WARNING: This page is about a different car, the 2003 Lexus LX 470. However, it is still accessible from the selected car via links, so may be relevant.
- Remove vacuum switching valve. Using an ohmmeter, check that there is continuity between terminals. Resistance should be 24-30 ohms at 68°F (20°C). Check that there is no continuity between each terminal and body. If VSV is faulty, replace it.
- Check that air flows from port "A" to "B". See Fig 1.
- Apply battery voltage across terminals. See Fig 1. Check that air does not flow from port "A" to "B". If VSV is faulty, replace it.
