Using a Universal O2 Sensor

Thought everyone could use this, as I haven't seen it posted anywhere in the search.

Its a pin-out / wiring diagram for wiring up a universal O2 Sensor i.e. Bosch to your factory harness, worked for me. I refuse to pay $50 for some wire and a connector.

The Toyota 4 Wire diagram that we IS owners use is in the right column, 3rd down.

Also posted over @ with a more thorough diagram.

So if I have a S/C and I have a header and I have a check engine light. The only way to get rid of the check engine is the o2 sim? You said that it only says things are ok and it doesnt affect drivability or performance. What is the right way to take care of this problem?

Bank 2 Sensor 2:
89465-53150 **
I have contacted 2 different Lexus dealers and received two other part #s for the B2S2 sensor: 89465-53120 & 89465-53190. I was also told that the part # above is not the correct one for B2S2.

Has anyone else had trouble with different part numbers? :confused:

Can someone that has never changed their y-pipe sensor look under their car and check out what part # is on there?

^^ on my BFs IS, he had part # 89465-53150 in B2S1 and on the B2S2 he had part # 89465-53190 ....

anyhow, we switched to the megan headers and the B2S1 Got stripped so we put a plug in it instead since it couldnt go into the megan headers (bc its stripped) ...

Since ive been reading and reading about the part numbers and what I need... now im confused... :( he's had a CEL w/a blinking Trac light ever since... I think the CEL was a p0051 which was relating to B2S1 (the one that isnt plugged in) ...

Thank you.

What year is his? I believe that 01 was -53120, and with later years, the number became -53190, or vice versa. What I know is that -53150 is not the original one for y-pipe. It might physically fit and work, but it's not the correct length w/ harness.

I think the original post needs to be updated.
