DTC P0711, P0712, P0713 [5R55S]

id0502c1814600

DTC P0711

Transmission fluid temperature (TFT) sensor malfunction (ATF temperature no change)

DTC P0712

Transmission fluid temperature (TFT) sensor circuit malfunction (short to ground)

DTC P0713

Transmission fluid temperature (TFT) sensor circuit malfunction (open circuit)
DETECTION CONDITION
•  P0711: ATF temperature signal continually reading cold or hot
•  P0712: TCM detects that ATF signal output from ATF sensor is 157° C {315° F} or more
•  P0713: TCM detects ATF signal from ATF sensor is–40° C {–40° F} or less
POSSIBLE CAUSE
•  TFT sensor malfunction
•  Short to ground in wiring harness between AT connector terminal K and TCM terminal AY
•  Short to ground in wiring harness between AT connector terminal L and TCM terminal BH
•  Open circuit supply in wiring harness between AT connector terminal K and TCM terminal AY
•  Open circuit supply in wiring harness between AT connector terminal L and TCM terminal BH
•  Damaged connectors between AT connector and TCM
•  TCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT AT CONNECTOR FOR POOR CONNECTION
•  Turn the engine switch to the LOCK position.
•  Inspect the AT connector connection.
•  Disconnect the AT connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is the connection normal?
Yes
Go to the next step.
No
Repair or replace the connector and/or terminals, then go to Step 8.
4
INSPECT TFT SENSOR
•  Inspect the TFT sensor.
•  Is the digital TR sensor normal?
Yes
Go to the next step.
No
Replace the TFT sensor, then go to Step 8.
5
INSPECT TCM CONNECTOR FOR POOR CONNECTION
•  Disconnect the TCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is the connection normal?
Yes
Go to the next step.
No
Repair or replace the connector and/or terminals, then go to Step 8.
6
INSPECT TFT SENSOR CIRCUIT FOR SHORT TO GROUND
•  Inspect for continuity between the AT terminals (wiring harness-side) and body ground.
―  K and body ground
―  L and body ground
•  Is there continuity?
Yes
Repair or replace the wiring harness, then go to Step 8.
No
Go to the next step.
7
INSPECT TFT SENSOR CIRCUIT FOR OPEN CIRCUIT
•  Inspect the following AT terminals (wiring harness-side) and TCM terminals (wiring harness-side):
―  K and AY
―  L and BH
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 8.
8
VERIFY TROUBLESHOOTING OF DTC P0711, P0712 OR P0713 COMPLETED
•  Make sure to reconnect all the disconnected connectors.
•  Clear the DTC from the memory using the IDS/PDS.
•  Perform the “After Repair Procedure”.
•  Is the same DTC present?
Yes
Replace the TCM, then go to the next step.
(See TCM REMOVAL/INSTALLATION [5R55S].)
No
Go to the next step.
9
VERIFY DTCS
•  Are DTCs except for P0711, P0712 and P0713 output?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [5R55S].)
No
DTC troubleshooting completed.
