Toyota Avalon Service & Repair Manual: Generator Temperature Sensor Voltage Out of Range (P0A361C,P0A361F)

Toyota Avalon Service & Repair Manual / Engine / Hybrid / Battery Control / Hybrid Control System / Generator Temperature Sensor Voltage Out of Range (P0A361C,P0A361F)

DTC SUMMARY

MALFUNCTION DESCRIPTION

These DTCs are stored when the generator temperature sensor output is abnormal. The cause of this malfunction may be one of the following:

Hybrid vehicle control ECU malfunction
  • Hybrid vehicle control ECU internal malfunction
Generator temperature sensor malfunction
  • Internal generator temperature sensor malfunction
  • Open or short in generator temperature sensor
Wire harness between the generator temperature sensor and hybrid vehicle control ECU
  • The connectors are not connected properly
  • Foreign matter or water on the connector terminals
  • Open or short in wire harness

HINT:

If any of these DTCs are stored, the generator temperature sensor is malfunctioning and the self-protection function may not operate. Therefore under certain high load driving condition, the temperature of the generator (MG1) becomes high. If the self-protection function does not operate, the generator (MG1) may malfunction and cause the vehicle to enter fail-safe mode.

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

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

    Click here

DTC P0A361C
  1. Connect the Techstream to the DLC3.
  2. Turn the power switch on (IG) and turn the Techstream on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the power switch off.
  5. Leave the vehicle as is for 5 hours or more and then check the values of the Data List items "Generator Temperature", "Motor Temperature" and "Inverter Coolant Water Temperature".[*1]
  6. Turn the power switch on (IG) and turn the Techstream on.[*2]

    HINT:

    [*1] to [*2]: Normal judgment procedure.

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

  7. Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
  8. Check the DTC judgment result.

    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 or N/A, perform the normal judgment procedure again.
DTC P0A361F
  1. Connect the Techstream to the DLC3.
  2. Turn the power switch on (IG) and turn the Techstream on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the power switch off and wait for 2 minutes or more.
  5. Turn the power switch on (IG) and turn the Techstream on.
  6. With power switch on (IG) and wait for 5 seconds or more.[*1]

    HINT:

    [*1] : Normal judgment procedure.

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

  7. Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
  8. Check the DTC judgment result.

    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 or N/A, perform the normal judgment procedure again.
