STEP

INSPECTION

ACTION

DTC P0713

Transaxle fluid temperature (TFT) sensor circuit malfunction (short to power/open circuit)

DETECTION

CONDITION

• If the TCM detects the following condition for 1 s or more, the TCM determines that the TFT sensor circuit

has a malfunction.
— Engine warmed-up

— ATF temperature less than –43

°C {–45.4 °F}

Diagnostic support note:

• This is continuous monitor (CCM).

• The MIL illuminates if the TCM detects the above malfunction condition during first drive cycle.

• A PENDING CODE is not available.

• FREEZE FRAME DATA is available.

• The AT warning light illuminates.

• The DTC is stored in the TCM memory.

POSSIBLE

CAUSE

• TFT sensor malfunction

• Open circuit in wiring harness between TFT sensor and TCM terminal B8

• Open circuit in wiring harness between TFT sensor and TCM terminal B7

• Short to power in wiring harness between TFT sensor and TCM terminal B8

• Short to power in wiring harness between TFT sensor and TCM terminal B7

• Damaged connector TCM
