Canister Closed Valve Vacuum Switching Valve (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.
- Disconnect electrical connector at Canister Closed Valve Vacuum Switching Valve (CCV VSV). On Tacoma, CCV VSV is located in engine compartment, on bracket bolted to inside of driver's side front fender panel. See Figure.
- Remove CCV VSV. Using ohmmeter, check that continuity exists between electrical terminals on CCV VSV and that resistance is within specification. Resistance should be 25-30 ohms at 68°F (20°C) and 33-42 ohms at 248°F (120°C). Replace CCV VSV if no continuity exists or resistance is not within specification.
- Ensure no continuity exists between each electrical terminal and body of CCV VSV. Replace CCV VSV if continuity exists between electrical terminal and body of CCV VSV.
- To test CCV VSV operation, apply air pressure to port "A". Ensure air flows from port "B". Perform STEP 1 in illustration. See Fig 1.
- Apply battery voltage and ground to electrical terminals on CCV VSV. Apply air pressure to port "A". Ensure air does not flow from port "B". Perform STEP 2 in illustration. See Fig 1. Replace CCV VSV if defective.
