Typical example
The fuel manifold (2) stores high-pressure fuel from
the fuel injection pump. The high-pressure fuel will
flow to the injectors.
The fuel pressure sensor (1) measures the fuel
pressure in the fuel manifold (3).
The pressure relief valve (3) will prevent the fuel
pressure from getting too high.
The fuel pressure sensor must be replaced with the
fuel manifold (rail). The pressure relief valve can be
serviced as a separate component.

Electronic Control System

Introduction
The engine is designed for electronic control. The
engine has an Electronic Control Module (ECM), a
fuel injection pump and electronic unit injectors. All of
these items are electronically controlled. There are
also a number of engine sensors. The engine is
equipped with an electronically controlled wastegate
system for the turbocharger. The ECM controls the
engine operating parameters through the software
within the ECM and the inputs from the various
sensors. The software contains parameters that
control the engine operation. The parameters include
all of the operating maps and customer-selected
parameters.

The electronic control system has the following
components:
• ECM
• Pressure sensor
• Temperature sensors
• Crankshaft speed/timing sensor
• Camshaft speed/timing sensor
• The suction control valve for the fuel injection
pump
• Wastegate solenoid
• Electronic unit injectors
• Soot sensors (if equipped)
• Valve for the NOx Reduction System (NRS)
