The MAF sensor works on the ‘hot-film principle’.
The MAF sensor is powered via the Powertrain
Control Module relay in the BJB. The MAF sensor
is connected to ground via the PCM.
The MAF sensor sits in a molded part which
protrudes into the center of the air cleaner's outlet
pipe. From this position, it measures the air mass
drawn in by the engine.
The air mass aspirated by the engine is determined
on the basis of the cooling effect of the intake air
via a hot-film element in the MAF sensor. The
greater the aspirated air mass, the greater the
cooling effect and the lower the electrical resistance
of the hot-film element. The electronics in the MAF
sensor process this resistance value and send a

voltage signal to the PCM corresponding to the
aspirated air mass.
This analogue voltage signal is between 0.5V and
5V. Low mass of intake air produces a low voltage
signal. A high mass of intake air produces a
correspondingly high voltage signal.
The MAF sensor is also capable of detecting the
backflow of the intake air. A sensor element is
heated electrically on the integrated chip and then
cooled by the air flowing through. The regulating
switch supplies the heating current in such a way
that it attains a constant excess temperature in
comparison to the intake air. The mass air flow and
the direction of flow can be derived from this
heating current (given in the form of a signal
voltage). Below a certain voltage value there is a
return flow. The direction is flow is registered by
two sensors pointing in different directions. The
measurement does not require a great deal of
software processing effort, even with a strongly
pulsating mass air flow.MAPT
E96146
The MAPT sensor combines two sensors in one
housing. These are the MAP sensor and the IAT
sensor. They take the form of a piezoelectric
resistor and an NTC resistor.
The MAP sensor receives a reference voltage of
5V from the PCM. The output signal from the MAP
sensor element is an analog voltage signal which
changes proportionately to the prevailing pressure
in the intake manifold.
The IAT sensor records the temperature of the
intake air downstream of the intercooler.

Refrigerant Oil Adding
CAUTION: Collect the refrigerant oil in a
clean measuring cylinder.
1. NOTE: This step only needs to be carried out
when removing the A/C compressor.
NOTE: Rotate the compressor shaft at least 6
to 8 turns when draining the refrigerant oil.
Drain the refrigerant oil from the defective A/C
compressor and dispose of it.
2. CAUTIONS:
The refrigerant oil top-up quantity must
not exceed the refrigerant oil fill
quantity.
If other A/C components are being
renewed in addition to the A/C
compressor, there is no need to top up
with additional refrigerant oil, apart from
filling the compressor.
Top up with the calculated quantity of new
refrigerant oil. See:Specifications(412-00
Heating, Ventilation, Air-Conditioning - General
information, Specifications).

Fault Memory Interrogation without
diagnostics unit - vehicles with
automatic temperature control
NOTE:On vehicles equipped with a DVD
navigation system with touchscreen, the fault
memory can only be interrogated using the Ford
diagnostic tool.
The climate control and heating system features
a on-board diagnosis function which can detect
and store both current permanent faults as well as
intermittent faults which have occurred during
normal operation of the vehicle. It is also possible
to read out these faults via the display on the
control panel of the climate control system. To read
out the fault memory, the ignition key must be
turned to the "ON" position and the battery voltage
must be between 9 V and 16 V.
To activate the on-board diagnosis at the control
panel for the climate control system, PRESS the
"OFF" and "FOOTWELL" buttons simultaneously
for exactly 2 seconds, then PRESS "AUTO" within
1.5 seconds. The on-board diagnosis which then
starts lasts a few seconds. An animated display
appears in the display of the control panel for the
climate control system during this time. Any faults
found are displayed on both displays of the control
panel for the climate control system in the form of
trouble codes.
To read out saved errors at the control panel for
the climate control system, PRESS the "OFF" and
"FOOTWELL" buttons simultaneously for exactly
2 seconds, then PRESS "HEAD AREA" within 1.5
seconds. Any stored faults are shown on the
display of the control panel for the climate control
system and should be noted for safety reasons.
By PRESSING the "DEFROST" button, the fault
memory is cleared and diagnosis mode is ended.
To end the diagnostic mode without clearing the
DTCs, PRESS any other operating button on the
control panel for the climate control system.
To read out the software version at the control
panel for the climate control system, PRESS the
"OFF" and "FOOTWELL" buttons simultaneously
for exactly 2 seconds, then PRESS "A/C" within
1.5 seconds. The software version is shown on the
display of the control panel for the climate control
system. The output mode can be exited by
PRESSING any button on the control panel for the
climate control system.
Switch over from Celsius to Fahrenheit
The switch from Celsius to Fahrenheit is performed
on the display of the instrument cluster and is then
transmitted via the CAN bus to the module of the
two-zone air conditioning system.

permitted, the high-pressure switch turns off the
refrigerant compressor.
The compressor on-off cycle is controlled by the
dual pressure switch depending on the pressure
in the refrigerant accumulator. The dual pressure
switch turns the refrigerant compressor off
permanently if the pressure falls below a permitted
value (e.g. if there is a leak).
Component Description
Air conditioning compressor
E100826
The special feature of a compressor with variable
swash plate is that the stroke of the pistons can
be varied by means of the variable swash plate.
The swash plate is mounted on a slide rail in the
axial direction.
The piston stroke and thus the delivery rate are
determined by means of the variable obliqueness
of the swash plate.
The obliqueness of the swash plate is dependent
upon the chamber pressure and thus on the
pressure conditions at the top and bottom of the
piston. This is supported by springs in front of and
behind the swash plate.
The chamber pressure is determined by the high
and low pressure applied to the control valve and
by a calibrated orifice bore. If the low pressure is
relatively high, the control valve is opened and the
chamber pressure is reduced.
If the low pressure is relatively low, the control
valve is closed and the chamber pressure is
increased. The force due to the chamber pressure
exerted on the piston bottom, is higher than the
sum of the force due to the low pressure on the
piston top and the spring force.
Pollen filter
E97720
The fresh air flowing into the vehicle through the
air inlet housing passes through a pollen filter which
is located on the left-hand side of the climate
control housing (LHD and RHD) and removes
pollen and dust particles measuring 0.003 mm or
more.
Control assembly, climate control -
vehicles with manual temperature control
E97721
In vehicles with manual temperature control, the
heating and air conditioning are operated using
three rotary switches. The air distribution flaps are
actuated via the air distribution flap/temperature
control flap actuating unit, which is connected via
a rod to the control assembly for the climate
control. The temperature control flap is also
actuated via the air distribution flap/temperature
control flap actuating unit, which is connected via
a cable to the control assembly. In addition, the
operating switch for recirculated air mode and the
on/off switch for the air conditioning are located on
the control assembly.
