Abstract
Systems and methods for diagnosing operation of valves that control exhaust flow through crossover pipes are described. In one example, the diagnostics may be based on output of upstream and downstream oxygen sensors. In particular, correlation between output of an upstream oxygen sensor and a downstream oxygen sensor may be indicative of a valve not being in an expected position.
