Circuit Description
The Variable Intake Manifold (VIM) solenoid (intake air VSV) circuit controls the induction control valve that the length of a port is switched. The VIM solenoid is controlled by the Powertrain Control Module (PCM). When the engine speed is less than 3600 RPM, the VIM solenoid is "ON" and when the engine speed is more than 3600 RPM, the VSV is "OFF". The induction control valve is closed at the VIM solenoid is "ON", and it is opened at the VSV is "OFF". If the VIM solenoid circuit is opened, DTC P0660 will set.
