For an overview of the component/system, refer to: Fuel System Description
| Component | Description |
|---|---|
| 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. |
| Q18 Fuel Pressure Regulator | A solenoid valve is an electro-mechanically operated valve. The valve is controlled by an electric current through the solenoid. |
Q18A Fuel Pressure Regulator 1 & Q18C Fuel Pressure Regulator 3@G18 Fuel Pump - High Pressure
The fuel pressure regulator is a solenoid valve that controls the pressure in the fuel rail by restricting the flow of fuel from the high pressure pump.
Q18B Fuel Pressure Regulator 2@Fuel Rail
The fuel pressure regulator is a solenoid valve that controls the pressure in the fuel rail by restricting fuel returning to the fuel tank.
