• 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.
• TFT sensor malfunction
POSSIBLE
• Connector corrosion
CAUSE
• PCM malfunction
Diagnostic procedure
STEP
1 VERIFY FREEZE FRAME DATA HAS BEEN
RECORDED
• Has FREEZE FRAME PID DATA been
recorded?
2 VERIFY RELATED REPAIR INFORMATION
AVAILABILITY
• Check for related Service Bulletins availability.
• Is any related repair information available?
3 INSPECT TFT SENSOR VOLTAGE
• Turn ignition key to OFF.
• Connect breakout box to PCM.
• Turn ignition key to ON (engine OFF).
• Measure the voltage at PCM terminal 3D.
• Record terminal 3D voltage.
• Start engine.
• Drive vehicle at 60 km/h {37 mph} or above
for 430 seconds or more.
• Record terminal 3D voltage again.
• Is variation in voltage 0.06V or above?
4 INSPECT TERMINAL CONDITION
• Turn ignition key to OFF.
• Disconnect ATX connector.
• Inspect terminals for corrosion.
• Are terminals okay?
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 seconds or
more.
• Drive vehicle at a vehicle speed between 25 –
59 km/h {15 – 36 mph} for 150 seconds or
more.
• Drive vehicle at vehicle speed 60 km/h {37
mph} or above for 100 seconds or more.
• Is pending code present?
6 VERIFY AFTER REPAIR PROCEDURE
• Perform "After Repair Procedure".
