Maintenance
To align the throttle body, use the diagnostic software.
For the engine to work properly, adjust the throttle body
so that the idling regime control works at “mid-range”.
To do this, after finding the correct alignment, proceed
as follows:
If the “lead correction” channel is NEGATIVE, close the
bypass valves to take air out, keeping it aligned until
the “Lead correction” setting goes to work within a
range of -4° to +4°.
If the “Lead correction” channel is POSITIVE, open the
bypass valves to add air, keeping it aligned until the
“Lead correction” setting goes to work within a range of
-4° to +4°.
When the adjustment is over, turn off the vehicle,
remove the connection pipe and replace the four pro-
tective plugs.
Not required adjustment of carbon oxide rate (CO).
CO ADJUSTMENT IS NOT REQUIRED.
The system can correct its (stoichiometric) carburetion
through the Lambda probe control. This does not hap-
pen straightaway but depends on the Lambda probe
switching speed for a water temperature of 85 to 105 °C.
You will notice that, when the Lambda probe % con-
troller work slightly ABOVE ZERO, the ADOFFPL set-
ting WILL INCREASE and will bring the Lambda %
channel back to about 0 ±3%.
You will notice that, when the Lambda probe % con-
troller work slightly BELOW ZERO, the ADOFFPL set-
ting WILL DECREASE and will bring the Lambda %
channel back to about 0 ±3%.
