CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P0711

DTC Code DTC Name
P0711 Transmission Fluid Temperature Sensor "A" Circuit Range / Performance

DESCRIPTION

The CVT fluid temperature sensor converts the fluid temperature into a resistance value which is detected by the ECM.

The sensor resistance changes with the CVT fluid temperature. As the temperature rises, the sensor resistance decreases. The ECM applies voltage to the temperature sensor through ECM terminal THO1 and calculates the fluid temperature based on the voltage signal.

Tech Tips

The CVT fluid temperature is likely to increase under conditions such as towing, climbing hills and in traffic.

DTC No.

 Trouble Area
P0711

  1. The intake air and engine coolant temperatures are higher than -10°C (14°F) at engine start, and the vehicle is driven for over 18 minutes at 7 km (4.0 miles) or more.

  2. The CVT fluid temperature is below 20°C (68°F).

  3. 3 seconds

  4. 2-trip detection logic

  • CVT fluid level

  • Continuously variable transaxle assembly (CVT fluid temperature sensor)

  1. The engine coolant temperature is below 35°C (95°F) at engine start.

  2. The CVT fluid temperature is 100°C (212°F) or higher.

  3. 10 seconds

  4. 2-trip detection logic

MONITOR DESCRIPTION

The CVT fluid temperature sensor converts the CVT fluid temperature to an electrical resistance value. Based on the resistance, the ECM determines the CVT fluid temperature and detects open or short circuits in the CVT fluid temperature circuit.

After driving the vehicle for a certain period, the CVT fluid temperature should increase. If the CVT fluid temperature remains below 20°C (68°F), the ECM interprets this as a fault and illuminates the MIL. When the engine coolant temperature reaches 35°C (95°F) after a cold engine start, if the CVT fluid temperature is 100°C (212°F) or higher, the ECM also determines this as a fault, illuminates the MIL, and stores this DTC.

  • Perform initialization when parts related to the continuously variable transaxle are replaced Click here.

  • Check that no DTCs are stored after performing initialization Click here.

PROCEDURE


  1. CHECK DTC OUTPUT (IN ADDITION TO DTC P0711)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

    5. Read the DTCs using the GTS.

      Tech Tips

      If any DTCs other than P0711 are output, perform troubleshooting for those DTCs first.
