DTC P0713 [JA5A-EL]

BME050218901209

DTC P0713 | Transaxle fluid temperature (TFT) sensor circuit malfunction (open circuit)
--- | ---
DETECTION CONDITION | • If the vehicle speed is 20 km/h {12.4 mph} or greater, and a signal from the TFT sensor is 2.4 V or above for 300 s or more, the TCM determines that there is a malfunction. Diagnostic support note: • This is a continuous monitor (CCM). • The MIL illuminates if the TCM detects the above malfunction conditions in two consecutive drive cycles.
• PENDING CODE is available.
• FREEZE FRAME DATA is available.
• The HOLD indicator light flashes.
• The DTC is stored in the TCM memory.
POSSIBLE CAUSE | • TFT sensor malfunction • Open circuit in wiring harness between TFT sensor and TCM terminal 1F • Open circuit in wiring harness 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 DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME PID 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 LOCK position. • Turn the ignition switch to the ON position (engine off). • Are the TCM terminal 1F voltage within 0.2-4.9 V? | Yes | Go to the intermittent concern troubleshooting procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING [AJ].)
No | Go to the next step.
4 | INSPECT TERMINAL COMPONENT NO.2 (8-PIN) FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Inspect the terminal component No.2 (8-pin) connection. • Disconnect the terminal component No.2 (8-pin). • 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 11.
5 | INSPECT TFT SENSOR CIRCUIT • Turn the ignition switch to the ON position (engine off). • Connect terminal component No.2 (8-pin) terminal H and G (wiring harness-side) using a jumper wire. • Verify if the TCM terminal 1F voltage changes to 0.2 V or below.
• Does the TCM terminal voltage change?
Yes
Go to the next step.
No | Go to Step 8.
6 | INSPECT COUPLER COMPONENT CONNECTOR CONNECTION FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Remove the control valve body cover. • Disconnect the coupler component connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Are the terminals normal?
Yes
Go to the next step.
No | Repair or replace the connector and/or terminal, then go to Step 11.
7 | INSPECT COUPLER COMPONENT CIRCUIT FOR OPEN CIRCUIT • Inspect for 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 the TFT sensor, then go to Step 11. (See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [JA5A-EL].)
8 | 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). • Are the terminals normal? | Yes | Go to the next step.
No | Repair the terminals, then go to Step 11.
9 | INSPECT WIRING HARNESS FOR OPEN CIRCUIT • Disconnect the terminal component No.2 (8-pin) • Connect the TCM connector. • Turn the ignition switch to the ON position (engine off). • Inspect the voltage at terminal component No.2 (8-pin) terminal G (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 11.
10 | INSPECT TERMINAL COMPONENT NO.2 (8-PIN) CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch to the LOCK position. • Inspect for continuity between terminal component No.2 (8-pin) 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.
11 | 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 [JA5A-EL].)
No | Go to the next step.
12 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [JA5A-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [JA5A-EL].)
No | DTC troubleshooting completed.
