DTC P0713

BHE050201026W11

DTC P0713 | Transmission fluid temperature (TFT) sensor circuit malfunction (open circuit/short to power supply)
--- | ---
DETECTION CONDITION | • Vehicle speed is 20 km/h {12.4 mph} or more, and signal from TFT sensor is 2.4 V or more for 150 s or more. Diagnostic support note: • This is a continuous monitor (CCM). • MIL illuminates if TCM detects the above malfunction condition during the first drive cycle. • PENDING CODE is not available. • FREEZE FRAME DATA is available. • AT warning light illuminates. • DTC is stored in TCM memory.
POSSIBLE CAUSE | • TFT sensor malfunction • Open circuit in wiring harness between TFT sensor terminal D and TCM terminal 2J • Open circuit in wiring harness between TFT sensor terminal B and TCM terminal 2N • Short to power supply in wiring harness between TFT sensor terminal D and TCM terminal 2J • Short to power supply in wiring harness between TFT sensor terminal B and TCM terminal 2N • 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 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 ON position (engine off). • Inspect the voltage at TCM (wiring harness-side) terminal 2J. • Is the terminal voltage within 0.2-4.9 V? | Yes | Go to the intermittent concern troubleshooting procedure, then go to Step 13. (See INTERMITTENT CONCERN TROUBLESHOOTING.)
No | Go to the next step.
4 | INSPECT TCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • 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 13.
5 | INSPECT AT SOLENOID VALVE CONNECTOR FOR POOR CONNECTION • Disconnect the AT solenoid valve connector. • 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 13.
6 | INSPECT AT SOLENOID VALVE CONNECTOR CIRCUIT FOR OPEN CIRCUIT OR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (engine off). • Inspect the voltage at AT solenoid valve connector (wiring harness-side) terminal C. • Is the terminal voltage within 4.0-5.0 V? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to Step 13.
7 | INSPECT AT SOLENOID VALVE CONNECTOR CIRCUIT FOR SHORT TO POWER SUPPLY • Inspect the voltage at AT solenoid valve connector (wiring harness-side) terminal D. • Is the terminal voltage B+? | Yes | Repair or replace the wiring harness, then go to Step 13.
No | Go to the next step.
8 | INSPECT AT SOLENOID VALVE CONNECTOR CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch to the LOCK position. • Disconnect the TCM connector. • Inspect for continuity between the AT solenoid valve connector (wiring harness-side) terminal D and TCM (wiring harness-side) terminal 2N. • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to Step 13.
9 | INSPECT CONTROL VALVE BODY CONNECTOR FOR POOR CONNECTION • Disconnect the control valve body connector. • 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 13.
10 | INSPECT CONTROL VALVE BODY CONNECTOR CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (engine off). • Inspect the voltage at control valve body (wiring harness-side) terminals B and D. • Is the terminal voltage B+? | Yes | Repair or replace the wiring harness, then go to Step 13.
No | Go to the next step.
11 | INSPECT CONTROL VALVE BODY CONNECTOR CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch to the LOCK position. • Disconnect the control valve body connector. • Inspect for continuity between the AT solenoid valve connector (wiring harness-side) and control valve body connector (wiring harness-side). – Terminal C and terminal D – Terminal D and terminal B • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to Step 13.
12 | INSPECT TFT SENSOR • Inspect the TFT sensor. (See TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR INSPECTION.) • Is the TFT sensor normal? | Yes | Go to the next step.
No | Replace the TFT sensor, then go to the next step. (See TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION.)
13 | 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. (See TCM REMOVAL/INSTALLATION.)
No | Go to the next step.
14 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [RC4A-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [RC4A-EL].)
No | DTC troubleshooting completed.
