Canister Closed Valve Vacuum Switching Valve (Camry, Camry Solara, Celica, Corolla, ECHO, Highlander, MR2, RAV4 & Tacoma)

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Toyota Tacoma, 2002 Toyota RAV4, 2002 Toyota Prius, 2002 Toyota MR2, and 2002 Toyota Highlander. 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). See Fig 1-Fig 9 . Remove CCV VSV.
NOTE: On ECHO, charcoal canister must be removed for removal of CCV VSV. Charcoal canister is located near fuel tank. See Figure. For removal of CCV VSV, see CANISTER CLOSED VALVE VACUUM SWITCHING VALVE under EMISSION SYSTEMS & SUB-SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION - 4-CYLINDER article.

Using ohmmeter, check that continuity exists between electrical terminals on CCV VSV and that resistance is within specification. See CANISTER CLOSED VALVE VACUUM SWITCHING VALVE RESISTANCE table. Replace CCV VSV if no continuity exists or resistance is not within specification.

CANISTER CLOSED VALVE VACUUM SWITCHING VALVE RESISTANCE

Application

Ohms @ 68°F (20°C)

Camry

24-30

Camry Solara & ECHO

⁽¹⁾

Celica & Highlander

24-30

Corolla, MR2 & RAV4

25-30

Tacoma

⁽¹⁾

⁽¹⁾	Resistance should be 25-30 ohms at 68°F (20°C) and 33-42 ohms at 248 °F (120°C).

Using ohmmeter, 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 10-Fig 15 .
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 10-Fig 15 . Replace CCV VSV if defective.
