how to work mass air flow sensor

Mass airflow sensor basics | MAF sensor working

Definition: The sensor used to determine mass flow rate of the air is known as mass airflow sensor. The air mass details are required in order to balance correct amount of fuel mass to the vehicle engine. As air density depends on temperature, altitude as well as application of forced induction, MAF sensors are more useful and more appropriate to determine quantity of air intake in each of the ...

How Do Mass Air Flow Sensors Work? - Servoflo

Mass air flow sensors are used to monitor and control air flow rate from the oxygen machine. How it Works. Mass air flow sensors contain a thermal sensor and a heating source. Once gas begins flowing through the heating source, it transports the heat away, which changes the temperature difference between the heating source and the thermal sensor. This change is used to determine the energy required to maintain the sensor …

How to Troubleshoot a Mass Airflow Sensor - AxleAddict

13/01/2020· Question: My mass air flow sensor on an 88 Camaro reads 5-volt reference between signal and ground while running and unplugged, on the ECM side, at idle. Shouldn't the mass air flow sensor dictate the voltage going out to the ECM? While plugged in, there is erratic non-detectable voltage, on/off, on/off. My ground tests good, and I have excellent battery voltage on ECM side of the …
