Air Flow Meter/Sensor: Description and Operation
Mixture Control Unit
Throttle Valve Location
The mixture control unit consists of the air-flow sensor, CIS-E fuel distributor and the air guide housing.
Incoming air deflects the plate of the air-flow sensor which actuates the plunger within the CIS-E fuel distributor. The position of the plunger determines
the quantity of fuel required. The air guide housing directs the measured air through the throttle valve housing and to the intake system.
