Air Flow Meter/Sensor: Description and Operation
GF07.07-P-6000CY Component Description For The Hot Film Mass Air Flow Sensor
- up to model year 08
Location
Component Identification
The hot film mass air flow sensor is located behind the variable intake manifold between the air filter housing and the throttle valve positioner (M16/6).
Task
The hot film MAF sensor detects the air mass sent to the engine and the intake air temperature and sends an appropriate voltage signal to the ME-SFI
[ME] control unit (N3/10).
Design
Component Identification
The intake air temperature is also detected by one further temperature resistance.
The electronics and the housing have undergone a number of modifications (please note part number.).
Function
Electronics in the hot film mass air flow sensor regulate via a changeable voltage the temperature of the heating resistor (RH) in such a way, that its
temperature lies 160 °C above the intake air temperature detected by the temperature resistor (RL).
