Circuit/System Description
WARNING: This page is about a different variant/trim than selected.
| 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 |
|---|---|
| B74 Manifold Absolute Pressure Sensor | The sensor is a capacitive pressure transducer. Electronics in the sensor convert pressure into an analog voltage signal. The sensor measures the pressure in the intake manifold between the throttle valve and the intake valves. |
| 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 sensor measures the pressure in the intake manifold. The signal is used to determine the engine load.
