Abstract
Systems and methods for detecting and compensating miswiring of oxygen sensors of a cylinder bank of an engine are disclosed. In one example, fuel control parameters are monitored to determine whether or not the fuel control parameters diverge to fuel control thresholds. If so, a controller may switch which cylinder's equivalence ratios are adjusted in response to output of a particular oxygen sensor.
