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.

Knowing and Understanding Customer
Concerns
Knowing and understanding customer concerns is
necessary in order to perform diagnosis.
First of all, ask the customer under which operating
conditions the problem occurs. If possible, try to
reproduce the concern by road testing the vehicle
with the customer.
You should be familiar with the following operating
conditions:
• Engine operating state
– Cold, warm-up phase, or at operatingtemperature
• Ambient temperature – Below 0 °C (32 °F), 0 to 20 °C (32 to 68 °F),or above 20 °C (68 °F)
• Road conditions – Good, poor, or off-road
• Vehicle load status – Unloaded, loaded, or fully loaded
• Transaxle status in manual mode – Upshift, downshift, overrun or acceleration
Testing Possible Causes of Transmission
Control Faults
Before performing a symptom-based diagnosis,
first carry out checks to eliminate various other
potential causes of the fault.
These situations include:
• Battery state of charge
• Defective fuses • Loose or corroded cables or electrical
connectors
• Ground connections to the transmission
• Retrofitted add-on units which are not approved by Ford, such as air conditioning, car telephone,
cruise control
• Unapproved tire sizes
• Incorrect tire size programmed with IDS (Integrated Diagnostic System)
• Engine tuning
IDS Diagnosis
NOTE: Customer concerns relating to the transaxle
can also be caused by engine-related faults.
The transmission control system of the AW55 is
closely linked to the engine management system.
Faults in the engine management system may
affect the transmission control system.
Before repairing the transaxle, it should be ensured
that the fault is not caused by the engine
management system or other non-transaxle
components.
The diagnosis can be performed on the AW55 with
the aid of von IDS.
visual inspection
A thorough visual inspection of the transaxle is
necessary for successful diagnosis.
A visual inspection is made of the following
components:
• Connectors and plug connections
• Ease of operation of the selector lever

Transmission Control
Depending on the input signals, the TCM mounted
on the transmission actuates the solenoid valves
in the valve body. The TCM calculates and stores
adaptive data, fault codes and values for diagnosis.
The TR sensor is integrated in the TCM.

The TR sensor
E125819
The TR sensor and the TCM form one unit. This
unit is located at the top of the transmission casing,
on the gear linkage.
Function
The TR sensor has three separate functions:
• Transmit a signal to the TCM about the selectedtransmission range.
• To transmit the signal to switch on the reversing lamps to the GEM when the selector lever is in
the 'R' position.
• To transmit the start enable signal to the PCM when the selector lever is in the 'P' or 'N'
position.
The TR sensor contains a permanent magnet and
a linear Hall detector. It produces a signal voltage
between 0 and 5 V. This signal voltage
corresponds to the selector lever position currently
chosen.
Voltage values for the different gears:
• P approximately 0.65 V
• R approximately 1.64 V
• N approximately 2.12 V
• D approximately 2.49 V
Consequences of signal failure
If the TR sensor fails, the MIL is activated and the
vehicle can be driven in emergency mode 4. The
vehicle can no longer be started for safety reasons
after the ignition is switched off because the TCM
does not detect the current transmission range.
If a shift solenoid valve fails, the MIL is activated
and the vehicle can be driven in the appropriate
emergency mode.

NOTE: From the start of series production, the
transfer box will be subject to a "Black Box Phase"
and will therefore not be repaired.
To realise the all-wheel drive, a transfer box has
been flange-mounted to the manual transaxle. The
transfer box is designed as an angular gear to
transfer the torque from the transaxle to the rear
axle. The hollow shaft of the transfer box is inserted
in a tooth on the gear case. From the hollow shaft,
torque is transferred to the driveshaft through the
output shaft/output flange via crown gear and
differential pinion gear.

Fluorescent Dye Leak Detection
General EquipmentUV Leak Detector
1. Refer to: Air Conditioning (A/C) System Health
and Safety Precautions (100-00 General
Information, Description and Operation).
2. NOTE: Some vehicles may have signs of
refrigerant oil at the spring lock couplers. The
cause of this may be a procedure used in
production before installation of the fittings in
order to assist their assembly. When a spring
lock coupler is suspected of leaking, always
wipe the fitting clean and verify the leak with
R-134a Automatic Calibration Halogen Leak
Detector.
NOTE: The exact location of leaks can be
pinpointed by the bright yellow - green glow of
the tracer dye. Since more than one leak can
exist, always inspect each component.
• Locate the leaks. Check all components, fittings and lines of the A/C system for leaks.
General Equipment: UV Leak Detector
3. After the leak is found and rectified, remove any
traces of dye with a general purpose solvent.
4. Check the repair by operating the system for
some minutes and inspecting with the UV lamp
again.
