vsv

Hello I have just purchased a 1978 40 series and learned that my EVAP system is 100% not intact (Ignorantly didn't know this was something i needed to look for). Truck smells horrible of gas vapor. Wife is not happy. (common story from my research) Anyway I have been trying to learn/understand...

I'm hoping that someone can help explain how the idle up works in my 1999 Prado, 1KZTE... There are two VSV's connected to the top of the Idle Up Actuator: VSV No.1 and VSV No. 2. The Idle Up Actuator has two ports on the top. I believe the Idle Up Actuator controls the small butterfly in the...

Hey guys, I've got an issue I'm hoping someone might be able to help me resolve. '86 HJ60 with a 2H. No EDIC because it's the Canadian spec so instead it has the butterfly shut off valve like the 12HT. The problem I'm having is on start-up. I've searched all over and I can only find problems...

So, found out I have a leak in the plenum gasket, I’m pulling the upper off when i get the parts in, but under there I know are a bunch of VSV and VCV, I know some are related to ERG, I was getting the code a while back but did the resistor fix and now don’t really need a lot of these under...

Got a 91 that sat for 15 years, bringing her back to life slowly and discovered the truck's missing the Vacuum Control Valve, # 90925-03057 (discontinued for many years). Is there compatibility with 1FZE VCV # 90925-03192 with the 3FE? I've searched and found threads, but haven't found a...

Hi all, I recently acquired my first LC and have been working on baseline maintenance with the help of existing mud threads. As I was going through the 5mm vacuum lines, I noticed that one of the VSVs mounted on the driver's wheel well appears to be broken. Based on the FSM, I think this VSV is...

Preferably local to DFW. I bought my FJ62 engine without the smog stuff and I'd like it back. I need, EGR, EGR valve, smog pump, manifold air injection rail, air injection check valve, silencer, and VSV's, air box hoses. I need the exhaust manifold as well as mine was welded shut. I don't need...

When I was searching for a replacement AC Idle Up Vacuum Switching Valve for my 87 FJ60, I could not find the definitive post that said, "yes, I have a solution, here is the part number, and it is a 100% form fit function replacement for the OE" I found the part and installed it today. I can...

I snapped off the VSV nipple that runs to my dizzy advance. Is this a repairable item? I’ll pull it and see if I can repair it. Anyone done this before? Thanks!

Hi Y'all, Either due to a previous owner or industrious squirrel, my driver's side wiring harness is a rat's nest of shorts and crossed wires. Normally I'm not very impulsive but thanks to vodka tonics and a recently ex-girlfriend I did what any logical 1983 FJ60 owner would do. I took my...

Looking for a VSV for EGR in good working order (pn 90910-12079)

I have a new to me LX450. Had a 401 when I got it. The PO just changed out the VSV thinking that might be the cause. With it being out and exposed now, it helped me diagnose a little bit. EGR works fine if I draw vacuum on it directly (engine stalls). I ohm the VSV and get ~36 which is...

Hi guys chasing up the plug to suit my new 12ht shut down VSV valve would anyone have a lead on where to buy this type of plug.

Hey guys, My 89 62 has been running great but all of a sudden two days ago the engine cut out as I was driving home from work. Then when I tried to start it again it would start and then immediately cut out. Turns out the the shut down VSV was not working properly or so it seemed, as it was...

Hey guys. Working on my 5lt franken-engine. Trying to trouble shoot and put back together my vacuum system. Old engine had no EGR system and the new engine had it all deleted. It would help a bunch if I could ID all the parts and know for sure what the truck wants/needs in terms of vacuum...

In short, I have a fabulous 96 LX that is throwing the EGR code. It also doesn't help that I must go through emissions testing. Through the several searches I have achieved the following; HOWEVER the code remains.... -EGR tests out -Modulator tests out -VSV works -intake port is spotless -temp...

Went to my local Yota stealership to get some info and pricing for the Toyota VSV for my 96 LX450 however the Parts guy told me there are two ? is this true because ive only researched on this forum and have seen one. If there is two where does the second one go, im only familiar with the one...

Hey Mudders, In preparation for a long road trip, including a stop at Overland Expo East, I took my truck over to a dealership here in town (Wolfchase Toyota) to get the check engine light diagnosed. It's a 1994, so no OBD II, and I couldn't find anywhere else to take it on fairly short notice...

I have a 1991 3FE FJ80. It has no VSV connected, but everything seems to run okay and I still get about 14 MPG. It has been disconnected since I bought it. I'm sure it was disconnected for a good reason (?). What can I expect if I reattach this? What should I look for before I reattach this?
