METHOD AND SYSTEMS FOR EXHAUST GAS RECIRCULATION SYSTEM DIAGNOSIS

Various methods and systems are provided for diagnosing a condition of a component in an exhaust gas recirculation system (160). In one example, a method includes selectively routing exhaust from a first subset of engine cylinders (107) to an exhaust passage (116) via a first valve (164) and to an intake passage (114) via a second valve (170) and determining a respective condition of each of the first valve (164) and second valve (170) based on a first exhaust pressure of the first subset of engine cylinders (107) and a second exhaust pressure of a second subset of engine cylinders (105).
