other than checking by part numbers which are different, are 4th gen accord and 4th gen h22a o2 sensors the same in terms of signal they provide??? would using a 4th gen accord o2 sensor on the h22a be why it is running rich(i know it normally runs rich but its running richer than the normal rich)???

thanks

 

I was almost positive that most 4 wire honda/ acura o2 sensors are the same. the only difference is the wire length. I have a friend that works at honda an thinks the same thing. No idea why there is such a difference in price.

so you should not ahave a problem running an accord o2 sensor.

I have one question why do you think you are running rich? (flames/ airfuel meter/ smell) just wondering.

 

thats what i was wondering cuz on the 5th gens there are 2 different o2 sensors depending on year and tranny. i ask on a different thread but a mod locked it

 

i am failing the HC part of smog, my o2 % is 0% so i am using all of the oxygen, but i am leaving unburnt fuel, even with lower octane(89) so it is definately running richer than it should be, all sensors are in place(iat, etc..) and i am not throwing any codes, so the only thing that could be making me run so rich is o2 i think, unless one of the IM runners is blocked and no air is getting through which i doubt....

My butterflies werent working for a while I used to throw nice flames out the exhaust between 1st and 2nd and 3rd shifting. I didnt have a cat in. but I did have a resonator and muffler. check to see if your butterflies move if you rev it up from under your hood.

not saying its your answer I just know that my car liked running rich and throw flames when my butterflies werent working.

 

well right now i dont really care about it running rich past 3000rpms, im trying to get smog taken care of which is only 15/25mph and <2000rpms...so butterflies wouldnt matter at that low of speed

 

ttt, anyone whether the signal from 4th gen accord and 4th gen h22a o2 sensors are the same or different???
