WTB NB Rear O2 Sensor
 

Looking for a rear O2 sensor for my MSM. I lost the original that was removed when I went to MS, and I have emissions coming up later this year.

Obviously, I'm looking for a functioning part so I don't have a CEL after I go back to the stock ECU for the inspection. Let me know what you've got.

I believe I have one, I bought a car in pieces in a box so i'm not sure if its front or rear but its from an 2004 mazdaspeed. I'd give it to you free if you pay shipping! Can you post a connector pic and estimated length?

Connector is 4 pin in a square pattern. I took a photo of the front one, but rear should be the same (pretty sure the harness end of it is under the seat and carpet, from memory).

It's about 3 feet long and had a grommet integrated to the wire to pass through the body, and at least 1 P-clamp to hang the wire along the run of the exhaust pipe.

Thanks!

The one I have is exactly 24" length in with with heat shielding wrap on it. It has the same connector though. If you think it'll work I'll box it up and send it for shipping costs? Like 7-10$?

Based upon the length, I don't think it will work. I'm pretty sure that's the front sensor. Thanks though.

Bump

Still looking for one of these

Is it the same part as a standard NB2?
