DTC Trouble diagnosis name DTC detection condition Possible causes
P0711 Transmission Fluid Temperature Sensor A Circuit Range/ Performance Under the following diagnosis conditions, CVT fluid temperature does not rise to 10C (50F) after driving for a certain period of time with the TCM-received fluid temperature sensor value between −40C (−40F) and 9C (48.2F).

- Diagnosis condition

- Selector lever: "D" position

- Vehicle speed: 10 km/h (7 MPH) or more

- Engine speed: 450 rpm or more

- Accelerator pedal position: 1.0/8 or more

- TCM power supply voltage: More than 11 V

 CVT fluid temperature sensor
When the condition of the final judgment is satisfied after satisfying that of the provisional judgment:

- Provisional judgment: All of the following conditions are satisfied within 2 seconds after the ignition switch is turned ON.

- U0073, U0100, P0712 and P0713 are not detected.

- CAN communication is normal.

- TCM power supply voltage: More than 11 V

- The difference between CVT fluid temperature and engine coolant temperature is 37C (98.6F) or more, or −27C (−16.6F) or less.

- Final judgment: When all of the following conditions are satisfied and this state is maintained for 300 seconds:

- ECM is normal.

- Provisional judgment is satisfied.

DTC CONFIRMATION PROCEDURE

CAUTION: Always drive vehicle at a safe speed.

1.PREPARATION BEFORE WORK

If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.

>> GO TO 2.

2.CHECK CVT FLUID TEMPERATURE SENSOR FUNCTION

With CONSULT

  1.  Cool the engine.
  2.  Turn ignition switch ON. CAUTION: Never start the engine.
  3.  Select "FLUID TEMP" in "Data Monitor" in "TRANSMISSION".
  4.  Select "COOLANT TEMP/S" in "Data Monitor" in "ENGINE".
  5.  Check temperature difference between CVT fluid and engine coolant.

With GST

  1. Complete engine diagnoses P0111, P0116, and P0196.
  2. After starting the engine start, run the engine at idle for 5 minutes.
  3. Check the DTC.

Is the temperature calculated by subtracting engine coolant temperature from CVT fluid temperature more than 37C (98.6F) or is it less than −27C (−16.6F)? (With CONSULT)/Is "P0711" detected? (With GST)

YES >> Go to TM "Diagnosis Procedure".

NO-1 [With CONSULT: "FLUID TEMP" is 10C (50F) or more]>>INSPECTION END

NO-2 [With CONSULT: "FLUID TEMP" is 9C (48.2F) or less]>>GO TO 3.

NO-3 (With GST)>>GO TO 3.

3.CHECK DTC DETECTION

With CONSULT

  1. Select "SLCT LVR POSI", "VSP SENSOR", "ACCELE POSI SEN 1", "FLUID TEMP" in "Data Monitor" in "TRANSMISSION".
  2. Record CVT fluid temperature.
  3. Start the engine and wait for at least 3 minutes.
  4. Drive the vehicle for the total minuets specified in the Driving time column below with the following conditions satisfied.

SLCT LVR POSI : D VSP SENSOR : 10 km/h (7 MPH) or more ACCELE POSI SEN 1 : 1.0/8 or more

    5.   Perform "Self Diagnostic Results" in "TRANSMISSION".

With GST

    1.   Cool the engine.

    2.   Start the engine and wait for at least 3 minutes.

    3.   Drive the vehicle and maintain the following conditions for 21 minutes or more.

Selector lever : D position Vehicle speed : 10 km/h (7 MPH) or more Accelerator pedal opening : 1.0/8 or more

    4.   Check the DTC.

Is "P0711" detected?

YES >> Go to TM "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK CVT FLUID TEMPERATURE SENSOR

  1. Turn ignition switch OFF.
  2. Disconnect CVT unit connector.
  3. Check CVT fluid temperature sensor. Refer to TM "Component Inspection (CVT Fluid Temperature Sensor)".

Is the inspection result normal?

YES >> Check intermittent incident. Refer to GI "Intermittent Incident".

NO >> Repair or replace malfunctioning parts.

Component Inspection (CVT Fluid Temperature Sensor)

1.CHECK CVT FLUID TEMPERATURE SENSOR

Check resistance between CVT unit connector terminals.

Is the inspection result normal?

YES >> INSPECTION END

NO >> There is a malfunction of CVT fluid temperature sensor. Replace transaxle assembly. Refer to TM "Removal and Installation".
