| Circuit | Description |
|---|---|
| Control - Terminal 1 | The output circuit is switched to ground to activate the component. The output is PWM controlled. |
| Control - Terminal 2 | The output circuit is switched to 12 V to activate the component. The output is PWM controlled. |
| Component | Description |
|---|---|
| Fuel Pressure Regulator@G18 Fuel Pump - High Pressure | The fuel pressure regulator is a solenoid valve that restricts the flow of fuel to the high pressure fuel pump and thereby controls the pressure the pump can produce.The fuel pressure regulator maintains fuel pressure in the fuel feed pipe and the fuel rail in order to prevent long cranking times. |
| 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 fuel pressure regulator is a part of the high pressure fuel pump.The fuel pressure regulator is the solenoid valve that controls the pressure in the fuel rail.
