Strange oxygen sensor\lambda sonda ..., 3SGE 6 gen Options

[cyprus_gt]

Hello
so i was thinking to change my oxygen sensor but when i disconect it from my car i was surpised...its look like no other sensor that i've been seen before on the shops!
Also it is strange that she stay after the catalyst?





i thing maybe this is "exhaust gas temperature sensor" what do you thing?
i have only this sensor under my car

If someone have info please write it here
thanks

Cheers

p.s.
the car is JDM Celica GT st202 1994 year with 3SGE engine !

p.s.
i know its easy to order from Toyota but it cost 200 euro..WTF

this is EGT ,

lambda should be in Y-pipe before catalyst

I found three part numbers for it on toyodiy (which cover ST202 & ST205)

89465-20580
89465-20620
89465-29695

Thanks man
i've just check and saw the lambda sensor on the Y-pipe so will see how many wires have and will order some universal becouse the original from Toyota is very expensive!
btw. this EGT sensor is need to be changed on some km. or years?
thanks
