    摘要: 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.
