Abstract
An internal combustion engine has an intake tract having a compressor. A verification is performed as to whether at least one predefined activation condition is met. A boost pressure (PUT) downstream of the compressor is sensed or determined. An adaptation characteristic curve or adaptation characteristic map (KF_AD) is adapted as a function of a rotational speed (N) of the internal combustion engine and the boost pressure (PUT) if the at least one actuation condition is met. A gradient is determined that is representative of a gradient of the adaptation characteristic curve or adaptation map (KF_AD). From the determined gradient, conclusions are drawn with respect to a fault in the intake tract of the internal combustion engine.
