| Component | Description |
|---|---|
| B13 Transmission Fluid Temperature Sensor | The temperature sensor is a negative temperature coefficient thermistor, a resistor which changes based on temperature. B13 is part of the component: Q8 Control Solenoid Valve Assembly |
| K71 Transmission Control Module | 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. K71 is part of the component:Q8 Control Solenoid Valve Assembly |
The sensor is an input to the control module K71.The input signal is used to determine the temperature of the fluid: Transmission
No external circuit diagnosis is involved.
