Inspection Procedure

HINT:

Read freeze frame data using the intelligent tester. The ECM (Included in HV control ECU) 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 ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2119) 
    1. Connect the intelligent tester to the DLC3.
    2. Turn the ignition switch to the ON position.
    3. Turn the tester ON.
    4. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.
    5. Read the DTCs.

      HINT:

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

    B: GO TO  DTC CHART  

    A: Go to next step 

  2. CHECK WHETHER DTC OUTPUT RECURS (DTC P2119) 
    1. Connect the intelligent tester to the DLC3.
    2. Put the engine in inspection mode (See INSPECTION MODE PROCEDURE ).
    3. Start the engine.
    4. Turn the tester ON.
    5. Clear the DTCs (See DTC CHECK / CLEAR ).
    6. Allow the engine to idle for 15 seconds.
      CAUTION: Exercise extreme care and take precautions at steps (f) and (g) below. Failure to do so may result in the vehicle unexpectedly rolling away.
    7. Securely apply the parking brake and move the gear selector lever to the D position.
    8. While depressing the brake pedal securely, fully depress the accelerator pedal for 5 seconds.
    9. On the tester, enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.
    10. Read the DTCs.

      HINT:

      The output voltage of the throttle position sensor can be checked during step (g) 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, enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST / PRIMARY / THROTTLE POS #1.

    OK: No DTC output. 

    NG: REPLACE THROTTLE BODY ASSEMBLY 

    OK: NORMAL
