Resonator: Description and Operation

System Description 

The resonator control system decreases air intake noise.

Operation

When the engine speed is below 3,800 rpm, the ECU supplies current to the resonator control solenoid valve. This opens the solenoid valve
sending intake manifold vacuum to the resonator diaphragm.
