id050206801400

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. (See INTERMITTENT CONCERN TROUBLESHOOTING [L8, LF, L3].)
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. (See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [JA5AX-EL].)
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. (See TCM REMOVAL/INSTALLATION [JA5AX-EL].)
No | Go to next step.
12 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [JA5AX-EL].) • Is there any DTC present? | Yes | Go to applicable DTC inspection.
No | Troubleshooting completed.
