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 ...

P0101 Code: Mass or Volume Air Flow ‘A’ Circuit Range ...

· One of the key sensors in this operation is the MAF sensor. The mass airflow (MAF) sensor is a device that is mounted on the air intake. Its job is to measure the density and, therefore, the volume of filtered air that is drawn into the engine. When the PCM perceives the sensor or its circuit is malfunctioning, OBD-II code P0101 is triggered.

Hot Film Mass 5 (HFM5) Air Flow Sensors - Autologic

To do this, hot film mass air flow sensors measure a small portion of the air entering the engine. The sensor takes into account positive and negative intake pulses caused by intake and exhaust valves opening and closing. Intake air temperature or ambient pressure changes have no effect on air mass measurement. HFM5 sensor housing and measuring tube are designed to accommodate engine …

Air Mass Sensors · Technipedia · Motorservice

The complete air mass sensor consists of a flow passage (tube), in which the intake air flows past the sensor unit itself. NOTE: Depending on application and vehicle, the air mass sensor is available as a single plug-in module, or fully integrated min a plastic tube. Both versions – with or without tube – are referred to as air mass sensors. Older models have a hot-wire sensor element. Any ...
