ON-BOARD DIAGNOSTIC [AW6A-EL, AW6AX-EL]
STEP
4 INSPECT RESISTANCE OF TFT SENSOR
CIRCUIT
• Inspect for resistance between couple
component terminals B8 and B7 (wiring
harness-side).
• Is resistance as shown below?
— ATF temperature 10°C {50°F}: 5.62— 7.31
kilohms
— ATF temperature 25°C {77°F}: 3.5 kilohms
— ATF temperature 110°C {230°F}: 0.22—
0.27 kilohms

TEMPERATURE (TFT) SENSOR
INSPECTION[AW6A-EL, AW6AX-EL].)
5 VERIFY TROUBLESHOOTING OF DTC P0711
COMPLETED
• Make sure to reconnect all the disconnected
connectors.
• Clear the DTC from the memory using the M-
MDS.
• Drive the vehicle in D range and make sure
that gears shift smoothly from 1GR to 6GR.
• Is same DTC present?
6 VERIFY AFTER REPAIR PROCEDURE
• Perform the "After Repair Procedure".
(See 05-02-4 AFTER REPAIR
PROCEDURE[AW6A-EL, AW6AX-EL].)
• Are any DTCs present?

DTC P0712[AW6A-EL, AW6AX-EL]
DTC P0712 Transaxle fluid temperature (TFT) sensor circuit malfunction (short to ground)
• If the TCM detects the following condition for 10 s or more, the TCM determines that the TFT sensor circuit
has a malfunction.
— ATF temperature 200 °C {392 °F} or more
Diagnostic support note:
• This is continuous monitor (CCM).
DETECTION
• The MIL illuminates if the TCM detects the above malfunction condition during first drive cycle.
CONDITION
• A PENDING CODE is not available.
• FREEZE FRAME DATA is available.
• The AT warning light illuminates.
• The DTC is stored in the TCM memory.
• TFT sensor malfunction
• Short to ground in wiring harness between TFT sensor and TCM terminal B8
POSSIBLE
• Short to ground in wiring harness between TFT sensor and TCM terminal B7
CAUSE
• Damaged connector TCM
• TCM malfunction
