System Operation
Instrument Cluster
The instrument cluster contains analog displays
as well as warning and control lamps for displaying
the system status; in addiiton, there is an LCD
indicator field for driver information.
The instrument cluster receives the following
signals from the PCM via the high speed CAN
(controller area network) Bus (HS-CAN):
• Vehicle speed – The PCM receives the necessary signalsfrom the ABS (anti-lock brake system) wheel
sensors from the ABS control unit on the
HS-CAN.
• Engine Coolant Temperature
• Engine oil pressure.
• Engine speed
The instrument cluster receives the following
signals from the GEM via the medium speed CAN
Bus (MS-CAN):
• Ambient temperature
• Brake fluid level
• Handbrake control
• Door latch control
• Liftgate latch control
• High beam control
• Headlamp flasher control
• Direction indicator control
The fuel level signal is sent by the two fuel level
sensors in the fuel pumps in the semitrailer tank,
which is wired to the instrument cluster. The
sensors are connected in series, and the total
resistance is determined from the two individual resistors. The instrument cluster converts the raw
fuel level signal into a damped fuel level value.
The odometer shows the total distance travelled
by the vehicle and is based on the same signal as
is processed for the daily mileage counter. The
value is recorded by the instrument cluster and
stored in a protected EEPROM (Electronically
Erasable Programmable Read Only Memory) area.
This area is a memory protected against
manipulation. If the instrument cluster detects an
error in this memory area, e.g. through damage,
the driver is notified with the "Odometer error"
message.
Message center
The message center is operated using the left-hand
switch on the steering column.
The SET/RESET button is activated to select a
submenu and change the settings. If signal tones
have been activated, a short acoustic signal will
sound each time a button is pressed.
By turning the rotary switch, the different menu
displays can be scrolled through or a setting
selected.
In this display, the navigation system can also
display direction and distance information.
In addition, safety and warning messages can be
displayed in this system, such as "Coolant
overheating", "Engine system error" or "Washer
fluid level too low". In addition to a safety message,
a general warning light (red/yellow) lights up.

Engine Cooling — 2.5L Duratec (147kW/200PS) - VI5 – Overview
Auxiliary coolant pump
An electrically operated auxiliary coolant pump is
installed on vehicles with a trailer coupling and/or
additional heating. The auxiliary coolant pump
ensures that the coolant is circulated when the
coolant pump (which is driven by the engine) is not
running.
The additional heating uses the auxiliary coolant
pump to circulate hot coolant through the heat
exchanger and the engine.
On vehicles with a trailer coupling the auxiliary
coolant pump is switched on for 6 minutes by the
PCM (powertrain control module) if the coolant
temperature exceeds 106°C when the engine is
switched off. This prevents the coolant circuit from
overheating. This could happen particularly if the
engine is switched off after towing a heavy trailer
up a steep hill before there has been sufficient time
for cooling.

