Air Flow Meter/Sensor: Description and Operation
Mass Air Flow Sensor (205)
Main task
Sends frequency-modulated information on air mass flow to the control module and serves as main sensor for fuel injection.
Type
The mass air flow sensor contains two PTC resistors (RH) connected in parallel that are located in the air stream and are electrically heated to 220
degrees C above air temperature.
Air temperature is measured with a special PTC resistor (RS).
