O2 / oxygen sensor interchangable?

[BlitzRacing]

hi guys,

I want to replace a broken (cable broke) 91 3sgte oxgen sensor with one from the 7mgte.

Both single wire configs.. would it work? and the bungs are identical\

thanks you all

[oldcorollas]

yes.......

[Pr0j3kt_SuPrA]

on this topic what are interchangable with the 1jzgte o2 sensor if i remember 3 wire?

[oldcorollas]

any 3 wire

edit: as long as it fits in the hole

My turn...

AE101 GZE, what will fit? I'd rather get one locally for cheap instead of the $250 Toyota want for one.

[oldcorollas]

same number of wires, and as long as it fits in the hole, or you can make an adaptor plate with M18x1.5 thread.

All narrow band sensors range from 0 to 1 volt so as said it doesnt matter too much which one you use .
However the genuine sensors do last longer and from what it seems are more resistant to poisoning but any sensor can be poisoned .

Is there any way to tell the condition of one outside of it being hooked up? I really need one for the cressie but as I am selling it I dont want to fork out for a new one.

cheers

i remember something abotu using a propane/butane torch witha big enough flame to cover the end of sensor, since inside the flame will have some stoich and some rich areas..

should be able to find something (at least on MS site)

thanks oldcorollas.......... no one else seems to know the answer..

there is very little difference in most O2 sensors.
of the narrow band type (1-4 wire)
1 wire is always signal to ECU (and it earths thru exhaust)
2 wire, the second wire is the signals earth
3 wire, 2 wires are heater, 1 is signal, and signal earths thru exhaust
4 wire, 2 wires for heater, 1 wire for signal, 1 wire for signals earth

almost all aftermarket have same M18x1.5 thread. EOM often use plates that are welded to the sensor, to attach to flange.
you can easily get plates with the M18x1.5 thread, to attach aftermarket sensors to the stock flanges.
soldering to the wires to change type of plugs is not always easy.

almost all narrow band sensors have similar output, with no reason not to swap them around

wide band is more complicated and are not usually interchangeable with each other, and never interchangeable with narrow band sensors. (unless you have a driver circuit with a 0-1V output)

pass it on

Do any manufactures use wide band on their production cars?
How do you tell the difference between wide band and narrow band visually?

[TERRA Operative]

I wouldn't expect so. I believe the useable lifetime of a wideband sensor is much shorter than a narrowband.

We only use ours for tuning (Bosh unit I think, with the Microtech box).

[oldcorollas]

honda used the famed NTK. (and later restricted their sale iirc)
VW group uses the Bosch LSU4 (and they are avaible cheep)

I emailed a few EFI specialists a few days ago as I need to replace my Oxygen sensor, and they said as long as it has the same wire configuration, in my case 3 wire It will work, Just be sure to solder the wires up correctly.

So you can goto Auto one and buy a universal one, however some cars have a screw in oxygen sensor, and some such as mine have a flange on the oxygen sensor and 2 bolts are used to hold it in.

Here is some good information on testing oxygen sensors, I followed this guide when testing mine:
