id050221801400

DTC P0713

Transaxle fluid temperature (TFT) sensor circuit malfunction (open circuit)

DETECTION CONDITION

• If the TCM detects the following condition for 150 s or more, the TCM determines that the TFT sensor circuit has a malfunction.
- TFT sensor voltage 4.67 V or more and vehicle speed 20 km/h {12 mph} or more
Diagnostic support note:
• This is a continuous monitor (CCM).
• The MIL illuminates if the TCM detects the above malfunction conditions during the first drive cycle.
• The PENDING CODE is available if the TCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA is available.
• The AT warning light illuminates.
• The DTC is stored in the TCM memory.

POSSIBLE CAUSE

• TFT sensor malfunction
• Open circuit in wiring harness between TFT sensor and transaxle connector (primary) terminal E
• Open circuit in wiring harness between TFT sensor and transaxle connector (primary) terminal H
• Open circuit in wiring harness between transaxle connector (primary) terminal E and TCM terminal 2M
• Open circuit in wiring harness between transaxle connector (primary) terminal H and TCM terminal 2O
• Damaged connectors between TFT sensor 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 REPAIR INFORMATION AVAILABILITY

• Verify related Service Bulletins and/or on-line repair information availability.
• Is any related repair information available?
Yes
Perform repair or diagnosis according to the available repair information.
• If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3

VERIFY CURRENT INPUT SIGNAL STATUS

• Turn the ignition switch to the ON position (engine off).
• Measure the voltage at TCM terminal 2M.
• Is the voltage 4.67 V or less?
Yes
Go to the intermittent concern troubleshooting procedure.
No
Go to the next step.
4

INSPECT TRANSAXLE CONNECTOR FOR POOR CONNECTION

• Turn the ignition switch to the LOCK position.
• Inspect transaxle connector (primary) connection.
• Disconnect the transaxle connector (primary).
• 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 10.
5

INSPECT TFT SENSOR CIRCUIT

• Turn the ignition switch to the ON position (engine off).
• Measure the voltage at TCM terminal 2M when connect between transaxle connector (primary) terminals E and H (wiring harness-side) using jumper wire.
• Verify that voltage changes to 0.06 V or less.
• Does the voltage change?
Yes
Go to the next step.
No
Go to Step 7.
6

INSPECT TFT SENSOR CIRCUIT FOR OPEN CIRCUIT

• Inspect for continuity between transaxle connector (primary) terminals (transaxle case side) E and H.
• Is there continuity?
Yes
Replace the TFT sensor, then go to Step 10.
No
Repair or replace the wiring harness, then go to Step 10.
7

INSPECT TCM CONNECTOR FOR POOR CONNECTION

• Turn the ignition switch to the LOCK position.
• 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 10.
8

INSPECT WIRING HARNESS FOR OPEN CIRCUIT

• Disconnect the transaxle connector (primary).
• Connect the TCM connector.
• Turn the ignition switch to the ON position (engine off).
• Inspect the voltage at transaxle connector (primary) terminal E (vehicle wiring harness-side).
• Is the voltage 5 V?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 10.
9

INSPECT TRANSAXLE CONNECTOR CIRCUIT FOR OPEN CIRCUIT

• Turn the ignition switch to the LOCK position.
• Inspect for continuity between transaxle connector (primary) terminal H (wiring harness-side) and body ground.
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to the next step.
10

VERIFY TROUBLESHOOTING OF DTC P0713 COMPLETED

• Make sure to reconnect all the disconnected connectors.
• Clear the DTC from the memory using the WDS or equivalent.
• Drive the vehicle under the following condition for 150 s or more.
- Vehicle speed (VSS PID) 20 km/h {12 mph} or more.
• Is the same DTC present?
Yes
Replace the TCM, then go to the next step.
No
Go to the next step.
11

VERIFY AFTER REPAIR PROCEDURE

• Perform the "After Repair Procedure".
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
