Circuit Description

Variable Intake Manifold (VIM) solenoid controls intake air vacuum switching valve opening and closing induction control valve for intake manifold runners. VIM solenoid is controlled by PCM. When engine speed is less than 3600 RPM, VIM solenoid is On and induction control valve is closed. When engine speed is 3600 RPM or more, VIM solenoid is Off and induction control valve is opened. IF PCM detects short circuit in VIM solenoid, DTC P0662 is set.
