What is Oxygen sensor part number?

[mazen222]

I have the P0135 code and can notice that my car is burning more fuel.

What is the part number of the oxygen senor? i think its the one in the rear

[QuickSEV6]

I happen to have one and I'm willing to sell it.

Part # 89465-06020

A long time ago, I had a local guy, custom make me an exhaust system. He failed miserably. Another mechanic told me that he thinks the guy messed up my rear oxygen sensor. So, I went to the dealer and told him I wanted another one. I think it cost me about $400.
I never installed it. I figured I'll eventually get a NEW exhaust put on and the new guy can figure out any problems. -I'm not entirely sure the O2 sensor is my problem.
So, I still have the rear oxygen sensor, unused for a gen 1 Solara.

Since I've already sold my LSD, I'm willing to sell more.

Let me know if you are interested.
