303101 B-9 Engine - 2.OL Duratec-HE (M14) 303-01 B-9
DESCRIPTION AND OPERATION
The complete engine is made of cast aluminum
which, when combined with the plastic intake
manifold, gives a very light unit.
2.OL Duratec-HE (M14) engine
Emission standard
N0TE:Due to the fine tolerance in the bearing
clearances and bearing shells, no service
operations whatsoever are permitted on the crank
assembly. In the event of damage, the complete
cylinder block and crank assembly must be
changed. European
Emissions Standard Stage
IV (Stage II I, depending
on country)
Further design features include a ladder frame
incorporating the main bearing caps which support
the crankshaft in the cylinder block, and the
deep-drawn side walls of the cylinder block which
reduce engine vibration.
The camshafts are driven by a pinned link chain
which runs very quietly and is also
maintenance-free.

DIAGNOSIS AND TESTING
RPM - engine speed
i DSRPM - desired engine speed
The IAT sensor output is useful if the engine being
tested is cold or after an over-night cold soak. The
ECT sensor or CHT sensor and the IAT sensor
should either indicate the same value or be within
1 to 2 degrees Celsius of each other.
The ECT sensor output is important to display as
it indicates the engine warm-up and opening
temperature for the thermostat. It will initially
indicate a slightly higher reading just before the
thermostat opens and then drops back before
settling to a near flat line output (see graphic
below).
Item Description
I A I Thermostat opens I
B Thermostat settles into a cyclic open and
I I closure pattern
A CAUTI0N:lf the ECT sensor output reaches
the
120°C default line under normal cooling
system pressure, internal damage may be
caused to the engine and a diagnostic
trouble code (DTC) will be set in the PCM.
The test should be stopped and the cause
located and corrected. If the cooling
system does not pressurize, the coolant
will boil at
100°C which may also damage
the engine. CARRY OUT the Coolant
Expansion Tank Cap Pressure Test
Component Test in this section.
If the WDS only allows the ECT sensor to be
displayed in volts, refer to the following table for
corresponding Celsius values:
Volts
OCelsius
The CHT sensor output is useful to examine the
cylinder head temperature rise during the warm-up
cycle and later during the normal light throttle cruise
test. This sensor output may vary between vehicles
with manual transmission and vehicles with
automatic transmission and should be used for
reference only.
Volts
0.78
0.60
0.46
0.35
0.27
The
LOAD display is used for reference as it is
necessary to maintain a stable load line during the
test. It is necessary to carry out the test under
normal light throttle cruise driving conditions and
average loads, typically
40% to 70% of the load
value.
OCelsius

90
100
11 0
120
The VSS output is used for reference but can help
to identify misfires and sensors which fail during
the warm-up cycle.
The RPM display indicates the engine speed and can be compared with the DSRPM.
The DSRPM is the desired or calculated idle speed
which the PCM commands the engine to reach. If
the thermostat opens too early (before the correct
opening temperature has been reached), the
engine will not reach this value.
When using the WDS in data logger mode, the
signals recorded should remain within the
DEFAULT values set by the WDS.
3m AWARNING:M~~~ sure that the WDS is
placed in the vehicle so that it does not
interfere with the safe operation of the
vehicle. Do not place the WDS in the
deployment path of any air bag. Failure to
follow these instructions may result in personal injury.
N0TE:The road test is best carried out with the
aid of another technician in the vehicle to enable
the vehicle to be driven safely while the sensor
outputs are monitored within datalogger. If there
is only one technician available, the WDS can be
set up (using the
recordlcapture mode camera
icon) before leaving the workshop to record a
16
km (1 0 mile) test.

REFER to:
RoadlRoller Testing (1 00-00 General
Information, Description and Operation).
4. Drive the vehicle at a constant throttle opening
and set speed until the ECT value settles into
a shallow rise and fall signal, close to a straight
line. This indicates that the thermostat is
functioning correctly.
N0TE:Some thermostats indicate the
temperature(s) in Celsius and Fahrenheit.
The graphic below shows the location and an
example of the opening temperature
(88OC) and

risequite quickly with smooth progression.
If
the ECT signal appears unstable or erratic, the
ECT sensor, electrical connector and wiring
harness to the PCM need to be visually inspected
for damage, chafing or water ingress.
The temperature should rise to approximately
90°C
for a thermostat that has an 88OC value. The signal
value will then fall as cooler coolant enters the
engine.
If the ECT value fails to maintain a constant value
and falls back to lower figures, typically between
60°C (140°F) and 70°C (1 50°F), the thermostat
and its sealing function within the thermostat
housing must be checked.
5. INSTALL a new thermostat.
