DTC P0713

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

DETECTION CONDITION

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

POSSIBLE CAUSE

• TFT sensor malfunction.
• Open circuit between TFT sensor and TCM terminal 1F
• Open circuit 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 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 and/or on-line repair information 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 - IS CONCERN INTERMITTENT OR CONSTANT?
• Turn ignition key to OFF.
• Connect voltmeter to TCM terminal 1F
• Turn ignition key to ON (engine OFF).
• Are TCM terminal voltage within 0.2-4.9 V?
Yes
Go to intermittent concern troubleshooting procedure.
No
Go to next step.
4
INSPECT TERMINAL COMPONENT NO.2 (8-PIN) FOR POOR CONNECTION
• Turn ignition key to OFF.
• Inspect terminal component No.2 (8-pin) connection.
• Disconnect terminal component No.2 (8-pin).
• Check for poor connection (damaged, pulled-out terminals, corrosion etc.).
• Are connector and terminals okay?
Yes
Go to next step.
No
Repair or replace connector and/or terminal, then go to Step 11.
5
INSPECT TFT SENSOR CIRCUIT
• Connect voltmeter to TCM terminal 1F.
• Turn ignition key to ON (engine OFF).
• Connect between terminal component No.2 (8-pin) terminal H and G (harness-side) using jumper wire.
• Verify if TCM terminal voltage changes to 0.2 V or below.
• Does TCM terminal voltage change?
Yes
Go to next step.
No
Go to Step 8.
6
INSPECT COUPLER COMPONENT CONNECTOR CONNECTION FOR POOR CONNECTION
• Turn ignition key to OFF.
• Remove control valve body cover.
• Disconnect coupler component connector.
• Check for poor connection (damaged, pulled-out terminals, corrosion, etc.).
• Are terminals okay?
Yes
Go to next step.
No
Repair or replace connector and/or terminal, then go to Step 11.
7
INSPECT COUPLER COMPONENT CIRCUIT FOR OPEN CIRCUIT
• Check 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 TFT sensor, 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.).
• Are terminals okay?
Yes
Go to next step.
No
Repair terminals, then go to Step 11.
9
INSPECT HARNESS FOR OPEN CIRCUIT
• Disconnect terminal component No.2 (8-pin)
• Connect the TCM connector.
• Turn ignition key to ON (engine OFF).
• Inspect voltage at terminal component No.2 (8-pin) terminal G (harness-side).
• Is voltage 5 V?
Yes
Go to next step.
No
Repair or replace harness, then go to Step 11.
10
INSPECT TERMINAL COMPONENT NO.2 (8-PIN) CIRCUIT FOR OPEN CIRCUIT
• Turn ignition key to OFF.
• Check continuity between terminal component No.2 (8-pin) terminal H (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 for 150 s or more.
• 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".
• Is there any DTC present?
Yes
Go to applicable DTC inspection.
No
Troubleshooting completed.
