I have an EF that I converted obdo-obd1. I am fairly well with wiring but I threw a few codes (the other 2 are wiring problems ), but I also threw an o2 code (CEL 41).

I was told the sensor is good but not positive if it is. I think my wiring is good but not positive (will check).

However I am running a 96-00 Civic header on the motor and where the o2 (blunge) is it is located near the end of the downpipe (near the catylitic convertor) where the o2 sensor on a 92-95 Civic is located on the manifold on a runner.

Will this throw my code since its in the wrong place?

Will it throw a code since I am running just the header (not catylitic converter and no exhaust waiting on parts)? I think this may but wasn't positive.

Thanks,
Shane

 

Which o2 sensor code is it? Bank 1 sensor 1 or bank 1 sensor 2? If it is sensor 2 it's because you don't have a cat.

It is also called an o2 sensor BUNG not blunge, whatever blunge means!

 

HAHA. thats right. when I was writing it I was like man this doesn't look right. Oh well close enough .

Its throughing 4 long and 1 short.. CEL 41. which for obd1 is oxygen heat sensor I believe. And I'm only running 1 o2 sensor. Don't need 2.

Thanks again.

im using a y8 header on my 95 del sol with a z6 and i havent thrown a code ever with the o2 bung near the cat.

 

thanks thats exactly what I was looking/hoping for. So now time to trace wires Yay . Hoping its just wiring and not the freakin sensor!!
