Pressure Switching Valve Vacuum Switching Valve (Avalon, Camry, Camry Solara, Highlander, Land Cruiser, Sequoia, Sienna & Tacoma)
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2003 Toyota Tundra, 2003 Toyota Tacoma, 2003 Toyota Sienna, 2003 Toyota Sequoia, and 2003 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
- Remove pressure switching valve Vacuum Switching Valve (VSV). For pressure switching valve VSV location, see PRESSURE SWITCHING VALVE VSV LOCATION table and Figure-Figure .
- Remove pressure switching valve Vacuum Switching Valve (VSV).
- Using ohmmeter, ensure continuity exists between electrical terminals on pressure switching valve VSV and that resistance is within specification. See PRESSURE SWITCHING VALVE VSV RESISTANCE table. Replace pressure switching valve VSV if no continuity exists or resistance is not within specification.
- Ensure no continuity exists between each electrical terminal and body of pressure switching valve VSV. Replace pressure switching valve VSV if continuity exists between electrical terminal and body of pressure switching valve VSV.
- To test pressure switching valve VSV operation, apply air pressure to port "E". Ensure air does not flow from port "F". Perform STEP 1 in illustration. See Fig 1 and Fig 2 .
- Apply battery voltage and ground to electrical terminals on pressure switching valve VSV. Apply air pressure to port "E". Ensure air flows from port "F". Perform STEP 2 in illustration. See Fig 1 and Fig 2 . Replace pressure switching valve VSV if defective.
