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. (See INTERMITTENT CONCERN TROUBLESHOOTING [L8, LF, L3].)
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. (See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [FS5A-EL].)
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. (See TCM REMOVAL/INSTALLATION [FS5A-EL].)
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.
No | DTC troubleshooting completed.
