Circuit/System Description
WARNING: This page is about a different variant/trim than selected.
For an overview of the component/system, refer to: Throttle Actuator Control (TAC) System 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 ground. |
| Low Reference | Grounded through the control module. |
| Component | Description |
|---|---|
| B107 Accelerator Pedal Position Sensor | The component contains 2 potentiometer(s) that varies its resistance proportionally with the position of the component/system: Accelerator Pedal 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 accelerator pedal position sensors, which are not serviceable. When the accelerator pedal is pressed, the voltages of both sensors goes up. This redundant design enables the ECM to detect if the 2 signals indicate the same accelerator pedal position.
