1. Using an ohmmeter, check that there is continuity between the terminals.
Resistance: 30-36 ohm at 20 °C (68 °F)
If there is no continuity, replace the VSV.
2. Using an ohmmeter, check that there is no continuity between each terminal and the body.
If there is continuity, replace the VSV.
3. Check that air does not flow from ports E to F
