Vacuum Passage Inspection
WARNING: This page is about a different car, the 2011 Suzuki SX4. However, it is still accessible from the selected car via links, so may be relevant.
Start engine and run it at idle speed. Disconnect purge hose No. 3 (1) from EVAP canister purge valve (2).
With finger placed against disconnected hose, check that vacuum is applied.
If it is not applied, clean vacuum passage by blowing compressed air.
