Circuit/System Description
WARNING: This page is about a different variant/trim than selected.
For an overview of the component/system, refer to Electronic Component Description
| Circuit | Description |
|---|---|
| 5 V Reference | Regulated voltage supplied by the control module. |
| Signal | The control module input circuit has an internal resistance connected to 5 V. |
| Low Reference | Grounded through the control module. |
| Component | Description |
|---|---|
| B12B Transmission Fluid Pressure Sensor | The sensor is a capacitive pressure transducer. Electronics in the sensor convert pressure into an analog voltage signal. |
| 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. |
B12BA Transmission Fluid Pressure Sensor 1 = Primary Pulley Pressure
B12BB Transmission Fluid Pressure Sensor 2 = Secondary Pulley Pressure
