Component Description
The swirl control valve control vacuum check switch detects vacuum signal to the swirl control valve, and sends "ON" or "OFF" signal to the ECM.
When vacuum is supplied to the valve, the swirl control valve control vacuum check switch sends "OFF" signal to the ECM. The swirl control valve control vacuum check switch is not used to control the engine system, it is used for on board diagnosis.
