Title: G16E-GTS (ENGINE CONTROL): SFI SYSTEM: P024313; Turbocharger/Supercharger Wastegate Solenoid "A" Circuit Open; 2023 - 2025 MY GR Corolla [09/2022 -        ]

DTC

P024313

Turbocharger/Supercharger Wastegate Solenoid "A" Circuit Open

DESCRIPTION

The waste gate valve is built into the turbine housing and is operated by the vacuum regulating valve assembly. The ECM uses duty control to open and close the vacuum regulating valve assembly. The amount of opening is controlled according to the operation status.

DTC No.

Note

P024313

Turbocharger/Supercharger Wastegate Solenoid "A" Circuit Open

Open or short in vacuum regulating valve assembly circuit for 1 second or more (1 trip detection logic)

  • Open or short in vacuum regulating valve assembly circuit
  • Vacuum regulating valve assembly
  • ECM

CONFIRMATION DRIVING PATTERN

HINT:

  • After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

    Click here 2023 - 2025 MY GR Corolla [09/2022 -        ]; G16E-GTS (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR

  • When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

    Click here 2023 - 2025 MY GR Corolla [09/2022 -        ]; G16E-GTS (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR

  1. Connect the GTS to the DLC3.
  2. Turn the ignition switch to ON.
  3. Turn the GTS on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the ignition switch off and wait for at least 30 seconds.
  6. Turn the ignition switch to ON.
  7. Turn the GTS on.
  8. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher [A].
  9. Accelerate to 50 km/h (31 mph) or more with the accelerator pedal fully depressed [B].

    CAUTION:

    When performing the confirmation driving pattern, obey all speed limits and traffic laws.

  10. Enter the following menus: Powertrain / Engine / Trouble Codes [C].
  11. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  12. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  13. Input the DTC: P024313.
  14. Check the DTC judgment result.

    GTS Display

    Description

    NORMAL

    • DTC judgment completed
    • System normal

    ABNORMAL

    • DTC judgment completed
    • System abnormal

    INCOMPLETE

    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    HINT:

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE, perform steps [B] and [C] again.
    • [A] to [C]: Normal judgment procedure.

      The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

    • When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

WIRING DIAGRAM

CAUTION / NOTICE / HINT

HINT:

Read freeze frame data using the GTS. 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.
