92 22RE Problem when warmed up.

[buckspooker]

Awesome site. My 92 22RE will start when cold but shuts off when it warms up and wont restart until it cools back down. Any advice?

The oxygen sensor is replaced for free in the USA only when the vehicle reaches it's first 80 000 miles regardless of the age & number of owners as stated in the factory owner's manual in the maintenance section,some Toyota dealerships are reluctant to replace it for free if that happens contact the Toyota regional head office for your region where they will give your local dealership 48 hours to comply.
On average the oxygen sensors should be replaced every 6 years or 100 000 miles or so which ever comes first as stated in the owner's manual,warranty booklet and factory service manual.

Symptoms of a bad o2 sensor are poor gas mileage,hesistation in acceleration,worse emmissions,and in severe cases after the stat opens the engine can no longer maintain stable 750 rpm (with manual 5 spd tranny) idle and the engine begins to stall.
The 02 sensor is designed to function once the vehicle has warmed up which is about after 10 minutes where the thermostat begins to open at 190 or 195 degrees Ferenheit depending on thermostat then the vehicles ECU system enters what they call a "closed loop system" then the exhaust manifold's temperature reaches 400 degree Ferenheit (I think)that's where the sensor starts to do it's job which is usually when the thermostat first opens up then the oxygen sensor senses the ratio of air to fuel and sends a signal back to the ECU then ECU compensates by increasing or decrease the open time for the fuel injectors to pump fuel.So usually the problem of stalling shows up after about 10 minutes of driving or so.many folks think that the o2 sensor is bad but an exhaust leak can cause excess oxygen to enter the exhaust system thereby fooling the sensor into thinking there is too much oxygen,there are other problems that could cause it to give false reading such as a vaccuum leak.

If you discover that the o2 sensor is bad and it is not under warranty then from my/others experience/research purchase an o2 sensor in the following order:

1)Toyota (NipponDenso now called Denso)
2)Denso aftermarket (Same as original but sold aftermarket)
3)NTK (oxygen sensor division of NGK)

Note:Toyota has an organized numbering system which dictates that the first 6 digits of their 10 digit (5 digits-5 digits)part numbers represents the part # and the remaining 4 digits dictate country of origin,color code,trim package and so on not in that order as shown in the free Toyota EPC (electronic parts catalog) download at:

Here is a post fellow poster (Todd) who posted it on another 4-Runner/Pickup discussion site about 2 years ago:

"There is a newer version of the EPC available for download.Similar in size to the older version (254MB and 220MB zipped files)I have them on my personal FTP server (not always running), and they are also on another FTP server.

NGK has a powerfull oxygen cross reference software which cross references their different part #'s into either a single,double,triple or a quad wire o2 sensors so you may find 10 or so different part #'s for your 92 pickup and all you have to do is plug those part #'s into:

http://www.1sttoyotaparts.com

and see which one is cheaper I think you will find one for as low as $60.The NGK cross reference software is:

before you replace the oxygen sensor soak the 14 mm brass nuts with any of these deep penetrating oils several times for several hours:

1)PB Blaster
2)Liquid Wrench
3)Kroil Oil
4)Aero Kroil & Sili Kroil
5)Toyota Rust Penetrant or High Performance Penetrating lube
6)Rust Check

the first ones being the best,also if you decide you need new ones here is the Toyota part for the exhaust manifold (brass)nuts # 90179-10175 (14 mm socket)

Oh yeah,I bought a NTK (NGK) oxygen sensor for my 85 4-Runner and it came with a gasket and a genuine made in Japan black plastic tie wrap I don't know if the Toyota or Denso aftermarket ones come with a gasket but ask them before you buy them.

To clean the throttle body remove the air intake hose and examine the intake and throttle body for excessive carbon build if found then buy a can of throttle body cleaner labeled "safe on oxygen sensors,TPS's and catalytic converters" do not use carb cleaner make sure your engine is fully warmed up prior to using as when the throttle body is hot it dissolves the carbon easily and quickly.The labels usually specify to park the vehicle at ground level (0 degrees,no inclination) and have the engine running but I disagree I instead park the vehicle on a hill facing down and shut the engine off and hold a rag below the lip of the throttle body and poor the stuff and use a tooth brush.

