ADJUSTMENT AND CALIBRATION OF THROTTLE
BODY
After connecting the diagnostic software to the central
unit, before starting the engine check the position of
the throttle valve:
2.33 degrees (min. 2.1, max 2.5).
If it does not fall within the range, use the TPS feature
to reset it, WITHOUT TOUCHING THE MECHANIC
ADJUSTING SCREW OF THE THROTTLE.
After resetting the throttle (TPS) start the engine to
warm it up.
You will see that after starting the engine the Lambda
channel (mvolt), which was next to zero, will start to
rise.
After starting the Lambda control (Lambda % range),
the Lambda (mvolt) will range between a high of 1000
mvolt and a low of 0 mvolt (minus the diagnostic soft-
ware lag). To see the range more clearly, adjust the two
graphic settings.
The above behaviour means the Lambda probe is in
working order.
Otherwise, if the Lambda (mvolt) shows a fixed value
of about 0 mvolt or 1000 mvolt, after about thirty sec-
onds, with the Lambda % controller fixed at -25% or
+25%, the system will send out a ‘Lambda probe volt-
age’ alarm.
In this case, check the electric connection between the
Lambda probe and the system or replace the Lambda
probe.
Levelling of induction manifold settings
To check this, use a mercury vacuum gauge of the type
shown in the figure. Then, level the vacuum inside the
induction manifolds.
