| Position | At pneumatically operated resonance flap | ||
| Task | Actuating resonance flap | ||
| Design/function | The electromagnetic resonance intake manifold switchover valve is actuated by a GND signal supplied by the engine control module. Voltage is supplied by circuit 87. If the resonance intake manifold switchover valve is actuated, intake manifold vacuum flows to the diaphragm unit and operates the resonance flap. |
