Circuit/System Description
WARNING: This page is about a different car, the 2008 Suzuki Swift +, 2008 Pontiac Wave, and 2008 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.
The engine control module (ECM) supplies the intake manifold tuning (IMT) valve position sensor with a 5-volt reference circuit, a low reference circuit, and a signal circuit. The IMT valve position sensor provides a signal voltage that changes relative to the IMT valve angle.