Turbocharger – Overview
Turbocharger(s)
CAUTION: Do not switch off the engine
while it is running at high speed. If the
engine is switched off while it is running
at high speed, the turbocharger will
continue to run after the engine oil
pressure has already dropped to zero. This
will cause premature wear in the
turbocharger bearings.
A TC consists of an exhaust turbine located in the
exhaust gas flow, this turbine is connected to a
compressor by a shaft. The turbine is made to
rotate by the exhaust gas flow from the engine and
thus drives the compressor. The compressor
increases the pressure in the engine intake tract
so that a greater mass of air enters the cylinder
during the intake stroke.
The turbine housing of the TC is integrated into the
exhaust manifold. This construction offers
thermodynamic advantages compared with the
usual construction, the maximum exhaust
temperature is up to 1050°C.
The maximum boost pressure is 0.65 bar.
The exhaust manifold is secured to the exhaust
side of the cylinder head with 12 self-locking nuts.
The exhaust manifold gasket is a multi-layer steel
gasket and cannot be reused. In order to
compensate for the thermal expansion of the
exhaust manifold, the flange of the TC is provided
with two grooves.
The TC and the exhaust manifold are joined by a
hose clip. The hose clip must not be loosened or
removed. The TC and the exhaust manifold are
not available as separate replacement parts,
exchange is only possible as a complete unit.
The turbocharger heat shield is secured to the
exhaust manifold by four bolts. Two of the bolts
have spring washers underneath their heads.
During removal, make a note of the installation
location of the spring washers to refer to during
installation.
The recirculated air valve is built into the TC
housing and cannot be changed.
The Ford diagnostic unit can test the operation of
the wastegate control valve using actuator
diagnosis.
The boost pressure regulator is set in the factory.
Adjustments to the boost pressure regulator must never be attempted. A red colored seal is applied
to the adjustment nut of the operating rod, in order
to monitor the factory setting of the boost pressure.
The bearings of the TC are lubricated with engine
oil. The engine oil passes from the cylinder block
through the oil supply pipe to the TC. The oil is
returned to the oil pan through the oil return pipe,
The TC is cooled by the engine coolant circuit.
When installing hoses and lines, make certain that
their ends are free of oil residues and dirt.

If one of the two APP sensors fails, then only a
proportion of the engine's power will be available
when accelerating. Top speed can nevertheless
be achieved.
If both of the APP sensors fail, the engine is
regulated to a defined speed following a plausibility
check after the BPP (brake pedal position) switch
and brake light switch have been actuated once.
The vehicle can then only be accelerated to a
defined speed.
In either case, a fault is saved in the error memory
of the PCM.

sensor
E94804
The ECT (engine coolant temperature) sensor is
designed as an NTC (negative temperature
coefficient) resistor.
If the signal from the ECT sensor fails, the cooling
fan is on all the time and the A/C (air conditioning)
is turned off. When the ignition is switched on, the
value from the IAT (intake air temperature) sensor
is read. When the engine is running, the
temperature is calculated using a temperature map
stored in the PCM according to how long the
engine has been running. This substitute value is
then used as the basis for calculating the injected
fuel quantity and the ignition timing.

The acceleration of the flywheel at each power
stroke results in a change in the CKP signal.
During the power stroke, the combustion pressure
acting on the piston causes an acceleration of the
crankshaft and thus also of the flywheel. This is
apparent in the voltage curve from slightly higher
frequencies and amplitudes of the CKP signal.
Calculation of the ignition angle
Since propagation of the flame front in the air/fuel
mixture always takes the same amount of time, the
ignition of the air/fuel mixture has to take place
earlier or later depending on the engine speed.
The higher the speed, the earlier ignition must
occur. This ensures that maximum combustion
pressure is achieved immediately after Top Dead
Center and that maximum combustion pressure
acts on the piston.
When starting the engine, ignition timing is
determined by the CMP purely from the ignition
map and information on camshaft position (CKP
sensors) and crankshaft position (PCM sensor).
As soon as the engine is running, the following
data are used as a basis for calculating the ignition
angle:
• the engine speed,
• the engine load,
• the coolant temperature and
• the KS signal.
The ignition angle has a major impact on engine
operation. It affects
• engine performance
• exhaust emissions
• fuel consumption,
• combustion knock behavior and
• engine temperature.
The higher the engine load, i.e. the torque demand,
the richer the air/fuel mixture, the longer the
combustion period and the earlier the ignition. The PCM calculates engine load using the MAF
sensor signal, the throttle position and engine
speed. This is done using ignition maps that are
stored in the PCM. The ignition timing is adjusted
according to the operating condition of the engine,
for cold starting for example.

