* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and
Inspection/Programming and Relearning) following all transmission related repairs.
* Before replacing the TCM, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection (See:
Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component Tests and General
Diagnostics/6T70/6T75 - Automatic Transmission/Control Solenoid Valve and Transmission Control Module Assembly Inspection).
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

Circuit/System Description
The automatic transmission fluid temperature sensor provides transmission fluid temperature to the transmission control module (TCM). The TCM
supplies a 5 V reference signal to the sensor. The automatic transmission fluid temperature sensor is a variable resistor that measures the
temperature of the transmission fluid and is a thermistor, or a resistor that changes value when the temperature changes. The sensor has a negative
temperature coefficient. This means that as the temperature increases the resistance decreases and vice versa. The TCM will compare the
temperature difference between the engine coolant temperature sensor and the automatic transmission fluid temperature sensor to determine if the
temperatures are within an acceptable operating range of each other. This fault is handled inside the TCM and no external circuits are involved.
Conditions for Running the DTC
P0711
* The ignition voltage is 10.2-15.5 V.
* The engine speed is greater than 400 RPM for 2 s.
* TCM communication is normal.
* DTCs P0712, P0713 are not set.
