FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL

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.

CAUTION: The throttle control unit must
not be repaired or adjusted. The stop of
the throttle valve must on no account be
adjusted.
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.

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.