The ignition maps were calculated in a series of

behaviour, power and fuel consumption of the
engine. The ignition map is stored in the data
memory of the PCM.
By adjusting the ignition timing it is also possible
to influence the engine speed to some extent
without having to change the throttle valve position.
This has advantages for idling stabilization, as the
engine speed and hence the engine torque respond
far more quickly to a change in the ignition timing

current value is reached. The PCM then
permanently connects the heating element to earth.
The catalyst monitor sensor is used by the PCM
to measure the oxygen content in the exhaust gas
in the TWC. If all the conditions for catalyst
diagnostics are met, based on this information the
PCM can check that the TWC is working
satisfactorily. The information is also used to
improve the air/fuel mixture adjustment.
The catalyst monitor sensor is similar in function
to an HO2S. The signal transmitted by the catalyst
monitor sensor changes sharply if the oxygen
content in the exhaust gas changes. For this
reason, catalyst monitor sensors are also called
"jump lambda sensors".
Fuel tank purging
The EVAP purge valve is only actuated by the PCM
if the coolant temperature is at least 60°C.
Actuation is done ground side by means of a PWM
signal. This makes it possible to have the full range
of opening widths, from fully closed to fully open.
The PCM determines from the operating conditions
when and how wide to open the EVAP tank purge
valve. If the EVAP purge valve is opened, the
engine sucks in ambient air through the activated
charcoal in the evaporative emission canister as
a result of the vacuum in the intake manifold. In
this way the adsorbed hydrocarbons are led to the
combustion chamber of the engine.
The EVAP tank purge valve is not actuated and
system cleaning is interrupted if the engine
switches to idle and/or a closed-loop control
process is initiated.
Power (battery voltage) is supplied via the
Powertrain Control Module relay in the BJB. The
solenoid coil resistance is between 17 and 24 ohms
at 20°C.
Engine speed control
The APP sensor provides the PCM with information
about the driver's request for acceleration.
The throttle control unit receives a corresponding
input signal from the PCM. An electric motor then
moves the throttle valve shaft by means of a set
of gears. The position of the throttle is continuously
recorded by the TP sensor. Information on throttle
position is processed and monitored by the PCM.
The TP sensor comprises two potentiometers.
These work in opposite ways to each other. In one
potentiometer, the resistance increases when the
throttle is opened, in the other it decreases. Thisallows the operation of the potentiometers to be
checked. The signal from the TP sensor is
amplified in the lower range (idle to a quarter open)
by the PCM to enable more precise control of the
throttle in this range. This is necessary because
the engine is very sensitive to changes in throttle
angle in this throttle opening range.
With the throttle valve position kept constant, the
ignition angle and the injected fuel quantity are
then varied to meet the torque demands.
Depending on the operating state of the engine, a
change in the position of the throttle flap may not
be necessary when the APP sensor changes.
If a fault develops in the throttle control unit, a
standby function is executed. This standby function
allows a slight opening of the throttle flap, so that
enough air passes through to allow limited engine
operation. For this purpose, there is a throttle flap
adjustment screw on the throttle housing. The
return spring closes the throttle flap until the stop
of the toothed segment touches the stop screw. In
this way a defined throttle flap gap is formed for
limp home mode.
The stop screw has a spring loaded pin, which
holds the throttle flap open for limp home mode.
In normal operating mode, this spring loaded pin
is pushed in by the force of the electric motor when
the throttle flap must be closed past the limp home
position (e.g. for idle speed control or overrun
shutoff).
Oil monitoring
The engine does not have an oil pressure
switch.
The oil level and oil quality are calculated.
Calculating the engine oil level
The oil level is determined by continuous
measurement of the capacitance (i.e. the ability to
store an electrical charge) between the two
capacitive elements of the engine oil
level/temperature/quality sensor. The different oil
levels cause the capacitance between the elements
to change. The data are recorded by the PCM and
converted into an oil level value. Temporary
fluctuations in oil level are automatically filtered out
by the PCM.
Calculating oil quality
The PCM calculates the oil quality from the oil level
measurement and the oil temperature measured
by the sensor, plus the engine speed and the
average fuel consumption. The driver is informed
about when an oil change is due.
