DTC DETECTION LOGIC

DTC Trouble diagnosis name DTC detection condition Possible causes
P0711 Transmission Fluid Temperature Sensor "A" Circuit Range/ Performance Under the following diagnosis conditions, A/T fluid temperature does not rise to 15C (59F) after driving for a certain period of time with the TCM-received fluid temperature sensor value between −40C (−40F) and 14C (57.2F).

- 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
A/T 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 A/T fluid temperature and engine coolant temperature is 38C (100.4F) 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 A/T FLUID TEMPERATURE SENSOR FUNCTION

With CONSULT

  1. Cool the engine.
  2. Turn ignition switch ON.

CAUTION: Never start the engine.

  1. Select "FLUID TEMP" in "Data Monitor" in "TRANSMISSION".
  2. Select "COOLANT TEMP/S" in "Data Monitor" in "ENGINE".
  3. Check temperature difference between A/T 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 A/T fluid temperature more than 38C (100.4F) 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 15C (59F) or more]>>INSPECTION END

NO-2 [With CONSULT: "FLUID TEMP" is 14C (57.2F) or less]>>GO TO 3.

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

3.CHECK DTC DETECTION

With CONSULT

  1. Select "SLCT LVR POSI", "VHCL/S SE-AT", "ACCELE POSI", "FLUID TEMP" in "Data Monitor" in "TRANSMISSION".
  2. Record A/T 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

VHCL/S SE-AT : 10 km/h (7 MPH) or more

ACCELE POSI : 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

Check the DTC.

Is "P0711" detected?

YES >> Go to TM, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK A/T FLUID TEMPERATURE SENSOR

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

Is the check result normal?

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

NO >> Repair or replace the malfunctioning parts.

Component Inspection (A/T Fluid Temperature Sensor)

1.CHECK A/T FLUID TEMPERATURE SENSOR

Measure the resistance between the A/T unit connector terminals. 

Is the check result normal?

YES >> INSPECTION END

NO >> There is a malfunction of the A/T fluid temperature sensor. Replace the transaxle assembly. Refer to TM, "Removal and Installation".
