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?

I'm not sure. My CEL isn't working properly and I have never been able to check codes. Theoretically I should be able to pull them straight from the ECU w/ a test light, but have not actually done that.

I'm searching a cdn autoparts website, and found this; but again it has 2 wires, and one does not even have a flange.

The website lists different (looking) parts for 6gc vert, 6gc hatch/coupe, and N/A mr2.

I found this for a N/A mr2 5sfe. Looks like it should work.
