Hissing Sound When Removing Fuel Cap: Notes
WARNING: This page is about a different variant/trim than selected.
NOTE:
After each service or repair procedure has been completed, reconnect all components and perform DRIVE CYCLE PROCEDURE
under DIAGNOSTIC MONITORS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed. Clear DTCs and repeat QUICK TEST
in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article to ensure all EEC-V systems are working properly and DTCs are no longer present.
NOTE:
Enter this test only when all steps under QUICK TEST have been successfully completed and hiss still exists when fuel cap is opened or if directed here from another test or chart.
