I had a CEL couple days ago. And the code is O2 sensor. My car is 1993 honda accord SE (F22a6) with 172K miles on it. How many O2 are they? According to the Haynes manual there is only 1 under the heatshield on the header. But it's wrong I saw it way underneath the car before the cat ( B-pipe??) while I did my oil change way back? So how many? And what kind of brand are you guy recomend?(Denso or NGK). Thanks

Your haynes manual is right about their just being one they just have it listed in the wrong place.

And as for the o2 sensor brand id just get oem

 

Bosh is OEM, I was advised by a Honda tech not to use any other

 

Wrong Honda uses a factory NGK. But you can use an autozone Bosh you if you want. Just to let you know I did not have any luck with an aftermarket one!

 

You can get an OEM one or you can get a bosch one, I got a bosch one for my gf's 96 and we had to replace both. You just need to make sure you splice the wires to the correct factory ones to avoid issues.
