EVAP Vacuum Switching Valve (All Models)
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 EVAP Vacuum Switching Valve (VSV). For location of EVAP VSV, see EVAP VSV LOCATIONS table and Figure-Figure .
- Using ohmmeter, ensure continuity exists between electrical terminals on EVAP VSV and that resistance is within specification. See EVAP VSV RESISTANCE table. Replace EVAP VSV if no continuity exists or resistance is not within specification.
- Using ohmmeter, ensure no continuity exists between each electrical terminal and body of EVAP VSV. Replace EVAP VSV if continuity exists between electrical terminal and body of EVAP VSV.
- To test EVAP VSV operation, apply air pressure to port "E". Ensure air does not flow from port "F". Perform STEP 1 in illustration. See Fig 1-Fig 5 .
- Apply battery voltage and ground to electrical terminals on EVAP VSV. Apply air pressure to port "E". Ensure air flows from port "F". Perform STEP 2 in illustration. See Fig 1-Fig 5 . Replace EVAP VSV if defective.
