What kind of o2 sensor is this Options

[6gsillyca]

Can anybody tell me what kind of oxygen sensor this is, and what type of car/engine it is used for?

I have a 98 celica chassis with a jdm 93 sw20 3sgte swapped in. I ordered a replacement o2 sensor for a 93 mr2t, figuring the ecu would need a 93 3sgte sensor.

Well my replacement sensor has 4 wires, and the clip has 4 electrical contacts. The one currently installed has 1 wire w/ 1 contact. I searched online, but it looks like the 5sfe uses a 2 wire sensor, so what do I have?

edit:
I did a bit of searching on mr2oc, and it seems that the OEM replacement IS indeed a 4-wire sensor, but there have been a few other members that have 93 jspec 3sgte's that came with 1-wire o2 sensors, so now I'm not sure if I should be looking for...a 1-wire 5sfe sensor or a 1-wire 3sgte sensor. I don't know why toyota would put different sensors between USDM and JDM 3sgte motors though (assuming that the sensors are OEM).

Does anybody have any experience with universal sensors?

okay, I have a little bit of experience with this. The one wire sensor that came with the JDM 3s has toyota part #89465-20180 and denso part #065500-4060. I searched online but could find exact part # both on toyota and denso websites. About a year ago, I bought a bosch equivalent for the US 3sgte which was the 4 wire type. Big mistake, because even after converting it to run as 4 wire or heated sensor, it was giving me a really bad mpg. One problem with the bosch sensor is that the probe that goes into the downpipe is just too short. So last month, I went searching again, this time on denso website and found one that is very close to the original one and the part# is 234-1057. it is still a little smaller that the OEM one mainly from the flange up but from the flange down (the probe itself) is still identical. I had just installed it and noticed a big improvement in mpg over the bosch sensor. The website I got mine from is www.densoproducts.com and you can type in the denso part number to look at the one I currently have on. The only word of advice is to stay away from the bosch type and try to get a denso one that is as close as possible to your current jdm one.
good luck.
