1.6.2.2 Result of the Diagnosis

The Cylinder Imbalance Detection monitors the final and the predicted cylinder individual air-fuel-ratio (AFR) adaptation values. These adaptation values are a measure for the uncorrected air fuel ratio of each single cylinder compared to the average AFR of all cylinders of one bank. An error is set as soon as the absolute value of the cylinder individual adaptation value of one arbitrary cylinder exceeds a specific limit.