Thanks for the repsonse. Ispoke with the dealership and they claim that one of the sensors is bad and that a faulty O2 sensor will never make the engine quit running. So I guess I'll be taking it up there and let them put the diagnostics to it.

[Sidney]

About half of the ECU codes stored on the first & second generation EFI Toyotas don't show a constant blinking check engine light therefore you must pull the ECU codes and auto tranny computer codes to see if a fault is registered.
To pull the ECU codes:

All 1980-1995 and including 1995 EFI equipped vehicle allow you to find engine and related faults by pulling the ECU (computer) codes without the need for a handheld OBDII diagnosis scanner,the sites listed below have the fault codes needed to pull the codes and the instructions on how to do it:

http://autorepair.about.com/library/...bl-dtcs-90.htm

Pulling the ECU codes is the first thing I do to diagnosis a problem thereafter I reset the ECU to see if the same problems show up and if so I then take voltage measurements both with the engine running and not and compare with the factory service manual,I also close the ignition switch after a cold engine and also after a warm engine and compare them with the factory service manual.This technique will completely isolate your problem without having to do trial and error and it is the technique I use when repairing tv's,vcr's,home/car audio.

Any public library in your area would have the Factory service manual,Haynes,Chiltons,Mitchells and Toyota repair books.
There is also free AutoZone service manuals at:

Let us know if you (or the dealer) finds the problem. I think this is a common problem with older Toyota's, but I have not heard of a definite fix. Just bandaids like mine.

[TaCoMa974x4]

lol Damn Sidney got the sites going on!!! cool info man. so the O2 senser cause a ruff idle? the vrummm vrummm thing when idle? mines doing that at 150,000. and u say toyota should change it for free? and how would u contact teh regional office if they did not? cause toyota and the dealer ship both always refuse to give u a regoinal office number

[buckspooker]

Well I took the truck to the dealer. After the diagnostic they said its the distributor. They want 514.00 to put a new one in. So I promptly paid them the 39.95 fee and went to NAPA for a rebuilt one for 165.00 + exchange. I've changed a bunch of em in small block Chevys but this swap will be a new experience. Anything to watch out for or any helpful hints?
Thanks

[canadianbiz]

Hey 'buck", buy a Haynes repair manual for your machine. A good investment if you intend on keeping the vehicle and they are very descriptive.
$39.95 free bux to the dealer just to find out what is wrong. Then they want to rip you $514 for a new distributor. Hope they are right with their diagnosis. Gee, I love my old 86'er, rusty but runs and I dont have all that aircraft electronics in it!!!!

[GeneralBenson]

mine 84 celica does the same things, has trouble starting once the engine is warm. it'll start and then die immediately.

[buckspooker]

Changed the distributor today and ran it up to temperature. It doesn't shut off anymore. Looks like the dealer got it right.

[bkirchner81]

Something doesn't add up.... How could it have been the distributer when the problem is obviously Temperature-related?

My truck has had this exact problem ever since I installed new ceramic-coated headers- well, the gasket that came with this header was useless and was destroyed within weeks, so I took it out and replaced it with some high-temp copper gasket maker (which I heard was the best option anyway). I didn't exactly do a very good job of creating a seal between the head and the header- due to a complete lack of room to work with, whatever. I know this because I can feel and hear air blasting out from this area, obviously.

Now, since reading this post, mostly Sidney's vast knowledge, I am thinking that this is allowing some unwanted oxygen to enter my exhaust and trick my oxygen sensor, which COULD be faulty anyway- But I will redo the gasket-goo job first before purchasing a new OS.

Now, my actual question is, what is all this about toyota part#s and parts catalogues? If I actually need the sensor- can't I just call up one of the many part-distributing shops and say "92 toyota 22-RE, I need an Oxygen sensor" ???

What is this crazyness?

[buckspooker]

I would have never guessed it was the distributor either. While researching for a rebuilt one on-line one of the rebuilders lists "engine shuts off when warmed up and won't restart until cooled off" as a symptom of a faulty distributor. So to me this verified what the dealer claimed so I bought and installed a rebuilt one. I ran it around town town today and got the emission inspection with no problems exept that now the clutch is slipping.
