Example:
Assuming a leaner fuel-air mixture is produced. This has the following consequence, that the O sensor voltage drops and the ME control 2 unit
compensates for this lean drift through a matching enrichment.
This makes it possible to achieve a fuel-air mixture of approximately lambda= 1.
The reading of the lambda control factor with the STAR DIAGNOSIS moves towards +25% The more the lambda control factor moves in the direction
+25%, the leaner is the fuel-air mixture and the greater is the enrichment of the mixture on the part of the ME control unit.
