- Check EVAP canister air valve for damage and check resistance of air valve. Resistance should be 25-30 ohms at 68°F (20°C) between two terminals and 1 megohm or higher between terminal and valve body. If resistance is as specified, go to next step. If resistance is not as specified, replace vent valve.
- Blow air into nozzle "A". Air should come out of nozzle "B". Connect 12-volt battery to valve terminals and blow air into nozzle "A". Air should not come out of nozzle "B". See Fig 1 . If result is not as specified, replace air valve.
