Lexus ES 300 Forum : “HOW TO REPLACE THE VCV VALVE”

Hi dtny ... It's time for you to purchase a Chilton's for your ES 300. Here's a link to Amazon.com where you can purchase one for less than $15. Always good to have around. Good luck!

Chasing codes are you?  The VCVs are under the plastic engine cover. There are several.

Here are some concerns.  If you "tried" to clean the throttle body, but didn't take it off, the valves that control the EGR will be damaged by some cleaners.  As the post said, you can get a Chiltons, or others.  You could also subscribe to the Toyota TIS site and get the real factory pubs.    Get to a autoparts place and let me know the code P0XXX?, and maybe I can help.  Your car is ODB-II, and the connector is where the fuses are by the drivers left knee.  The ODB-II codes are the real deal.
