Vacuum Switching Valve (VSV) Test: Swift
- Disconnect vacuum hose and connector from VSV. Check VSV solenoid by applying battery voltage to valve terminals. Airflow should flow from port "A" to port "B". See Fig 1 .
- Check for continuity between VSV body and one valve terminal. Continuity should not be present. Check VSV for continuity between connector terminals. Continuity should be 24-30 ohms. Replace VSV if continuity is not as specified.
