Introduction • • A high-pressure fuel rail for each cylinder bank (2 total) Numerous high-pressure pipes from the high-pressure pump to the rails, and rails to the injectors Engine protection mode Ford diesel engines are equipped with engine protection and emission control systems. These systems monitor critical temperatures and pressures, and modify engine operation accordingly. These modified engine performance characteristics are normal. If these modified engine performance characteristics persist for an extended period and either the service engine soon or powertrain malfunction,reduced power, electronic throttle control light is illuminated, have the system checked by an authorized dealer. Service engine soon The fuel and water separator removes both water and impurities from the fuel. The engine mounted filter filters finer impurities from the diesel fuel. The engine-mounted fuel filter and the fuel and water separator filter should be changed at the recommended service interval or when indicated by the information display LOW FUEL PRESSURE message. Refer to the scheduled maintenance information in this supplement for more information. The fuel and water separator should be drained at regular intervals (recommended at every oil change) or when indicated by the information display and water in fuel indicator light. See Fuel Quality (page 15). Proper fuel filter maintenance and prompt water draining when the water in fuel light illuminates is essential to prevent injection equipment damage. Ignoring the water in fuel light can cause your vehicle to go into a reduced power mode. A frame-mounted electric fuel pump located inside the fuel and water separator draws fuel from the fuel tank to provide pressurized fuel to the engine. The fuel pump contains a pressure relief valve for overpressure protection in the event of restricted flow. The fuel injection system is controlled through the powertrain control module. Powertrain malfunction, reduced power, electronic throttle control Lubrication system It is important to change the engine oil at the recommended service intervals to maintain oil viscosity. Extending the oil and filter change interval beyond the recommended interval can negatively affect engine performance, fuel economy and engine life. See Engine Oil Check (page 43).
