Gen III o2 sensor replacement? Options

[match220]

I've been calling around about the stock o2 sensor in the Gen III 3sgte. I can't get anyone to cross reference the numbers I pulled from the parts reference list, so it looks like it's not available on any other toyota's produced in the US unless it's under a different part number. Toyota uses the same flange-style o2 sensor on the 5sfe, and there is also the link below from ebay. I'm running an Autronic EMS in my celica, so I can connect any o2 sensor. The holes to bolt it in are elongated, anyone know if this one will work? Or if any of the universal bungs on ebay will work. Since it is cheap, my only concern is it warping from the heat. Since I have the autronic, I can run a 4 wire heated o2 sensor instead of the stock two wire one, so I would like to go with the bung option. Anyone know if it fits?

plus I just got back from looking at the o2 sensor book at napa. They have universal flange style o2 sensors with different size flanges. The ones I noticed were labeled 54mm and 44mm, AND they are 4 wire just like I want! Yay! Now I just need to go over to my car and do some measuring!

for 120$ you can buy a UEGO wideband gauge that simulates narrowband...

I already have a wideband with it's own gauge. It's separate from the EMS. Now that I think about it I've never looked into if the autronic can handle a wideband o2 before. I know I can get a cheap universal o2 sensor for $30. I just need the flange.

you can get one from a 93 alltrac.
they are the same.
but since your on a standalone, i would go 2 wire and save $.

That's good to know, I'll just go with a 4 wire though. I can get the bung adapter to adapt to the screw in style o2 sensors for under $10 and a cheap universal o2 sensor would be about $30. Unless I can get a universal o2 sensor with 4 wires that has the flange on it to fit the car.

Just picked up the 4-wire o2 sensor. Denso brand, napa part number 234-4050. It's a universal o2 sensor for the 93 celica all-trac. I mic'd everything this morning before I went to napa, the measurements all match, I'll put it on the next time I go to the car.
