Circuit/System Description
WARNING: This page is about a different car, the 2019 Buick Cascada, 2018 Buick Cascada, and 2017 Buick Cascada. However, it is still accessible from the selected car via links, so may be relevant.
| Circuit | Description |
|---|---|
| 5 V Reference | Regulated voltage supplied by the control module. |
| Signal | The control module input circuit has an internal resistance connected to ground. |
| Low Reference | Grounded through the control module. |
| Component | Description |
|---|---|
| B22 Brake Pedal Position Sensor | The input voltage varies depending on the position of the sensor. |
| K20 Engine Control Module | 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. |
The pedal assembly contains 2 potentiometer-type brake pedal position sensors. When the pedal is pressed, the voltage of one sensor goes up and the voltage of the other sensor goes down.
