Fuel Charging and Controls
WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The fuel charging and control system consists of the:
- throttle body.
- fuel injectors.
- fuel charging wiring.
- fuel injection supply manifold.
- fuel rail pressure (FPR) sensor.
- fuel pump relay.
The fuel charging and control system is:
- a sequential, multiport fuel injection (SFI) system.
- pulse width modulated.
- mass air flow controlled.
The fuel rail:
- delivers fuel to the individual fuel injectors.
- receives fuel from the fuel supply tube.
The throttle body:
- controls air supply to the upper intake manifold by positioning the throttle plate.
- is not adjustable.
- cannot be cleaned.
The fuel injectors:
- are electrically operated by the powertrain control module (PCM).
- each have an internal solenoid that opens a needle valve to inject fuel into the lower intake manifold.
- atomize the fuel as the fuel is delivered.
- are deposit-resistant.
The fuel pump relay engages the fuel pump when energized by the powertrain control module.
The fuel charging wiring is a single harness that also includes electrical connectors for monitoring all engine functions.
