DTC P0713 [JA5A-EL]

BME050218901209

DTC P0713

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

DETECTION CONDITION

• If the vehicle speed is 20 km/h {12.4 mph} or greater, and a signal from the TFT sensor is 2.4 V or above for 300 s or more, the TCM determines that there is a malfunction.
Diagnostic support note:
• This is a continuous monitor (CCM).
• The MIL illuminates if the TCM detects the above malfunction conditions in two consecutive drive cycles.
• PENDING CODE is available.
• FREEZE FRAME DATA is available.
• The HOLD indicator light flashes.
• The DTC is stored in the TCM memory.

POSSIBLE CAUSE

• TFT sensor malfunction
• Open circuit in wiring harness between TFT sensor and TCM terminal 1F
• Open circuit in wiring harness between TFT sensor and TCM terminal 1B
• 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 DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME PID 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 - IS CONCERN INTERMITTENT OR CONSTANT?
• Turn the ignition switch to the LOCK position.
• Turn the ignition switch to the ON position (engine off).
• Are the TCM terminal 1F voltage within 0.2-4.9 V?
Yes
Go to the intermittent concern troubleshooting procedure.
No
Go to the next step.
4
INSPECT TERMINAL COMPONENT NO.2 (8-PIN) FOR POOR CONNECTION
• Turn the ignition switch to the LOCK position.
• Inspect the terminal component No.2 (8-pin) connection.
• Disconnect the terminal component No.2 (8-pin).
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Are the connector and terminals normal?
Yes
Go to the next step.
No
Repair or replace the connector and/or terminal, then go to Step 11.
5
INSPECT TFT SENSOR CIRCUIT
• Turn the ignition switch to the ON position (engine off).
• Connect terminal component No.2 (8-pin) terminal H and G (wiring harness-side) using a jumper wire.
• Verify if the TCM terminal 1F voltage changes to 0.2 V or below.
• Does the TCM terminal voltage change?
Yes
Go to the next step.
No
Go to Step 8.
6
INSPECT COUPLER COMPONENT CONNECTOR CONNECTION FOR POOR CONNECTION
• Turn the ignition switch to the LOCK position.
• Remove the control valve body cover.
• Disconnect the coupler component connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Are the terminals normal?
Yes
Go to the next step.
No
Repair or replace the connector and/or terminal, then go to Step 11.
7
INSPECT COUPLER COMPONENT CIRCUIT FOR OPEN CIRCUIT
• Inspect for continuity between coupler component (8-pin) terminals I and J (part-side).
• Is there continuity?
Yes
Repair or replace terminal component No.2 (8-pin).
No
Replace the TFT sensor, then go to Step 11.
8
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).
• Are the terminals normal?
Yes
Go to the next step.
No
Repair the terminals, then go to Step 11.
9
INSPECT WIRING HARNESS FOR OPEN CIRCUIT
• Disconnect the terminal component No.2 (8-pin)
• Connect the TCM connector.
• Turn the ignition switch to the ON position (engine off).
• Inspect the voltage at terminal component No.2 (8-pin) terminal G (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 11.
10
INSPECT TERMINAL COMPONENT NO.2 (8-PIN) CIRCUIT FOR OPEN CIRCUIT
• Turn the ignition switch to the LOCK position.
• Inspect for continuity between terminal component No.2 (8-pin) 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.
11
VERIFY TROUBLESHOOTING OF DTC P0713 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the TCM memory using the WDS or equivalent.
• Drive the vehicle for 150 s or more.
• Is the same DTC present?
Yes
Replace the TCM, then go to the next step.
No
Go to the next step.
12
VERIFY AFTER REPAIR PROCEDURE
• Perform the "After Repair Procedure".
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
