VSV Valve Options

[DIONYZUZ]

Hello everyone,
I have had problems with my Evaporation system, and my mechanic said he would need to replace the charcoal canister and the VSV Valve. I have a tech manual that I've been looking through and I've been searching on the web and found a good deal on the canister at toyota parts barn. I found another name for the charcoal canister, which is the vapor canister, and I'm thinking that the VSV Valve migh have another name. Or is the VSV valve included in the vapor canister?

Bi-metal vacuum switching valve (BVSV) isn\'t part of the charcoal canister -- if it\'s the one for the evaporation system, it\'s connected to the charcoal canister by a vacuum line but is actually screwed into the same portion of the head as the water temperature sensor.

90925‑05068 -- $53 from 1sttoyotaparts.com

It\'s a blue-green plastic piece with two vacuum lines attached to it. It\'s the one on the right side of this photo (not the circled item).



Easy to test, I used a drink box straw.

A) Cool the BVSV to below 35°C (95°F) with cool water. Blow air into the top port and check that the BVSV is closed.

B) Heat the BVSV to above 54°C (129°F) with hot water (I placed it upright in a pot with the water up to the hex head). Blow air into the port and check that the BVSV is open.

Replace if it fails, or re-install if it passes. Use a mid-strength threadlocker to seal it, Three Bond 1324 or equivalent.
