Abstract
Various methods and systems are provided for diagnosing a condition of a component in an exhaust gas recirculation system. In one example, a method includes selectively routing exhaust from a first subset of engine cylinders to an exhaust passage via a first valve and to an intake passage via a second valve and determining a respective condition of each of the first valve and second valve based on a first exhaust pressure of the first subset of engine cylinders and a second exhaust pressure of a second subset of engine cylinders.
