Zusammenfassung:	Methods and systems are provided for providing passive boost pressure monitoring for slow response with higher confidence. A response time of a boost pressure feedback control loop following a boost pressure deviation that is triggered by either system disturbances or operator torque demand is monitored. Slow boost behavior is correlated with boost control degradation affecting drivability and emissions.
