Abstract:
Systems and methods for controlling and diagnosing air flow through a compressor without recirculating air flow through the compressor are presented. In one example, a position of an air flow control device located within a compressor housing is adjusted responsive to a request to diagnose flow through the compressor. The diagnostic may be performed while maintaining engine torque and speed.
