This is a good site for rims...

https://www.wheel-size.com

You can search by vehicle to find your specs, then search by rim size to find other vehicles with wheels which will fit. Stick with...

The most troublesome part of accessing the bulbs on a stock Previa is getting the sliding tray/cig lighter assembly out in order to remove the radio. If your aftermarket radio allows you to get it...

The coolant lines servicing the EGR valve are part of the main cooling system so you'll just be checking the reservoir level and adding coolant there if necessary. If you plan on disconnecting the...

Much info on this stuff here. Do several different searches and lots of reading. Also check out this page... https://zenseeker.net/Previa/ ... it is very worthwhile browsing and has a lot of common...

Although I’m not often a gambler, I’d wager large sums of money that every Previa in existence which has never had the fuel injectors serviced has lower insulators which have turned to rubble.
How...

First time doing the pinion seal replacement for me so I thought I'd add to this thread with some pics. There is a pretty good thread on the Vans forum -...

Rebuilding/reusing is ethically admirable too. My MO is to have a small supply of spare wear-prone parts on hand, salvaged from scrap yards. The scrap yard parts ^usually^ work if you're selective in...

With nicer temperatures coming up soon in the Fall, those couple of months would be an ideal time to fix all the blower system problems prior to the arrival of Winter. Your vehicle has had plenty of...

Sometimes if you live where there are winters with salted roads and your exhaust system has not been touched in years, you end up with rusted "lumps" rather than bolts or nuts. No alternative at that...

My California spec '91 has an OBD1 and a different (single) code for EGR problems, but the code was from a sensor in the passageway sending a temperature signal to the ECM. On mine if the passageway...

My suspicion is still with something in the modulator circuit. Insufficient flow could also mean no flow, I would expect. The EGR valve is most likely not opening, but as you said, the EGR valve...

Re egr problems ... it must be verified that the vacuum modulator/solenoid is functioning as the very first step in the process. It is this part which tells the egr valve to open. Search vacuum...

Whenever the EGR system has a problem it must be verified that the vacuum modulator / solenoid is functioning. It is this component which is the brain for the EGR valve itself, and it commonly fails...

Kinda by accident I came across this oem stock wheel/tire set up, which I really like for the previa... it's the standard wheel on the Lexus GS300, a 16 x 7.5 rim with the correct center bore (60.1),...

I recently discovered a potential downside to this mod depending on your level of memory loss. Mine is significant so it is definitely detrimental.

There is a relay in the headlight circuit called...

Yes, regarding emergency starting.
If it was me I'd get myself the necessary jumper cables and do the connections mentioned above so that you know what to do/expect while the starter is actually...

I agree, and this is in no small part due to the way this site is administered. Users are encouraged to search first, and if they do post, to try to find a relevant existing thread to post in before...

You're right about the fan switch. I was unaware that new replacements were available.
Heater valve. Typo.

Idle speed/air control valve
Muffler entire rear pipe section (if it's the original Toyota [big round can] in good shape)
Drive shaft
Starter
Brake rotors (they can get deeply pitted by salty...

Re your egr issue, hopefully you've fixed the problem by cleaning the passageway. I believe that the passageway gets blocked by carbon at the throttle body when the egr system stops functioning and...

Welcome to Previa ownership, or at least to the toyotavantech site. It's nice to see new posting members in these days of 30 yr old Previas.

Finding the faulty component is still necessary. Check out whether the switch is bad - it's usually the pigtail connector contacts which burn up - and decide from there. This thread also has switch...

Well, if your intent is to return the blower to full functionality and stock circuitry, you'd buy a new switch (8473295D00 $83, or get one from the scrap yard) and determine all the parts of the...

Good. One item to rule out.

If you have page 19 of the wiring diagrams at the back of the manual, take a look at that.
If not, here it is anyway from my manual...

I was going to point you to the page of the manual where the relay testing instructions were, but looking at my '91 manual there is an unfortunate typo and the testing method is subsequently wrong!

It would be worth keeping an eye open for Previas coming into your local picknpull etc to get yourself a spare Idle Air Control Valve. It's worth having one. Plus, if there's a sensible opportunity...

We can get this figured out. First, let us know if you have a repair manual.

What about using the throttle body which solved the cold start problem and swapping out the idle air valve with the one which didn't have the high idle problem. That seems like a logical step. Beware...

Did you sell this?

So, after a year of fine operation, then a year of intermittent check engine light, my EGR system has now failed again - the vacuum modulator specifically, again, so I took it off to investigate.

This is it right here on my '91. On mine, the two lower clips are the removable/reusable ones with the screw and the two upper ones are the push-in/break-out type.

I'm one of those traitors with a Previa ('91 M/T), but I came across this thread and thought I'd add my experience, such as it is.

Many years ago, before I cared/thought too much about what I was...

I replaced my original '91 driver's side seatbelt today with one from a '93 model. Not a bad job, but a little fiddly to get the panel loose and, as is typical with bodywork stuff, prone to breaking...

You probably know this, so this is just for general info, but surest way to test starter is set handbrake, tranny in park, (neutral, depress clutch if manual), turn ignition to on (not start), crawl...

Here is a way to do the simplest "fake it full" mod, without cutting anything. It's all reversible in case you want to do something else. You'll be making yourself your very own plug for the harness...

That was a great post with a ton of information.

It took me multiple reads, getting a spare sensor from the yard and doing some testing on it myself to get my head around it a bit, so I'm going to...

It looks like I need to learn to read, eh? Especially the first paragraph of the first post!

I looked at the wiring diagram and when the switch is in high position it activates the "heater high...

Did you get this fixed yet?

I wonder if they did all this to "fix" a failed resistor. That seems the most likely explanation.
The resistor is inside the blower housing. Taking the blower out is...

That's good to know.
There are quite a few other wheel options with a 60.1mm center bore but a 45mm offset. Our 50 seems to be about as big as it gets. Maybe a *small* decrease in offset is OK on a...

Man, I just love having the power of resurrection.
As mentioned above, Previas originally came with 14 and 15 inch rims. Both were 6" wide with a 50mm offset, a 60.1mm center bore and a 5 x 114.3mm...

The offset of those Nissan wheels looks to be smaller than the Previa. Previa rim offset is 50mm, the 17" wheels of the 350Z I looked up are 30mm. Smaller offset means wheels stick out further by the...

man_btc... thanks so much for transferring the stuff you've been putting on here. Very useful. I tried to insert the file right here as a screen shot for convenience but it came out as another link,...

This is a popular thread and the following post, though not as "all time" as the roller fix, saves a bunch of aggravation simply dealing with that inside door handle. I have a few pet peeves, and...

Since this evolved into a starter problem issue thread here is a link to another one with pics of the internal contacts going bad, for those browsing in the future. The individual contacts cost about...

I have a '91 alltrac mtm. The front shaft is a 2 piece type. Please confirm that only the front portion connecting to the diff is missing. The rear portion connecting to the transfer case is still...

Before I realized this thread existed I started one about replacing the fan switch, and in an effort to contribute I described the center dash disassembly with pics. There is much duplication but I...

My newly purchased '93 5 speed with 214K miles had the same awful noises. One sway bar link had a little play. Replaced both links ... noise substantially reduced but not gone.
I noticed there was a...

I just did this mod on a 93 Previa I recently bought, using the HK0608 bearings, so I took some pics.

It is best to take the door off to do this mod - much less work in the end. Two people is...
