Yes, i think it was p0440 or something like that... that part is about $950 from the lexus dealer but if you use the search there is a thread where i did this same service and i posted the part number for the toyota part off a corolla i think.. and its about $150...
Cheers

Sewell has it listed for $45.02. We may be talking about two different items. This is a small item that has two screws attaching it to the lid of the airbox. It has one electrical connection and a vacuum connection. No way could it ever be $950.00. Sewell calls it the vacuum switch valve. Others add the ing.

I dont remember the code anymore, but there is a thread on here by me where i chased a evap code for a few months... did the gas cap, checked the airbox connection. and it was a VSV vaccum switching valve. its on the back of the system right beside the charcoal filter. JAB i think was the person who gave me the part number... i even had toyota install the corolla part on my lexus for me..

Vapor canister
You have mentioned that the Corrolla part worked on your Lexus RX 300 (1999)
Please provide the Corrolla part # that can work on the Lexus RX 300
for the vapor canister.
thanks

The part that I bought, only available at a Toyota dealer, was p/n 90910-12267. In July 2011 it cost me $125.00. My recollection is that Lexus changed the configuration of the charcoal cannister in 2000 or 2001, and this part would no longer be applicable. I also recall that a possible explanation for a charcoal-cannister related CEL was brittle vacuum lines in the cannister; I recommend that you check those first (I did not.) They are easily and inexpensively replaced. Good luck.

To check a VSV try to blow through it. Some are normally closed some are normally opened. Energize it and try to blow through it again. If it clicks when energized and that changes whether or not you can blow through it then it is fine.
