Accessory Drive Belt Tensioner - Dynamic
Check
The accessory drive belt tensioner may be checked
dynamically as follows:
1. With the engine running, observe the accessory drive belt tensioner movement. The accessory
drive belt tensioner should move (respond)
when the engine is accelerated rapidly or when
the A/C clutch cycles ON and OFF (the degree
of movement can be up to 4 mm). If the
accessory drive belt tensioner movement is not
constant without engine acceleration or A/C
clutch cycling, a pulley or shaft is possibly bent,
out of round, or the damping mechanism inside
the accessory drive belt tensioner may be
damaged. INSTALL a new accessory drive belt
tensioner as necessary.

System Operation
Smart Start
The PCM enables the starting process when a key
providing a valid code is read via the PATS. This
code is then verified in the GEM and compared
with the saved code. If this code is recognized as
correct, synchronization with other modules is
carried out. After successful synchronization, the
engine is cleared to start in the PCM. The PCM
connects earth to the starter relay, which then
connects power to the starter solenoid. As soon
as the engine reaches a certain speed, the PCM
disconnects the starter relay and so turns off the
starter. This protects the starter.
If the engine does not turn or turns only slowly, the
starting process is aborted by the PCM.
The starter is notactivated if:
• the engine is running (i.e. the engine speed is above a particular value),
• the PATS does not permit the engine to be started,
• the clutch pedal is not operated (vehicles with manual transmission),
• the gear selector level is not set to P or N (vehicles with automatic transmission),
• the brake pedal is not operated (vehicles with automatic transmission).
Emergency starting function
If the keyless vehicle system is unable to recognize
the passive key, the vehicle can be started via the
emergency starting function. In this case, there is a passive key mount on the
steering wheel. A PATS transmission/reception
unit is attached to this.
To start the engine, the passive key must be
inserted into the passive key mount. The Start/Stop
button can then be used to turn on the ignition and
start the engine as normal. To deactivate the
PATS, a transponder is fitted in the passive key,
which is read by the transmission/reception unit.

Powertrain Control Module (PCM)
E65160
The PCM communicates with all engine sensors
and the other modules. Communication of the PCM
with the other modules and the system diagnostics
takes place via the CAN (controller area network)
data bus.
The following functions are regulated or controlled
by the PCM:
• Fuel supply to the engine including lambdacontrol
• Ignition setting including knock control
• Idle speed control
• Control of optimum valve timing via the camshaft adjustment for intake and exhaust camshafts
• The refrigerant compressor is controlled by the air conditioning clutch relay and the delivery of
the refrigerant compressor is controlled by a
PWM (pulse width modulation) signal.
• Control of EVAP purge valve
• Boost pressure control
• Control of the cooling fan
• Charging system (Smart Charge)
• Starting system (Smart Start)
If the PCM is isolated from the vehicle electrical
system or the battery is disconnected, the throttle
control unit mustbe initialized.
The PCM is fitted in the engine compartment in the
air filter housing. On right hand drive vehicles a
protective metal plate is also installed to prevent
the plug connector from being pulled off, or make
it harder to pull off, in case of theft. The protective
plate is secured with a shear bolt. The shear bolt
needs to be drilled out in order to remove the
protective plate.
Knock Sensor
E96986
Two KSs are fitted. They are on the cylinder block,
one close to the 2nd cylinder and one close to the
4th cylinder.
When fitting, adhere strictly to the specified
tightening torque, otherwise the KS will not work
properly.
If the signal from one or both KS is implausible or
absent, knock control is deactivated. The PCM
switches to an ignition map that is further away
from the knock limit. As a result, engine damage
caused by combustion knock is avoided. If a fault
occurs, a fault code is stored in the error memory
of the PCM.
Camshaft Position (CMP) Sensor
E89993
If one or both CMP sensors fail, a fault is saved in
the error memory of the PCM and the camshaft
adjustment and knock control are deactivated.

