Fuel Metering Valve
WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
The fuel metering valve is located on the top of the HP fuel pump. The valve is sealed to the HP fuel pump body with an O-ring seal and secured with two screws.
The fuel metering valve is a variable position solenoid-operated valve that is controlled by the PCM with a PWM signal.
The fuel metering valve controls the quantity of fuel delivered to the HP fuel pump from the fuel pump module in the fuel tank. The valve returns unwanted fuel back to the fuel tank. This avoids unused fuel being pressurized by the HP stage of the pump, only to be returned back to return system by the fuel rail pressure control valve, wasting energy and heating the fuel.
