Component	Description
B13 Automatic Transmission Fluid Temperature Sensor	The temperature sensor is a negative temperature coefficient thermistor, a resistor which changes based on temperature. Low temperature produces a high resistance: 46 kΩ @ −40°C (−40°F) High temperature produces a low resistance: 60 Ω @ 150°C (302°F)
K71 Transmission Control Module	The control module contains a microprocessor used to process input data to control outputs. The control module receives information from a variety of sensors, switches and serial data information from other control modules. This information is used to control a combination of solenoid valves to obtain the correct line pressure, gear ratio and torque converter clutch operation.

The sensor is an input to the control module K71. The input signal is used to determine the temperature of the fluid: Transmission Conditions for Running the DTC P0711 Condition 1 DTC P0712, P0713, P2818 = Not set DTCs related to the following system/component = Not Set B14A Automatic Transmission Output Speed Sensor B26 Crankshaft Position Sensor B34 Engine Coolant Temperature Sensor B65 Manifold Absolute Pressure and Intake Air Temperature Sensor B75 Mass Airflow Sensor B107 Accelerator Pedal Position Sensor Q17 Fuel Injector Engine Misfire Fuel Trim System Accelerator Pedal Position Sensor = Greater than 4% Battery Voltage = Greater than 9 V Engine Coolant Temperature = −40 to 150°C (−40 to 302°F) Engine Speed = Greater than 500 RPM Engine Torque = Greater than 50 Nm (37 lb ft) Ignition and Start Signal = 9 to 32 V Ignition and Start Switch Signal = On Transmission Fluid Temperature = −40 to 150°C (−40 to 302°F) Vehicle Speed = Greater than 10 km/h (7 MPH) Frequency the DTC runs = Continuously — After the running conditions are met P0711 Condition 2, 3 & P0712, P0713 Battery Voltage = Greater than 9 V Ignition and Start Signal = 9 to 32 V Ignition and Start Switch Signal = On { P0711 Condition 3 } Transmission Fluid Temperature = −40 to 150°C (−40 to 302°F) Frequency the DTC runs = Continuously — After the running conditions are met Conditions for Setting the DTC P0711 Transmission Fluid Temperature = The temperature does not change within a predetermined time.
