Air Flow Sensor Circuit:
Volume Air Flow Sensor Operation:
PURPOSE
The Air Flow Sensor (AFS) is a "Karman Vortex" type which measures the volume of air entering the intake manifold to provide the Engine Control Module (ECM) with precise intake volume information.
OPERATION
- The volume air flow sensor located in the air cleaner converts the engine intake air volume into a pulse signal with a frequency proportional to the air volume and inputs it to the engine control module which then computes the fuel injection rate etc. based on the input signal.
- The volume air flow sensor power is supplied from the multiport fuel injection relay to the volume air flow sensor and is grounded by the engine control module. The volume air flow sensor generates a pulse signal as it repeatedly connects and disconnects between the 5V voltage supplied from the engine control module and ground.
