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?

Well I found this:

and it is a 1-wire pre-cat sensor for a 93 N/A 5sfe

why not try ordering a jdm 93 mr2t oxygen sensor?
i would assume the sensors are different since the jdm ECU's are different from the usdm ECU's.


are they not?

I tried a few different dealers and they were all useless. They gave me different run-around stories of how toyota does not want customers ordering "japanese" parts, and toyota "limits" their database to only include USDM P/N's. One dealer took 10 minutes to find a P/N for a 93 USDM mr2, and when I inquired about the number of wires, I was told I had to order the $300 sensor to find out. I asked him for the P/N and it did not even have the right amount of numbers (post dash was only 4 digits), and he insisted that was all there was to the P/N.


Malecrod, the denso P/N 234-1057 is for a universal 1-wire sensor. I'm not sure what the difference would be between the universal one ($30) and the OE replacement ($60).

What makes a universal sensor different than a OE replacement? Is it worth 2x as much?
