DTC P1660-14: Air Intake Control Valve Circuit Short to Ground or Open [12/2017 - 10/2020]: Description
The air cleaner is equipped with two inlets, one of which is opened or closed by the Air Intake Control Valve (AICV). This system reduces intake noise and increases engine power at low-to-high engine speed range. When the engine is operating in the low-to-mid speed range, this control operates the AICV to close one of the air cleaner inlets. When the engine speed is more than 3600 rpm, the ECM activates VSV and opens the AICV.
