1. A charge forming device, comprising:
a body having a throttle bore, the throttle bore having an inlet and an outlet;
a throttle valve having a head in the throttle bore;
a fuel injector having an electrically actuated valve and an outlet port, wherein fuel flows through the outlet port when the valve is open;
a pressure sensor arranged so that the pressure sensor is communicated with the pressure in the area of the outlet port, wherein the outlet port is located between the throttle valve and the outlet of the throttle bore, and the pressure sensor is communicated with the throttle bore through a passage that has a first end open to the throttle bore between the throttle valve and the outlet of the throttle bore.
