Title: A25A-FKS (ENGINE CONTROL): SFI SYSTEM (w/o Canister Pump Module): P06579E; Actuator Supply Voltage "A" Stuck On; 2019 - 2020 MY RAV4 [11/2018 - 08/2020]

DTC

P06579E

Actuator Supply Voltage "A" Stuck On

MONITOR DESCRIPTION

The ECM monitors the output voltage to the throttle actuator. This self-check ensures that the ECM is functioning properly. The output voltage is usually 0 V when the ignition switch is turned off. If the output voltage is 7 V or higher when the ignition switch is turned off, the ECM will illuminate the MIL and store this DTC when the ignition switch is turned to ON.

DTC No.

CONFIRMATION DRIVING PATTERN

  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch to ON.
  3. Turn the Techstream on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the Techstream off.
  6. Turn the ignition switch off.
  7. Disconnect the Techstream.
  8. Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.
  9. Connect the cable to the negative (-) battery terminal.
  10. Turn the ignition switch to ON.
  11. Wait 10 seconds or more.
  12. Turn the ignition switch off.
  13. Wait 15 seconds or more.
  14. Connect the Techstream to the DLC3.
  15. Turn the ignition switch to ON.
  16. Turn the Techstream on.
  17. Wait 5 seconds or more.
  18. Enter the following menus: Powertrain / Engine / Trouble Codes.
  19. 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.
  20. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  21. Input the DTC: P06579E.
  22. Check the DTC judgment result.

    Techstream 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 is NORMAL, the system is normal.
    • If the judgment result is ABNORMAL, the system is malfunctioning.

CAUTION / NOTICE / HINT

HINT:

Read Freeze Frame Data using the Techstream. 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.

PROCEDURE

1.

CLEAR DTC

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Clear the DTCs.

Powertrain > Engine > Clear DTCs

(e) Turn the ignition switch off.
