DTC P2119 Throttle Actuator Control Throttle Body Range / Performance


DESCRIPTION

The electronic throttle control system is composed of the throttle actuator, throttle position sensor, accelerator pedal position sensor, and ECM. The ECM operates the throttle actuator to regulate the throttle valve in response to driver inputs. The throttle position sensor detects the opening angle of the throttle valve, and provides the ECM with feedback so that the throttle valve can be appropriately controlled by the ECM.

DTC No.

  1. Electronic throttle control system
  2. ECM

FAIL-SAFE

When this DTC, as well as other DTCs relating to electronic throttle control system malfunctions, is set, the ECM enters fail-safe mode. During fail-safe mode, the ECM cuts the current to the throttle actuator off, and the throttle valve is returned to a 6° throttle angle by the return spring. The ECM then adjusts the engine output by controlling the fuel injection (intermittent fuel-cut) and ignition timing, in accordance with the accelerator pedal opening angle, to allow the vehicle to continue at a minimal speed. If the accelerator pedal is depressed gently, the vehicle can be driven slowly. Fail-safe mode continues until a pass condition is detected, and the ignition switch is then turned off.

INSPECTION PROCEDURE

УКАЗАНИЕ:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
1.CHECK WHETHER DTC OUTPUT RECURS (DTC P2119)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG) and turn the tester on.

  1. Clear the DTCs (See page Нажмите здесь).

  1. Allow the engine to idle for 15 seconds.

    ПРЕДОСТЕРЕЖЕНИЕ:
    Exercise extreme care and take precautions in steps "A" and "B" below. Failure to do so may result in the vehicle unexpectedly rolling away.

  1. Securely apply the parking brake and move the gear selector lever to the D position (Step "A").

  1. While depressing the brake pedal securely, fully depress the accelerator pedal for 5 seconds (Step "B").

  1. Select the following menu items: Powertrain / Engine and ECT / DTC.

  1. Read the DTCs.

    УКАЗАНИЕ:
    The output voltage of the throttle position sensor can be checked during step "B" using the intelligent tester. Variations in the output voltage indicate that the throttle actuator is in operation. To check the output voltage using the intelligent tester, select the following menu items: Powertrain / Engine and ECT / Data List / Throttle Position No. 1 or Throttle Position No. 2.
