| 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 |
|---|---|
| B105 Supercharger Air Inlet Pressure Sensor | The sensor measures the pressures between the throttle body and the supercharger. When the engine is off the sensor pressure should be the same as the barometric pressure. When the engine is at idle speed the sensor pressure should be the same as manifold absolute pressure. Under wide-open throttle conditions the pressure will increase considerably. |
| K20 Engine Control Module | The control module contains a microprocessor used to process input data to control outputs. The control module controls a series of actuators to ensure optimal engine performance. The control module does this by reading values from a variety of sensors, interprets the data and adjusts the engine actuators accordingly. |
