Circuit / System Description
An intake manifold tuning solenoid valve is used to change the intake manifold plenum configuration. When the intake manifold tuning solenoid valve is open, the intake manifold is configured to one large plenum. When the intake manifold tuning solenoid valve is closed, the intake manifold is configured to two smaller plenums. The intake manifold tuning solenoid valve improves engine performance at low and high engine speeds.
Ignition voltage is supplied directly to the intake manifold tuning solenoid valve. The engine control module (ECM) controls the intake manifold tuning solenoid valve by grounding the control circuit via an internal driver switch. The primary function of the driver is to supply ground for the intake manifold tuning solenoid valve. 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.
