Idle speed control valve location??

Does anyone know where is this valve located on the throttle body and how to remove it for cleaning? My 07 Rav4 I4 (87K miles on the odometer) has low idle speeds when pulling up to the red light in stop N go traffic and with slight vibrations. After reading couple posts here, I want to clean this valve or sensor to see if it helps with this issue.

Could anyone post a picture of this valve location in out engine bay and tips to remove it for cleaning?

Thanks in advance.

There is NO idle control valve on your RAV4. The idle is controlled by the computer. There is a throttle body with an air vane controlled by a motor and a throttle position sensor to send feedback to the computer. I suggest you download the service manual. Look under "2AZ-FE Engine Control System" and then "Throttle Body"--there are detailed instructions on how to remove it. You could then thoroughly inspect and clean the throttle body. Download the manual here:

Thanks for the info. It seems like I have to replace the throttle body gasket when removing it for cleaning. I took out the air intake box today and saw couple steel pipes that are connected to the throttle body. I have to be very careful when removing the hoses and not to break anything. I will give it a shot this weekend.

I wouldn't suggest that you remove the entire TB just to clean it out, particularly the IAC valve. I would just try to spray some TB cleaner into the intake and orifices first. That has cleared up any IAC related problem for me on several vehicles. Don't get me wrong removing the TB and giving it a thorough cleaning may be needed in some rare situations, but I doubt with just 78k on the clock you built up that much gunk.

I just looked yesterday at how deeply buried the Throttle body is and I really don't feel like messing with that much trouble unless it is really acting up badly. I have done what RAV4Don mentioned in the past. Just spray some cleaner in and it runs better.

Yes, access on these engines can be a royal PITA for doing engine work. When I had the engines out of my Camarao and Chevy truck, I took the time to completely rebuild the TBs. There are aftermarket rebuild kits with all the replacement parts and gaskets. Some have injector rebuild parts. TBs are simplier than carbs to rebuild from my experience.
