Abstract
Systems and methods for evaluating operation of a differential pressure sensor are disclosed. In one example, the differential pressure sensor may be configured to sense a pressure drop across a particulate filter. An operational assessment of the differential pressure sensor may determine whether or not a reference port of the differential pressure may be temporarily clogged.
