Circuit / System Description
An ignition?1 voltage is supplied directly to the intake manifold tuning (IMT) valve solenoid. The engine control module (ECM) controls the IMT valve solenoid by grounding the control circuit via an internal driver switch. The primary function of the driver is to supply ground for the IMT valve solenoid. The ECM can determine if the control circuit is open, shorted to ground, or shorted to a voltage by monitoring the voltage on the control circuit.
