VSV For Evaporative Emission (EVAP): Inspection

1. Disconnect the 2 EVAP hoses from the VSV.
2. Disconnect the VSV connector.
3. Remove the bolt and VSV.

Using an ohmmeter, check that there is continuity between the terminals.

Resistance: 27 - 33 Ω at 20°C (68°F) 

If there is no continuity, replace the VSV.
