Example:
Assuming a leaner fuel-air mixture is produced. This has the following consequence, that the O sensor voltage drops and the ME-SFI [ME] 2 control 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-SFI [ME] control unit.
