Replacement of the VSV (in Spanish)

Thanks for such a good write up. One thing I wanted to add is that for 93-94 models on the bracket with the VSV is also a pair reed VSV as well and a number of extra vacuum lines. This makes it impossible to pull the bracket out of the clamshell to screw on the new VSV. Not a big issue however because to get to the screw on teh top of the VSV all that is needed is to remove the throttle body and then you have great access from the passenger side of the vehicle (not as big a task as I though it would be).

I don't know if it's just me but I am not able to see the images. I would really appreciate it if you can help me out...I have a 1996 Toyota Land Cruiser and want to change the vsv. I have heard that to do that I need to remove the intake plenum, this is why I am interested in seeing those images. Any other tips and advice would be very much appreciated as well. Thanks!
 
wow...bummer...the write up was great with those pics. I don't think I saved a copy of them either, perhaps someone else did.
 
Bummer; I referred to this exact thread when I had my intake all apart and the pics were there as of May. I tried referring to a cached version of the page and no luck.

When I get home I'll check my other puter to see if I saved the pages as pdf's.
 
If you guys don't mind, would you please post the images or PDF version of this writeup if you are able to find it?

I am about to embark on this myself this week and would love some picture guidance.


Thanks,
Andres G
 
I third the notion for the possibility of someone posting archived pics.

Thanks !
 
REPLACING THE VSV

Ok, Here is shown how to replace the VSV, Vacuum Switching Valve. This valve generates a persistent CEL, and can cause an excessive fuel consumption. The ODB II error shown is a P0401 – EGR insufficient flow.

In this disassembled intake you could see the VSV. It's hard to see, It's in the intake chamber (seems a jail, each cilinder intake as its rungs) This first photo is from a previous alia176 post:

First is to unplug the vacuum hoses. Replacing them could be a good idea. This guy used fuel 6mm inner diameter hoses.

second thing is to aside the admission support bracket:

This support bracket should be loosen on its base, below the car. It's quite complicated…

You don't need to unbolt it completely. It's just to aside it. Although everything You should have little girl hands, as he does, to work inside the intake chamber.

Once the support bracket is asided, You should loose the EGR vacuum modulator (the green mushroom):

Don't forget to unplug the vacuum hose attached to the VSV. (arrowed in purple) This guy broke down that hose. Arrowed in green is one of the two screws that hold the VSV. Both need a 12mm key. The other screw can be seen inside the chamber, it's too arrowed in green on the next photo.

Arrowed in purple, hard to see, is the VSV. Loose both screws, one from the left side of the intake...

…And one from below the car. It's not difficult to see. (arrowed in purple). You can see too the VSV from below (arrowed in purple). Both screws are hardly screwed and it's easy to pass their heads off...

Not much orthodox, but it makes its function. You can see here how. The VSV electrical plug is arrowed in purple.

Once loosen the VSV, don't forget to unplug the other vacuum hose and the electrical plug.

Detail of this second vacuum hose:

And from the electrical sensor plug:

Once out, unscrew the old VSV and place the new one. Quite simple.

voilá.

Mounting is the reverse. Don't forget any screw, hose or plug.

Excuse this pathetical English. (Again)
Pics are not showing up
 
Just got the code for the first time yesterday and looking to dive into this so any picture help would be great.
 
Seems like pics are gonzo. Bummer, seemed like a helpful pictorial thread.

I unfortunately don't have photos from this thread but recall back when I tackled and EGR code that some pictures were missing going back as far as 2012. Here is a write up I did at the time trying to compile helpful threads and adding photos of the job as I went to try and make it easier for me as well as the next guy that had to tackle the job. Hope it helps.

Hi, I have a 94 and I'm having a tough time loosening the forward 12mm bolt for the VSV mount bracket. Would removing just the throttle body allow for loosening this bolt? I'm hoping that I can replace the VSV with only removing the throttle body. It's been a while but if you remember, please let me know.

Did you ever figure this out? Want to replace my VSV but don’t want to take the TB off again.

Not sure if the same as a 1997, but on mine I was able to locate the VSV and put a bright piece of tape on it, then was able to easily see it from under the vehicle, long extensions and it was easy to remove and replace
