DIAGNOSIS AND TESTING
Accessory Drive
lnspection and Verification
1. Verify the customer concern.
2.
Visually inspect for obvious signs of mechanical
damage.

If an obvious cause for an observed or reported
concern is found, correct the cause (if
possible)
before proceeding to the next step.
Accessory Drive Belt Concerns
A CAUTI0N:Do not lubricate the accessory
drive belt, accessory drive belt tensioner
or idler
pulley(s) as potential damage to
the accessory drive belt material
construction, accessory drive belt
tensioner damping mechanism, accessory
drive belt tensioner pulley bearing and idler
pulley(s) bearing may occur.
Cracking
Accessory drive belts are made from rubber which
hardens with time and can
develop cracks. As the
belt runs on the back of some of the pulleys, the
cracks are opened up.
Small cracks are not
considered to be a
failure of the belt. Only if the
,crack is deep enough to reach the bottom of the
grooveto expose the cord or any chunks are found
to be missing from the
belt, is the belt condition
considered to be
unacceptable.
1. Check the accessory drive belt for cracks. If the
damage exceeds the
acceptable limit, install a
new accessory drive
belt.

Chunking
Chunking describes the condition where long
lengths of rubber become detached from the ribs
of the
belt. This is considered to be a failure of the
belt.

DESCRIPTION AND OPERATION
lntake Air Distribution and Filtering - 1.4L Duratec-I 6V
I (Sigma)/l .6L Duratec-1 6V (Sigma)
lntake manifold
The 1.41 and 1.61 versions feature a revised intake
manifold. The overall length of the intake pipes has
been increased, but the pipes are of equal length
on all cylinders. This has resulted in increased
torque in the lower engine speed range and a
reduction in noise levels.
I 1 I Mounting for the throttle valve unit I
FIT-MAP sensor I
The mounting for the electronic throttle valve is
located inside the intake manifold between the
intake pipes of cylinders 1 and 2. The T-MAP
sensor, which is used on both the 1.41 and 1.61
versions, is situated next to the throttle valve unit.

DIAGNOSIS AND TESTING

vehicles with diesel engine)

sensors. It will detect deviations in airlfuel ratios
(AFR) and sensor faults.
The
H02S will cause emission increase when its
response time increases too much. To diagnose
a sensor a period is measured and the number of
leanlrich transitions are counted. The sum of valid
periods is then calculated. To avoid
non-representative measurements, the period is
valid only if the
H02S has been below a low
threshold and above a high threshold between 2
consecutive leanlrich transitions.
A failure is
declared when the sum of the measured periods
exceeds the sum of the corresponding limit (held
within the PCM) and the MIL is illuminated.
Catalytic Converter Efficiency Monitor (All except
vehicles with diesel engine)
The efficiency of a catalytic converter is measured
by its ability to store and later release oxygen to
convert harmful gases. The efficiency is reduced
if the converter becomes contaminated as it ages,
and at high gas flow rates, because the exhaust
gas does not remain in the converter long enough
to complete the conversion process. switches
over or until the end of a delay. If this
delay expires or the sensor does not switch, the
sensor is treated as failed.
Combustion Noise Monitor (Vehicles with common
rail fuel injection)
In diesel variants, the Combustion Noise Monitor
is used to trim the fuel injection pulse lengths. Each
fuel injector has an associated set of correction
data that is determined during a production end of
line test. The Combustion Noise Monitor is used
to determine how the fuel injector characteristic
changes from this initial calibration over the life of
the fuel injector.
EGR Monitor (Vehicles with diesel engine)
The functionality of the EGR system is checked by
comparing either the MAP sensor output or EGR
valve lift potentiometer output (depending upon
application) with expected values.
Diagnostic Requirements
Vehicles equipped with EOBD, can be diagnosed
using the WDS. In order for the EOBD system to
be invoked, a number of criteria must be met. After
any repair, which could affect emissions, a trip must
be carried out on the vehicle, to make sure that
engine management system operates correctly.
