tacho is fixed

Just the tacho, or everything? What was wrong with it? What did you change? Asking as other forum members will search and find this thread, so it's useful to say what you did.

Yes there is. Toyota will only charge you a couple of hundred (maybe more) for one or you could tell me exactly which one is broken (a couple of pics would be good) and I may have a spare here at the right price. I need to know details so I can match the mounting if possible and get the orientation of the plug that connects to it right.

Might be best to contact me through the Aussie Forum.

Had a look at your previous pics and did some checking of the EPC.

Take a look at the part number on the broken VSV and if it matches these numbers I have the complete unit with the bracket and hoses attached.

25800-54121 or 25800-54150

I will need to test it to see if it works. Sometimes the VSVs are faulty.

The top VSV may have a part number 25819-54090 and the bottom one 25860-54060.

25819-54090 should be the upper one. 90910-12089 is a number which I can't find.

I'll have a proper look at the part numbers on the VSVs I have tomorrow.

25819/54090 is the one i need i havnt damaged the other, not to say its not fauty.

[NiftyNev]

That one I have. I will test it later today and get back to you. Testing is easy. You just need a couple of lengths of vacuum hose and a power source. Disconnect the plug from the VSV. Install a piece of hose to each port of the VSV. You should not be able to blow through the end port when power is not supplied. When power is supplied (12V Positive and Negative to the two pins) the valve should open.

Here's a topic on the Aussie forum with a simple animation I did a few years ago.

That is how all the VSVs operate but their operation depends on other sensors on the engine, such as the TPS and others, as to whether they operate at the correct time. This envolves a lot more understanding of how the system works and almost impossible to explain on a forum.

Thanks nev it is all very confusing for sure. I actually tried to get the only toyota diesel machinic here to do this work but he wont touch surfs would not even do a diagnostics for me lol fun fun although i am enjoying da challenge

[NiftyNev]

VSV has been tested and is ok. Join the Aussie forum, make me a reasonable offer and it's yours. I can't PM you on this forum. If you join the Aussie site you will not be able to PM me but just post a message in the beer garden and I will PM you.