Crankshaft Position (CKP) sensor
E89994
The CKP sensor can be checked during starting
by measuring the resistance and/or voltage with
the oscilloscope.
The engine cannot work without the CKP signal.
A limp-home mode is therefore not possible. The
engine is switched off or the engine will not start
and a fault is stored in the error memory of the
PCM.
Camshaft adjuster solenoid valve
E96870
For work on the camshaft adjuster solenoids,
extreme cleanliness must be ensured as even
slight impurities can result in failure. The camshaft
adjustment solenoids for the intake and exhaust
camshafts differ only in terms of the position of the
fastening point by which they are fixed to the
cylinder head cover.
If a fault is detected in the camshaft adjustment
solenoids, the solenoids are no longer actuated.
Manifold absolute pressure and
temperature sensor
E96146
During installation of the MAPT sensor, correct
sealing must be ensured to ensure that no
infiltrated air can penetrate into the intake manifold
from outside.
If the MAP (manifold absolute pressure) sensor
fails, the PCM operates with a substitute value.
Accelerator pedal position (APP)
sensor
E74146
The APP (accelerator pedal position) sensor
comprises two separate sensors.

FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL

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.

After disconnecting the battery or replacing the
throttle control unit or the PCM, initialization is
necessary. • engine off
• Accelerator pedal not pressed
• Battery voltage 11 ... 14 V
• Ignition key in ON position
• Wait approximately 30 seconds until initialization
is complete.
Engine Coolant Temperature (ECT)
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.

System Operation
The engine is controlled by the PCM. For this
purpose, the PCM uses information from the
sensors, sender units and switches. In addition,
the PCM receives information from other control
modules via the CAN data bus. All the information
is processed in the PCM and is used to control or
regulate the different actuators.
These are:
• the throttle control unit,
• the fuel injectors, • the camshaft adjustment,
• the boost control solenoid valve
• and the ignition coils.
Some values are sent via the CAN databus to other
systems.
The following functions are regulated or controlled
by the PCM:

• Starting process
• Engine running– Fuel supply to the engine including lambdacontrol
– Ignition setting including knock control
– Idle speed control
– Boost pressure control
– Valve timing via the camshaft adjuster for the intake and exhaust camshafts (including
internal exhaust gas recirculation)
• Refrigerant compressor (activation, deactivation and delivery)
• EVAP purge valve
• Charging system
Fuel is supplied to the engine via a sequential
multi-point injection system. Ignition is performed
by a distributor-less ignition system with one
ignition coil unit for each cylinder.
The PCM optimizes engine power and emissions
at all times by processing the sensor signals and
information received via the CAN databus and
using these for open or closed loop control of the
different variables.
The PCM contains part of the PATS (passive
anti-theft system).
The PCM is supplied with battery voltage via a fuse
in the BJB (battery junction box). This power supply
is needed to ensure that saved data is not lost
when the engine is switched off.
For other power supply requirements, the PCM
switches on a relay in the BJB which is responsible
for supplying power to the PCM and to some
sensors and actuators. Each of these are protected
by fuses in the BJB.
To guarantee optimum engine running at all times,
the PCM has several adaptive (self-learning)
functions. These adapt the output signals to
changing circumstances, such as wear or system
faults.
In some cases a faulty signal is replaced with a
substitute value or limited. A substitute value can
be calculated from other signals or it can be
predefined by the PCM. The substitute value allows
the vehicle to keep on running without the emission
values changing unduly. Depending on the signal
failure, the PCM operates in emergency mode. In
this mode, the engine power and/or the engine
speed is reduced to prevent further damage.
Depending on the faulty signal, a fault code is
stored in the error memory of the PCM. These can be read out using IDS (Integrated Diagnostic
System) via the DLC.
The PCM processes and evaluates the signals
from the sensors. The following sensors send
signals to the PCM:
• CMP sensors
• CKP sensor
• MAF sensor
•KS
• ECT sensor
• TP sensor
• APP sensor
• Broadband HO2S
• Catalyst monitor sensor
• MAPT sensor
• Air conditioning (A/C) pressure sensor
• Alternator
• Fuel temperature and fuel pressure sensor
• Engine oil level, temperature and quality sensor
• Outside air temperature sensor
The following components receive signals from the
PCM:
• Powertrain Control Module relay
• A/C clutch relay
• injectors
• Direct ignition coils
• Cooling fan module
• Throttle control unit
• Camshaft adjuster solenoid valve
• Starter Relay
• EVAP purge valve
