Fuel Injection Control
The amount of
fuel injection is basically determined by the
air flow sensor (
AFS) output frequency corresponding to the amount of intake air. With the increase of air flow sensor output frequency, the amount of fuel injected increases and as the air flow sensor output frequency decreases, the amount of fuel injected decreases.
