are there suppossed to be two o2 sensors on my jdm b16a..its an obd0...because i only got one on it..no codes or problems...just curious

anybody?

 

If your running the odb0 ecu and its not chipped, yep there are suppose to be 2

what if I got the JDM 4-1? Im only running 1 of the sensors right now, do I really need it? I aint gonna weld up another bung cause I heard stories of them coming up *** up.

Yep you really need it, don't skimp on something like an 02 sensor.

 

Yes you really need the 2 o2 sensors, and you should have 2 bungs welded into the appropriate runners and not use the single bung after the collector.

 

anyone know what the appropriate distance along the runner is to place the 02?

 

10-12 inches from the exhaust port depending on the header on and obd 0 b16a

I've got an AN-R compact and have decided to tap 2 bungs as opposed to trying to split one signal, but its all twisty and crap...so I will try to nail it down to 10-12 inches. They go on the first 2 primaries (drivers side) correct?

 

 

mine is the same way...been running only 1 o2 sensor for a year now no codes and runs fine. Im starting to think the ecu was chipped by the orginal owner. I got it from hmotors though..

 

I've got the obd0 b16a in my civic with a dcsport manifold and i only have 1 O2 sensor and everything works just fine. No cel... and my ecu has not been chipped

I have the same header check this post all the way at the bottom, you want you o2's to read off 1/4 and 2/3 and have the appropriate wires run to the ecu

Alright if you 2 guys are supposedly runnin only 1 of the o2 sensors, then which one is it!, C8 OR C16!?.

 

the primary o2 censor....c16

 

gots_a_sol did the wiring on my engine and he just wired them both wires to the 1 o2 sensor. you can pm him if you need to

 

Hmm thats interesting so you basically run c16 if you only have one 02 sensor?, or if you'r saying you can run both c8 and c16 together into one 02 sensor

 

i quess they are saying spice the wire for the 1 o2 sensor and run it both to c8 c16

 

O yeah yeah, i wasn't thinking straight on that one, of course. Thanks

Whens the last time you hooked up a wideband to your car ? Yes the car might seem to be running fine but unless you know what to look for ( running rich or lean ) you will never no

Do it right the first time, or pay in the long run.

 

seriously do it right it cost me 25 bucks to get the bungs welded up....honda intended there to be 2 sensors, run 2 sensors.... but this brings up a question, many ppl say if u bog, then switch the pins at the ecu, i just switched the o2 sensors themselves. i thought this was the right way to do it cuz u add the 2nd wire at the ecu, and i did it according to hasports directions meaning theres no way i could have switched them up at the ecu, but couldve switched up the sensors themselves. does that make sense?

what do u mean by a wideband??? i got an a/f meter in my a pillar..and it always reads all the way rich...not to mention that my car runs super STINKIN rich...it might have to do with vafc as well but i think its mainly from the single o2 sensor...

u should see the tips of my exhaust..haha its clackened all the way till the end and even around the outside of the tips

Wideband, as in wideband o2 sensor, set you vafc a zero and get both 02 sensors hooked up in the right position and wired correctly, its the only way you will fix the problem
