id0502a18014a7

DTC P0713

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

DETECTION CONDITION

• If TCM detects either of the following conditions for 150 seconds or more, TCM determines that TFT sensor circuit has a malfunction.
- TFT sensor voltage is 4.67 V or above and vehicle speed 20 km/h {12 mph} or above.
Diagnostic support note:
• This is a continuous monitor (CCM).
• MIL illuminates if TCM detects the above malfunction conditions during first drive cycle.
• PENDING CODE is not available.
• FREEZE FRAME DATA is available.
• AT warning light illuminates.
• DTC is stored in the TCM memory.

POSSIBLE CAUSE

• TFT sensor malfunction.
• Open circuit between TFT sensor terminal A and ATX connector terminal E.
• Open circuit between TFT sensor terminal B and ATX connector terminal H.
• Open circuit between ATX connector terminal E and TCM terminal 2M.
• Open circuit between ATX connector 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 FREEZE FRAME PID DATA been recorded?
Yes
Go to next step.
No
Record FREEZE FRAME PID DATA on repair order, then go to next step.
2

VERIFY RELATED REPAIR INFORMATION AVAILABILITY

• Check for related Service Bulletins availability.
• Is any related repair information available?
Yes
Perform repair or diagnosis according to available repair information.
• If vehicle is not repaired, go to next step.
No
Go to next step.
3

VERIFY CURRENT INPUT SIGNAL STATUS

• Turn ignition key to OFF.
• Connect breakout box to TCM.
• Turn ignition key to ON (engine off).
• Measure the voltage at TCM terminal 2M.
• Are voltage readings below 4.67 V?
Yes
Go to intermittent concern troubleshooting procedure.
No
Go to next step.
4

INSPECT ATX CONNECTOR FOR POOR CONNECTION

• Turn ignition key to OFF.
• Inspect ATX connector connection.
• Disconnect ATX connector.
• Check for poor connection (damaged/pulled-out terminals, corrosion etc.).
• Is connection okay?
Yes
Go to next step.
No
Repair or replace connector and/or terminal, then go to Step 11.
5

INSPECT TFT SENSOR CIRCUIT

• Turn ignition key to ON (engine off).
• Measure the voltage at TCM terminal 2M when connect between ATX connector terminals E and H (vehicle harness-side) using jumper wire.
• Verify that voltage changes to 0.06 V or below.
• Does voltage change?
Yes
Go to next step.
No
Go to Step 8.
6

INSPECT TFT SENSOR CONNECTOR FOR POOR CONNECTION

• Turn ignition key to OFF.
• Remove valve body cover.
• Disconnect TFT sensor connector.
• Check for poor connection (damaged/pulled-out terminals, corrosion, etc.).
• Is connection okay?
Yes
Go to next step.
No
Repair or replace connector and/or terminal or replace TFT sensor, then go to Step 11.
7

INSPECT TFT SENSOR CIRCUIT FOR OPEN CIRCUIT

• Check for continuity between TFT sensor terminals (harness-side) and ATX connector terminals (transaxle case side).
- ATX connector terminal E and TFT sensor terminal A
- ATX connector terminal H and TFT sensor terminal B
• Is there continuity?
Yes
Replace TFT sensor, then go to Step 11.
No
Repair or replace harness, then go to Step 11.
8

INSPECT TCM CONNECTOR FOR POOR CONNECTION

• Turn ignition key to OFF.
• Disconnect TCM connector.
• Check for poor connection (damaged/pulled-out terminals, corrosion, etc.).
• Is connection okay?
Yes
Go to next step.
No
Repair or replace connector and/or terminal, then go to Step 11.
9

INSPECT HARNESS FOR OPEN CIRCUIT

• Disconnect ATX connector.
• Connect the TCM connector.
• Turn ignition key to ON (engine off).
• Inspect voltage at ATX connector terminal E (vehicle harness-side).
• Is voltage 5 V?
Yes
Go to next step.
No
Repair or replace harness, then go to Step 11.
10

INSPECT ATX CONNECTOR CIRCUIT FOR OPEN CIRCUIT

• Turn ignition key to OFF.
• Inspect continuity between ATX connector terminal H (vehicle harness-side) and body ground.
• Is there continuity?
Yes
Go to next step.
No
Repair or replace harness, then go to next step.
11

VERIFY TROUBLESHOOTING OF DTC P0713 COMPLETED

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

VERIFY AFTER REPAIR PROCEDURE

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