6G Celicas Forums

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?
