OIL SENSOR
DESCRIPTION
Oil level, oil temperature and oil quality are
detected by means of an oil sensor located in the oil
pan. The sensor which operates on the capacitance
principle features an integrated electronic circuit
which analyzes the three signals. the signals are con-
stantly relayed to the ECM and over the CAN bus to
the instrument cluster by means of PWM signal.
OPERATION
Oil quality is detected for indicating the need-
based oil change interval. The oil quality is detected
on the basis of the capacitance of the engine oil
(dielectrics, does not conduct electricity), this being
as much as six times greater in case of poor quality.
Oil level and oil quality are separate of each other.
The information is first of all compensated in the
ECM before being transmitted over the CAN bus.
Faults at the oil sensor are detected by the ECM
and entered into fault memory. The voltage for the
oil sensor (approx.5V) is supplied by the ECM.

FUEL RAIL PRESSURE SEN-
SOR
DESCRIPTION
The fuel rail pressure sensor is attached to the
front of the fuel rail. The sensor supplies the current
fuel rail pressure to the ECM.
OPERATION
Non-constant fuel system pressure influences the
position of a diaphragm inside the sensor. This
results in a variation in the electrical resistance. The
fuel rail pressure sensor supplies the appropriate
voltage signal to the ECM.
REMOVAL
(1) Disconnect the negative battery cable.
(2) Disconnect the sensor wiring harness connector
(Fig. 4).
NOTE: Place a shop towel underneath the sensor to
capture any fuel spillage.
(3) Unscrew the sensor and discard the seal.

FUEL QUANTITY CONTROL
VA LV E
DESCRIPTION
The fuel quantity control valve mounts to front of
the high pressure pump and is controlled by the
ECM. The quantity control valve assists in maintain-
ing proper fuel quantity injected under all operating
conditions. Fuel tank heat protection is also provided
by the quantity control valve. The valve meters the
exact amount of fuel to prevent excess heated fuel
from returning to the tank.
OPERATION
The ECM monitors the fuel system and measures
for pressure vibrations. The ECM will then send a
pulse width signal to the quantity control valve to
regulate the amount of fuel to the high pressure
pump plunger and barrel assemblies. The valve then
adjusts the injection correction quantity for each
individual cylinder in line with the firing order, there
by eliminating the pressure resonance in the fuel rail
and improving each independent injectors operation.
The fuel quantity valve also interrupts the fuel sup-
ply to the high pressure pump plunger and barrel
assemblies when the engine is switched off.
The ECM detects the operating state which exists
at the engine by means of the sensors. In order to
adapt the quantity injected, either the rail pressure
can be adjusted by way of the pressure regulator
valve and the quantity control valve, or the actuationtime of the solenoid valves in the fuel injectors can
be extended or shortened.
Fuel quantity control is performed under the fol-
lowing operating conditions:
²Approximately 30 seconds after the engine has
started
²Fuel temperature > 20ÉC (68ÉF)
²Engine not in deceleration mode
REMOVAL
(1) Disconnect the negative battery cable.
(2) Disconnect the control valve wiring harness
connector (Fig. 18).
(3) Remove the valve fasteners and remove the
control valve (Fig. 18).
INSTALLATION
(1) Clean sealing surfaces.
(2) Install new seal on sensor.
(3) Position the control valve on to the high pres-
sure pump and install fasteners (Fig. 19).
(4) Connect wiring harness connector to control
valve (Fig. 19).
(5) Connect negative battery cable.
(6) Start the engine, allow to run, turn engine off
and inspect for leaks (Refer to 14 - FUEL SYSTEM/
FUEL INJECTION - WARNING).

