the DFCM filter should be changed at the recommended service interval
or when indicated by the message centerLOW FUEL PRESSURE
message. Refer to thescheduled maintenance informationin this
supplement for more information.
The DFCM should be drained at regular intervals or when indicated by
the message center message and water in fuel indicator light. SeeFuel
filter/water separatorin theMaintenance and Specificationschapter.
The fuel injection system is controlled through the powertrain control
module (PCM).
Fuel is drawn from the fuel tank by a frame-mounted electric fuel pump
located inside the DFCM and provides pressurized fuel to the engine.
The fuel pump contains a pressure relief valve for overpressure
protection in the event of restricted flow.
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 features are
intended to modify engine performance characteristics. If these modified
engine performance characteristics persist for an extended period or the
service engine soon
or powertrain malfunction/reduced
power/electronic throttle control light
is illuminated, seek service
from your authorized dealer.
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. Refer toEngine oilin the
Maintenance and Specificationschapter.
Fast start glow plug system
The diesel engine glow system consists of:
•eight glow plugs (one per cylinder)
•the glow plug control module (GPCM)
•engine coolant temperature (ECT) sensor
•barometric pressure (BARO) sensor
•environmental temperature sensor
