttle valve is stuck open. 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. 2010 Pathfinder |
