Abstract

Various systems and methods are described for an engine system with an exhaust gas recirculation system. In one example method, a correction for a gas constituent sensor is determined based on output from the gas constituent sensor and output from a pressure sensor over a range of boost pressure. The gas constituent sensor output is adjusted based on the correction, and an amount of exhaust gas recirculation is adjusted based on the adjusted gas constituent sensor output.
