ACIS Control Circuit

CIRCUIT DESCRIPTION




This circuit opens and closes the Intake Air Control Valve in response to the engine load in order to increase the intake efficiency (ACIS: Acoustic Control Induction System).

When the engine speed is 4,100 rpm or less and the throttle valve opening angle is 30° or more, the ECM turns the two VSV ON or OFF and operate the Intake Air Control Valve.
