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.

•  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 AA

•  Open circuit in wiring harness between transaxle connector (primary) terminal H and TCM terminal V

•  Damaged connectors between TFT sensor and TCM

•  TCM malfunction

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 AA • Open circuit in wiring harness between transaxle connector (primary) terminal H and TCM terminal V • 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.
1		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.
2		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 AA. • Is the voltage 4.67 V or less?	Yes	Go to the intermittent concern troubleshooting procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING[LF, L3].)
3		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.
4		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 AA 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.
5		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. (See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR INSPECTION[FS5A-EL].)
6		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.
7		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.
8		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.
9		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 M-MDS. • 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. (See TCM REMOVAL/INSTALLATION[FS5A-EL].)
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE[FS5A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection.
11		No	DTC troubleshooting completed.
