Pic. 2.42. Air flow sensor: 1 - platinum «heated thread»; 2 - thermistor; 3 - air flow; 4 - intake air temperature sensor
The plug-in type air mass sensor allows a portion of the intake air to flow through the sensing element area. Directly measures intake air mass and flow rate, measurement accuracy is improved and air flow resistance is reduced. The air mass sensor has a built-in intake air temperature sensor.
