id0502a1801400

DTC P0713 | Transaxle fluid temperature (TFT) sensor circuit malfunction (open circuit)
--- | ---
DETECTION CONDITION | • If PCM detects either of following conditions for 150 s or more, PCM determines that TFT sensor circuit has a malfunction. - TFT sensor voltage is 4.67 V or above and vehicle speed 20 km/h {12 mph} or above. Diagnostic support note: • This is a continuous monitor (CCM). • MIL illuminates if PCM detects the above malfunction conditions during first drive cycle. • PENDING CODE is not available. • FREEZE FRAME DATA is available. • HOLD indicator light flashes. • DTC is stored in the PCM memory.
POSSIBLE CAUSE | • TFT sensor malfunction • Open circuit between TFT sensor and ATX connector terminal E • Open circuit between TFT sensor and ATX connector terminal H • Open circuit between ATX connector terminal E and PCM terminal 1AU • Open circuit between ATX connector terminal H and PCM terminal 1AN • Damaged connectors between TFT sensor and PCM • PCM 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 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 • Turn the ignition switch off. • Connect breakout box to PCM. • Turn the ignition switch to the ON position (Engine OFF). • Measure the voltage at PCM terminal 1AU. • Are voltage readings below 4.67 V? | Yes | Go to intermittent concern troubleshooting procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING.)
No | Go to next step.
4 | INSPECT ATX CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Inspect ATX connector connection. • Disconnect ATX connector. • Check for poor connection (damaged/pulled-out terminals, corrosion etc.). • Is connection normal? | Yes | Go to next step.
No | Repair or replace connector and/or terminal, then go to Step 10.
5 | INSPECT TFT SENSOR CIRCUIT • Turn the ignition switch to the ON position (Engine OFF). • Measure the voltage at PCM terminal 1AU when connect between ATX connector terminals E and H (vehicle harness-side) using jumper wire. • Verify that voltage changes to 0.06 V or below. • Does voltage change? | Yes | Go to next step.
No | Go to Step 7.
6 | INSPECT TFT SENSOR CIRCUIT FOR OPEN CIRCUIT • Check of continuity between ATX terminals (transaxle case side) E and H. • Is there continuity? | Yes | Replace TFT sensor, then go to Step 10. (See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [FN4A-EL].)
No | Repair or replace harness, then go to Step 10.
7 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect PCM connector. • Check for poor connection (damaged/pulled-out terminals, corrosion, etc.). • Is connection normal? | Yes | Go to next step.
No | Repair or replace connector and/or terminal, then go to Step 10.
8 | INSPECT HARNESS FOR OPEN CIRCUIT • Disconnect ATX connector. • Connect the PCM connector. • Turn the ignition switch to the ON position (Engine OFF). • Inspect voltage at ATX connector terminal E (vehicle harness-side). • Is voltage 5 V? | Yes | Go to next step.
No | Repair or replace harness, then go to Step 10.
9 | INSPECT ATX CONNECTOR CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Inspect continuity between ATX connector terminal H (vehicle harness-side) and body ground. • Is there continuity? | Yes | Go to next step.
No | Repair or replace harness, then go to next step.
10 | VERIFY TROUBLESHOOTING OF DTC P0713 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from memory using WDS or equivalent. • Drive vehicle under following condition for 150 s or more. - Vehicle speed (VSS PID) 20 km/h {12 mph} or above. • Is same DTC present? | Yes | Replace PCM, then go to next step. (See PCM REMOVAL/INSTALLATION.)
No | Go to next step.
11 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [FN4A-EL].) • Are any DTCs present? | Yes | Go to applicable DTC inspection.
No | Troubleshooting completed.
