Hello , i have a problem with my MAF. It calculates air 8kg and 1.30 volts . How much should be kg and volts? my friend told me that it should be 1.37V but not sure about kg. i have to replace it so tell me about it please

 

8kg is too low. At engine operating temperature with no load. No Ac. Usually around 12kg. Look at self adaptation factor if it's shifts it will effect the kg value but not the voltage value.
