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.
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.
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.
No
Go to next step.
11

VERIFY AFTER REPAIR PROCEDURE

• Perform "After Repair Procedure".
• Are any DTCs present?
Yes
Go to applicable DTC inspection.
No
Troubleshooting completed.
