Abstract

Systems and methods are provided for diagnosing cylinders in an engine. In one example, the method may include while receiving first feedback from a vibration sensor coupled to a first cylinder of the engine, perturbing the first cylinder during engine operation. Responsive to the first feedback indicating a first vibration level difference greater than or equal to a first threshold difference, a first indication of a first degradation condition of the first cylinder may be set, and thereafter the engine may be operated based on whether or not the first indication was set.
