    Abstract: Systems and methods for correcting mass airflow sensor drift include an operation conditions module to interpret a base calibration function, a MAF sensor input value, and a current operating condition. A MAF correction module determines an expected MAF value in response to the current operating condition and a predetermined operating condition. The MAF correction module will also determine an adjusted MAF value in response to the expected MAF value, the base calibration function, and the MAF sensor input value. A MAF reporting module is structured to provide the adjusted MAF value.

    Abstract: Systems and methods are disclosed for compensating a mass airflow (MAF) sensor reading to account for the bleeding or diversion of intake airflow for compressor operation in determining fresh air flow into an engine. The engine is downstream from the compressor diversion.
