SFI SYSTEM, Diagnostic DTC:P2119

DTC Code DTC Name
P2119 Throttle Actuator Control Throttle Body Range / Performance

DESCRIPTION

The Electronic Throttle Control System (ETCS) is composed of the throttle actuator, Throttle Position (TP) sensor, Accelerator Pedal Position (APP) sensor and ECM. The ECM operates the throttle actuator to regulate the throttle valve in response to driver inputs. The TP 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. DTC Detection Condition Trouble Area
P2119 The throttle valve opening angle continues to vary greatly from the target opening angle (1 trip detection logic).

  • ETCS

  • ECM

FAIL-SAFE

When this DTC as well as other DTCs relating to ETCS (Electronic Throttle Control System) malfunctions are stored, the ECM enters fail-safe mode. During fail-safe mode, the ECM cuts the current to the throttle actuator, and the throttle valve is returned to a 6.5° opening 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 position, to allow the vehicle to continue at a minimal speed. If the accelerator pedal is depressed firmly and gently, the vehicle can be driven slowly. Fail-safe mode continues until a pass condition is detected and the engine switch is turned off.

INSPECTION PROCEDURE

Tech Tips

Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE


  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2119)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG) and turn the tester on.

    3. Enter the following menus: Powertrain / Engine and ECT / DTC.

    4. Read DTCs.

      Tech Tips

      If any DTCs other than P2119 are output, troubleshoot those DTCs first.

    Component without harness connected

    (Throttle Body)

    1. Disconnect the B7 throttle body connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      2 (M+) - 1 (M-) 20°C (68°F) 0.3 to 100 Ω

    3. Reconnect the throttle body connector.

  4. CHECK WHETHER DTC OUTPUT RECURS (DTC P2119)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG) and turn the tester on.

    3. Clear DTCs Click here.

    4. Start the engine and allow the engine to idle for 15 seconds.

    5. Fully depress and release the accelerator pedal quickly (to fully open and close the throttle valve).

    6. Enter the following menus: Powertrain / Engine and ECT / DTC.

    7. Read DTCs.

      OK
      No DTC output.

      Tech Tips

      The output voltage of the throttle position sensor can be checked using the intelligent tester. Variations in the output voltage indicate that the throttle actuator is operating. To check the output voltage using the intelligent tester, enter the following menus: Powertrain / Engine and ECT / Data List / Throttle Position No.1 or Throttle Position No.2.
