Air intake control valve circuit
P1113 Air intake control valve circuit
Description:
The air cleaner is equipped with 2 inlets, one of which is opened or closed by the Air Intake Control Valve (AICV).
This system reduces intake noise and increases engine power.
When the engine is operating in the low-to-mid speed range, the ECM deactivates the Vacuum Solenoid Valve
(VSV) and allows the AICV to close one of the air cleaner inlets. When the engine speed is greater than a
specified value the ECM activates the VSV and the applied vacuum activates the AICV to open both of the air
cleaner inlets.
