Circuit Description
WARNING: This page is about a different car, the 2006 Suzuki Verona. However, it is still accessible from the selected car via links, so may be relevant.
The Engine Control Module (ECM) operates a solenoid to control the Intake manifold Tuning (IMT) valve solenoid electrical. The solenoid is normally closed. By providing a ground path, the ECM energizes the solenoid.
