Canister Close Valve
- Canister Close Valve (CCV) is located near EVAP canister. Measure resistance between CCV terminals. Resistance should be 24-25 ohms at 68° F (20° C). If resistance is not as specified, replace CCV.
- Remove CCV. CCV should be open. Blow air into port "A" and verify air escapes from port "B". See Fig 1. Close CCV by jumpering one CCV terminal to battery positive terminal. Jumper other CCV terminal to battery negative terminal. Blow air into port "A" and verify air does not escape from port "B". If air does not escape from port "B" when CCV is open and/or escapes when CCV is closed, replace CCV.
