IACV Control Circuit
IACV Control CircuitDESCRIPTION
IACV Control Circuit:
This circuit opens and closes the Intake Air Control Valve (IACV) in response to the engine load in order to increase the intake efficiency (ACIS: Acoustic Control Induction System).
When the engine speed is 4,700 rpm or more and the throttle valve opening angle is 60 degree or more, the IACV is open (VSV: OFF). At all other times, the IACV is closed (VSV: ON).
