Hissing Sound When Removing Fuel Cap: Notes
NOTE:
After each service or repair procedure has been completed, reconnect all components and perform DRIVE CYCLES
in SELF-DIAGNOSTICS - CNG, FLEX-FUEL & GASOLINE article. Ensure PENDING CODE CHECK & EVAP MONITOR "BYPASS" CHECK is performed. Clear DTCs and repeat QUICK TEST
in SELF-DIAGNOSTICS - CNG, FLEX-FUEL & GASOLINE 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.
