Air Flow Meter/Sensor: Description and Operation
GF07.07-P-6000V Hot Film MAF Sensor, Component Description
Location
The hot film mass air flow sensor is located behind the intake manifold between the air filter housing and the throttle valve actuator.
Task
The hot film MAF sensor detects the air mass supplied to the engine and the intake air temperature.
Design
A temperature-controlled resistor detects the air mass and an integral NTC resistor detects the intake air temperature.
The flow to the hot film sensors is even through the grid. The hot film MAF sensor has an oval housing and 4-pin (production start) or 5-pin plug
connector.
The electronics and the housing have undergone a number of modifications (please note part number).
Function
The electronic control in hot film mass air flow sensor controls the temperature of the heating resistor [R(H)] by means of a variable voltage, so that its
