PN-Request: 4agze vsv

Kevin mr2 1985 · 05-07-2009, 01:35 PM

im looking for the part number for a 4agze vsv for fuel pressure up and for the abv. also this is the part number of a vsv from a toyota truck could you please find it and give me a description of the part and the vehicles it was in? 90910-12085 and 90910-12084? they are almost identical.

I'm a little confused myself about VSV part numbers. I just received an outlet piece off a Jspec SC12. It had a VSV on it, intended for hook up to the ABV. The bracket the VSV mounts on had a generic type part number (not an MR2 specific part number) and the VSV itself had no part number, just the manufacturer's name: "Aisan". Go figure.

A separate and different VSV mounted on the engine bay wall (rear) modulates the vacuum line from the manifold over to the FPR. With the VSV plugged in in between.

well i found the part numbers are 25860-16020 and 25860-16010 i dont kow which is which but i need both of them.

I'll be damed. The last four digits match the ABV VSV that just arrived. 16010.

You could take almost any VSV from a jap car from the 80's and stick any VSV in that gives off the correct resistance and is made by Aisin, or Nippondenso. That's because your ABV is disabled or removed. Your're just fooling the ECU.

The FPR Vsv I have is the real McCoy. But my spare is a VSV from a Scoobydoo (subaru) Nerdmobile.

My SC and Alternator Idler pulleys are new BMW parts. My ABV is made by Bosch and intended to go on a Saab.

What I'm saying is . . . start thinking OUTSIDE the BOX. Because with Yota factory support for SC's gone . . . its that or let the grass grow up around it.

Kevin mr2 1985 · 05-10-2009, 02:33 AM

yah but how do i measure the resistance?

Jackstand Queen · 05-10-2009, 11:50 AM

Resistance is measured in Ohms. Any multimeter can measure Ohms. With fuel injection, a multimeter is almost as basic as a wrench or screwdriver. With it you can find the electronic problems which owners of 20+ year old cars are afflicted with. For example, to adjust the Throttle position sensor, you must measure resistance across its terminals.

I am going to encourage you to think outside the box. You can have my spare ABV related VSV for 150% of what it would cost to buy a Radio Shack multimeter, gas to get the junkyard, and the $5.00 the part will cost. Postage not included. Your choice.

By the way does it look like you can make it to the Meet in Medford?

Kevin mr2 1985 · 05-10-2009, 12:28 PM

oh ill go look but i just needed to know what it was measured with. ty for help

Jackstand Queen · 05-10-2009, 07:26 PM

Pick up a couple extra ones that look like they might work. After you knock out the easy VSV that doesn't do anything other than fool the ECU (the ABV one).

At room temperature, the restistance should be 33 to 39 ohms.

Then you can sort through them and start testing for function for the FPR VSV. You'll need to hook it up to 12 volts, and then blow through a piece of vacuum line at the same time. I looked up the result you will need to see in the BGB. You'll want the type of VSV that has vacuum line nipples at either end of the cylinder. When there is no voltage applied, there is no air flow through the VSV. When voltage is applied, air flows through the VSV.

Yes this garbage is hard to do . . . . by the way.

Kevin mr2 1985 · 05-10-2009, 10:35 PM

okay your saying that the vsv needs to have a vacuum line connection on both sides?

Jackstand Queen · 05-10-2009, 10:58 PM

Ok some VSV's have two vacuum outlets on a single side of the cylinder.

A VSV is an elecrtically operated magnetic coil, which actuates an air valve.

So the one for the FPR has a vacuum outlet on either end of the cylinder.

If one end has two outlets, but still has a third at the other end of the cylinder . . . you can plug up the extra one. Or run a boost gauge, or hobbs switch off of the extra one.

kk that makes sense ill go check out the wrecking yard soon
