Abstract
Method to detect a faulty operating condition during a cylinder cutoff of an internal combustion engine with at least two cylinder banks, wherein the internal combustion engine comprises in each case a separate mechanism to determine the Lambda value of the combustion for each cylinder bank. When the Lambda values of the cylinder banks change in opposite directions, a faulty cylinder cutoff is suggested.
