Circuit Description
WARNING: This page is about a different car, the 2004 Suzuki Swift + and 2004 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.
An ignition 1 voltage is supplied directly to the intake manifold tuning (IMT) valve solenoid or variable geometry induction system (VGIS). The control module controls the IMT solenoid by grounding the control circuit via an internal driver switch. The primary function of the driver is to supply ground for the controlled component. The control module monitors the status of the driver. If the control module detects an incorrect voltage for the commanded state of the driver, DTC P0660 sets.
