DTC No. INF Code DTC Detection Condition Trouble Area
P0711 883

As a result of comparing the fluid temperature and coolant temperature with the power switch on (READY), the fluid temperature exceeds a specified level while the coolant temperature is less than the specified level.

(2 trip detection)


  • Wire harness or connector

  • Hybrid vehicle transmission assembly

  • Power management control ECU

  • Transmission wire (transmission fluid temperature sensor)

Tech Tips

DTC P0711-833 will be set if the engine coolant temperature changes from 95°F (35°C) or less to 140°F (60°C) after the power switch is turned on (READY).

      Rear view of wire harness connector

      (to Power Management Control ECU)

      Disconnect the connector from the power management control ECU.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      A36-33 (THO) - A36-32 (ETHO) 50°F (10°C) 5.0 to 8.0 kΩ
      A36-33 (THO) - A36-32 (ETHO) 230°F (110°C) 0.22 to 0.28 kΩ
    3. Connect the power management control ECU connector.


    NG
    OK
  4. CLEAR DTC


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

    4. Read and record the DTCs and freeze frame data.

      *a T/M TEMP
      *b Normal
      *c Malfunction

      Read the Data List.

      OK
      The T/M Oil Temperature value is within the normal range and does not fluctuate.
    5. Turn the power switch off.


    NG
    OK
  6. CHECK FOR INTERMITTENT PROBLEMS

  7. CHECK FLUID LEAKS


    1. Check for fluid leaks from the hybrid vehicle transmission assembly.

      OK
      There are no fluid leaks.

    NG
    OK
  8. CHECK CONNECTOR CONNECTION CONDITION (TRANSMISSION WIRE CONNECTOR)


    1. A01FQ02

      Check the connection of the transmission wire connector Click here.

      OK
      The connector is connected securely and there are no contact problems.

    NG
    OK
  9. CHECK HARNESS AND CONNECTOR (POWER MANAGEMENT CONTROL ECU - TRANSMISSION WIRE)

      Disconnect the power management control ECU connector.

    2. Disconnect the transmission wire connector.

    3. Turn the power switch on (IG).

    4. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      A36-33 (THO) - Body ground Power switch on (IG) Below 1 V
      A36-32 (ETHO) - Body ground Power switch on (IG) Below 1 V

      Note

      Turning the power switch on (IG) with the power management control ECU connectors disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

    5. Turn the power switch off.

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      A36-33 (THO) - F52-9 (THO) Power switch off Below 1 Ω
      A36-32 (ETHO) - F52-3 (E) Power switch off Below 1 Ω
      A36-33 (THO) or F52-9 (THO) - Body ground and other terminals Power switch off 10 kΩ or higher
      A36-32 (ETHO) or F52-3 (E) - Body ground and other terminals Power switch off 10 kΩ or higher
    7. Connect the power management control ECU connector.

    8. Connect the transmission wire connector.
