I read on here somewhere that the connector for the female side of the O2 sensor was 90980-11028. Turn out at least 1 of the 4 connectors is slightly different in that the connector is keyed differently than that one.

Upstream; Cylinder 4, 5, 6

Anyone have a part number for that?

Ok, so whats the actual problem with the 11028? Cause that part number is for just the plastic housing right and not the complete connector with female pins? Is the connector a different shape?

I only say this because IF you got the complete plug with wires AND housing, you can remove the pins and insert the ones that are already attached to your car.

I'm still checking to see if theres another part number. its possible that since your car is the last of the 2gen, it MAY have an 3gen GS part... Small possibility nonetheless.

The 11028 has a different key than what is on that connector. 11028 has a completely flat key and the one I need to replace has the flat with another piece perpendicular.

I posted a link in my first post so you can see what it looks like.

If you look up the O2 part number on rockauto, previous years used the same part.

I'm so sorry Bruce, I failed you!

I checked most all my sources... I rarely fail to find this kind of stuff! Everything keeps pointing back to the incorrect one you got. Maybe its because its too late I'll check again tomorrow.

I'm stumped

Thanks for trying. Might just have to go down to the dealer to see if he can look something up.

And JUST as I'm about to give up... I run into this:

The plug doesnt match the GS plug because its not the correct one. Refer to post #10

However, this seems to point the opposite problem unless the description in post 10 is backwards and its bosh on the right and denzo on the left.

I wanna go to sleep, but I cant let this go! LoL But I'm not thinking coherently and probably sounding like a moron Lol

Current O2 sensor(original) and female plug on the car has the extra little tab. New O2 sensor I bought which is a Denso also has the little tab.

For future reference for anyone that reads this thread, the part number for the connector I was looking for is 90980-10869.

I went to the dealer and he couldn't find it in the parts lookup so he told me to look at the connector with a magnifier and I found the last 5 digits of the part number.

Again, this is for Upstream; Cylinder 4, 5, 6 also known as Bank 2 sensor 1 and is unique because the connector is near one of the other O2 sensor so you can't misplug them into each other.
