id0502a1801200

DTC P0711 | Transaxle fluid temperature (TFT) sensor circuit range/performance (stuck)
--- | ---
DETECTION CONDITION | • When all conditions below are satisfied. - When 180 s have passed after engine is started, vehicle is driven for 150 s or more at vehicle speed between 25 - 59 km/h {15 - 36 mph}, then 60 km/h {37 mph} or more for 100 s 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 flashes. • DTC is stored in the PCM memory.
POSSIBLE CAUSE | • TFT sensor malfunction • Connector corrosion • 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 | INSPECT TFT SENSOR VOLTAGE • 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. • Record terminal 1AU voltage. • Start engine. • Drive vehicle at 60 km/h {37 mph} or above for 430 s or more. • Record terminal 1AU voltage again. • Is variation in voltage 0.06V or above? | Yes | Go to Step 5.
No | Go to next step.
4 | INSPECT TERMINAL CONDITION • Turn the ignition switch off. • Disconnect ATX connector. • Inspect terminals for corrosion. • Are terminals normal? | Yes | Go to next step.
No | Repair or replace terminals, then go to next step.
5 | VERIFY TROUBLESHOOTING OF DTC P0711 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from memory using WDS or equivalent. • Decrease ATF temperature to 20 °C {68 °F} or below. • Start engine and wait for 180 s or more. • Drive vehicle at a vehicle speed between 25 - 59 km/h {15 - 36 mph} for 150 s or more. • Drive vehicle at vehicle speed 60 km/h {37 mph} or above for 100 s or more. • Is pending code present? | Yes | Replace PCM, then go to next step. (See PCM REMOVAL/INSTALLATION.)
No | Go to next step.
6 | 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.
