Yup, the first O2 sensor. Part numbers:

GT: 89465-20670
GT-S: 89465-20700

They're not cheap. You shouldn't pay much more than $100 for them. List price is $133.

 

Thanks BlueBomber, i know you always have the knowledge

 

Blue Bomber... when i pulled out mine the part number reads 89465-20690.

Weird.... am i pulling the right sensor?? So where is exactly the other sensor2 located?

Thanks Bomber

 

Interesting, that number doesn't even come up as a Toyota part. The sensor is the one right between the cat and header on the exhaust pipe. It's the only thing there.

 

hmm... well... i got my car as used car... probably the previous owner has put another similar Toyota model's O2 sensor there...

Any idea what would be the Rear O2 sensor part no will be Bomber?

Thanks for your help Bomber

 

That's the O2 sensor for a JDM celica vvtl-i 190bhp. I need one of those for my import but unable to source. Any luck in finding that sensor! Let me know as i want one!