CRANKSHAFT POSITION SEN-
SOR
DESCRIPTION
The crankshaft position sensor is located opposite
the teeth on the flywheel and uses a non contact
method to record the position of the crankshaft. The
leading edges of each tooth on the flywheel generate
a positive signal in the position sensor, while the
trailing edges generate a negative signal. When the
crankshaft is rotating, an alternating voltage is pro-
duced as a result.
The period of the signal is the time required by the
crankshaft to turn through the gap between two fly-
wheel teeth. The clearance between the crankshaft
position sensor and the teeth of the flywheel is fixed
by the installation.
Two teeth on the flywheel are missing. The result-
ing signal gap is used by the ECM to detect the TDC
position of cylinder number one.
OPERATION
The clearance between the crankshaft position sen-
sor and the flywheel are fixed by the installation
position. Two teeth on the flywheel are missing. The
resulting gap is used by the ECM to detect DTC of
cylinder number one. The crankshaft position is cal-
culated to an accuracy of a fraction of a degree so
that the start and end of injection can occur at
exactly the right moment. The engine speed signal is
also processed by the ECM from the crankshaft sen-
sor. This signal is then transferred to other control
modules over the CAN bus.
If the crankshaft position sensor fails, the ECM
will stop triggering the injectors, the engine will
stall, the engine warning light may or may not illu-
minate, but the engine will not restart.
REMOVAL
(1) Disconnect the negative battery cable.
(2) Unplug the crankshaft wiring harness connec-
tor.
(3) Remove the crankshaft sensor retaining bolt
and remove sensor (Fig. 9).
INSTALLATION
(1) Position the crankshaft position sensor into the
access hole and install retaining bolt.
(2) Tighten the retaining bolt to 80 lbs. in. (9 N´m)
(Fig. 9).
(3) Connect crankshaft position sensor wiring har-
ness connector (Fig. 9).
(4) Connect negative battery cable.
FUEL INJECTOR
DESCRIPTION
FUEL INJECTOR
There are individual fuel injectors for all five cyl-
inders. Each injector nozzle has seven holes. The fuel
injectors are used to spray fuel into the combustion
chamber. Each injector has a six digit alphanumeric
code on the injector top which must be entered into
to ECM using the DRBIIIt(Fig. 10). Specific moving
parts inside the injector are graphite coated to assist
with the lubrication process.

FUEL PRESSURE SENSOR
DESCRIPTION
The fuel rail pressure sensor measures the current
fuel rail pressure and supplies an appropriate voltage
signal to the ECM. The non-constant fuel system
pressure influences the position of the internal dia-
phragm. This results in a variation in the electrical
resistance which is analyzed by the ECM.
OPERATION
The fuel rail pressure sensor measures the current
fuel rail pressure and sends a voltage signal to the
ECM. The ECM then actuates the fuel rail pressure
control valve until the desired rail pressure is
achieved.
REMOVAL
(1) (Refer to 14 - FUEL SYSTEM/FUEL INJEC-
TION - WARNING) Disconnect the negative battery
cable.
(2) Remove the mixing housing.
(3) Unplug the sensor (Fig. 14).
(4) Counter-hold the threaded connection at the
fuel rail and unscrew the sensor (Fig. 14).

injector return fuel hose to the banjo bolt fitting in
the left rear corner of the cover. Failure to do so
may pinch or damage the hose causing fuel leakage
or a driveability concern.
(5) Connect negative battery cable.
FUEL PRESSURE SOLENOID
DESCRIPTION
The fuel pressure solenoid is attached to the rear
of the fuel rail. A sealing metal disc seals the valve to
the rail. The seal is not serviceable and looses it's
sealing properties upon removal of the solenoid.
Therefore, the solenoid must be replaced when ever
it is removed from the rail. The solenoid controls and
maintains the rail pressure constant along with a
control current transmitted by the engine control
module (ECM) (Fig. 15).
OPERATION
High pressure which is present in the fuel rail
flows to the ball seat of the pressure solenoid (Fig.
16). The specified pressure required by the system is
built up in the rail by the fuel pressure solenoid
building up a magnetic force which corresponds to
this specific pressure by means of a control current
from the electronic control module (ECM) (Fig. 16).
This magnetic force equals a certain outlet cross sec-
tion at the ball seat of the valve. The rail pressure is
altered as a result of the quantity of fuel which flows
off (Fig. 16). The current fuel pressure is signaled by
the fuel rail pressure sensor to the engine control
module (ECM). The controlled fuel flows back along
the return fuel line, into the tank.
In a de-energized state, the fuel pressure solenoid
is closed as the spring force presses the ball into the
ball seat (Fig. 16). When driving, the fuel pressure
solenoid is constantly open (Fig. 16). When engine is
started, the fuel pressure solenoid is held closed by
magnetic force (Fig. 16). When driving, the pressure
of the fluid counteracts the magnetic force of the coil
and the slight spring force (Fig. 16).
