above

— Vehicle speed (VSS PID) 20 km/h {12 mph}

or above

• Is pending code present?

Yes Replace PCM, then go to next step.

(See

F–43 PCM REMOVAL/INSTALLATION

.)

No

No concern is detected. Go to next step.

10

VERIFY AFTER REPAIR PROCEDURE

• Perform “After Repair Procedure”.

(See

K–52 AFTER REPAIR PROCEDURE

.)

• Are any DTCs present?

Yes Go to applicable DTC inspection.

No

Troubleshooting completed.

DTC P0711

A6E567001030W09

Diagnostic procedure

DTC P0711

Transaxle fluid temperature (TFT) sensor circuit range/performance (stuck)

DETECTION

CONDITION

• When all conditions below are satisfied.

— When 180 seconds have passed after engine is started, vehicle is driven for 150 seconds or more at

vehicle speed between 25 – 59 km/h {15 – 36 mph}, then 60 km/h {37 mph} or more for 100 seconds
or more.

— P0712, P0713 not output.
— Variation in ATF voltage below 0.06 V.

Diagnostic support note:

• This is a continuous monitor (CCM).

• MIL illuminates if PCM detects the above malfunction condition in two consecutive drive cycles or in one

drive cycle while the DTC for the same malfunction has been stored in the PCM.

• PENDING CODE is available if PCM detects the above malfunction condition during first drive cycle.

• FREEZE FRAME DATA is available.

• HOLD indicator light does not flash.

• DTC is stored in the PCM memory.

POSSIBLE

CAUSE

• TFT sensor malfunction

• Connector corrosion

• PCM malfunction
