Case 1: Mass air flow meter rationality (high voltage) 

MAF METER VOLTAGE

MAF air flow meter voltage More than 2.2 V (varies with throttle position)

Case 2: Mass air flow meter rationality (low voltage) 

MAF METER VOLTAGE

MAF air flow meter voltage Less than 2 V (varies with throttle position)
