2005 FIAT DUCATO 244 D sensor

104GETTING TO KNOW YOUR VEHICLE
IMPORTANTThe airtight seal of
the cap may lead to a slight increase of
pressure in the tank. A hissing sound
when the cap is removed is therefore
quite normal.
After refuelling, screw the cap until
hearing one or more clicks, turn the
key and then remove it.. close the lid.
IMPORTANTMoreover, before
starting the engine, for the sake of
safety, check whether the refuelling
gun is properly hung onto the fuel
pump.If required, replace the
fuel cap with another gen-
uine cap to avoid affecting
the efficiency of the fuel vapour
recovery system.

PROTECTING THE
ENVIRONMENT
Protection of the environment has
been the guiding principle in the design
of the Fiat Ducato right from the start.
The result is the use of materials and
creation of devices that can reduce or
considerably curtail harmful influences
on the environment.
The devices for curtailing petrol en-
gine emissions are:
– a three-way catalytic converter;
– a lambda sensor;
– a fuel evaporation system.
The devices for curtailing diesel en-
gine emissions are:
– an oxidising catalytic converter;
– an exhaust gas recirculation system
(E.G.R.) (for certain versions).
Consequently, the Fiat Ducato is
ready to travel well ahead of the most
stringent international pollution control
standards.
Keep naked flames or light-
ed cigarettes away from
the fuel filler hole as there is a dan-
ger of fire. Do not bend too close to
the hole either so as not to breathe
in harmful vapours.

CONSTRUCTION FEATURES
DUCATO automatic gearbox is con-
trolled electronically with four for-
ward gears and reverse.
It is controlled by an electronic con-
trol unit which handles:
– the torque distributor;
– gearshifting;
– specific programmes.
The gearbox is coupled with a flow
power torque distributor with piloted
antislip device which makes it possible
to obtain demultiplication ratios.
The characteristic of this gearbox
which works without idle gear enables:
– higher compactness and weight re-
duction;
– improved output due to less fric-
tion;
– lower stress of transmission com-
ponents.GENERAL FEATURES
Electronic gearbox control makes it
possible to obtain gearshifting suited
to momentary engine characteristics
with a certain elasticity.
The electronic control unit has the
following task:
– adapting the oil pressure for
gearshifting to the engine torque;
– activating safety functions;
– defining the manual gearshifting
programme;
– system diagnostics.
For controlling these operating log-
ics the control unit uses the follow-
ing signals:
– engine rpm;
– engine temperature;
– engine torque;
– vehicle speed;
– gearbox oil temperature;– gearshift lever position;
– accelerator pedal position;
– brake pedal position.
The control unit also communicates
with the injection system electronic
control unit.
Conditions of use analysed by
the control unit
The control unit analyses each single
condition of use of the vehicle, dis-
criminating it on the basis of the sig-
nals received from the various sensors.
Analysed conditions are the follow-
ing:
– starting (position/accelerator ped-
al changing speed);
– acceleration (accelerator pedal
completely pushing down speed);
– full load (number of engine full load
kickdown signals or position mainte-
nance time);

LOOKING AFTER EMISSION
CONTROL DEVICES
The correct use of pollution control
devices not only ensures respect for
the environment but also has an effect
on the vehicle’s performance.
Keeping these devices in good con-
ditions is therefore a fundamental rule
for driving that is easy on your pock-
et and on the environment too.
The first step to take is to follow the
Service Schedule to the letter.
If your vehicle has a petrol engine
with catalytic converter use only un-
leaded petrol.
if you have trouble starting, do not
keep turning the ignition key for long
periods. Be especially careful to avoid
bump starting the vehicle by pushing,
towing or rolling downhill: these are
all manoeuvres that can damage the
catalyst.
Use an auxiliary battery for start-ups
only.If the engine begins to “loose its
smoothness” when travelling, contin-
ue your journey but reduce the de-
mands you are making on the engine
and have the vehicle seen to at a Fi-
at Dealershipas soon as you can.
When the instrument panel fuel re-
serve warning light comes on, fill up as
soon as possible. A low fuel level may
cause an uneven supply of fuel to the
engine with inevitable increase in the
temperature of the exhaust gas and se-
rious damage to the catalytic con-
verter.
Never run the engine with one or
more spark plugs disconnected, even
for testing purposes.
Do not warm up the engine by let-
ting it idle for a while before moving
off unless the outside temperature is
very low and, even in this case, only
do so for less than thirty seconds.
Do not install heat shields and do not
remove those already fitted to the cat-
alytic converter and exhaust pipe.
Do not allow anything to
be sprayed onto the cat-
alytic converter, lambda sensor and
exhaust pipe.
WARNING
Ignoring the above rules
may lead to fire.
WARNING
When functioning normal-
ly the catalytic converter
reaches high temperatures. For this
reason do not park the vehicle over
inflammable material (grass, dry
leaves, pine needles, etc.): fire haz-
ard.

216TECHNICAL SPECIFICATIONS
BRAKES
SERVICE AND EMERGENCY
BRAKES
Front: disc, floating caliper with two
operating cylinders for each wheel and
pad wear warning light.
Rear: self-centring shoes and micro-
metric mechanism for clearance take-
up.
Certain versions are fitted with rear
disc brakes with Drum in hat device
(i.e. drum on disc to block the vehicle
when parked with handbrake en-
gaged).
Cross-over hydraulic circuit control.
Four sensors ABS system with EBD.
Automatic recovery of the friction
gasket wear; versions with rear disc
brake excluded (Drum in hat ver-
sions).
Lacking ABS system brakeforce dis-
tributor acting on rear brake hydraulic
circuit according to rear axle load.HANDBRAKE
Controlled by a lever, it works me-
chanically on the rear brake shoes.
For versions with rear disc brakes,
the handbrake works on the Drum in
hat device shoes.
IMPORTANTPull the handbrake
lever only when the vehicle is at a
standstill, or when the vehicle is run-
ning, but however only in case of a
failure of the hydraulic system.
Should the handbrake be exception-
ally used when the vehicle is running,
it is suggested to keep a moderate
traction to avoid causing the rear axle
block, entailing vehicle side skidding.
TRANSMISSION
CLUTCH
Hydraulically controlled without
travel-free pedal.
MECHANICAL GEARBOX
AND DIFFERENTIAL
Five forward gears and reverse with
synchromesh for front gear engage-
ment.
Cyclical gear reduction and differen-
tial assembly incorporated in the gear-
box.
Drive transmission to the front
wheels by means of drive shafts con-
nected to the differential assembly and
the wheels with CV joints.
Water, ice or salt on road
surfaces can deposit on
brake discs, reducing braking effi-
ciency on the first braking.
