Do you even have a secondary O2 sensor?

You might need a new one if you do.

 

I'm reffering the car in the pic.
Its a 99 civic SI.

 

I realize that.

But if I remember correctly, its a stolen recovery, right? Thieves steal stupid crap like that all the time. You may not even have one.

 

aaaa
you're a step ahead of me.
yeah its a theft recory, you can see no side view mirror, they got stolen as well.

I know of only one sensor, which is on the header, which sensor is it refereing to second sensory. Where is the location of that??

 

It should be right around the catalytic converter.

 

right on the cat

 

Thanks Fowler, and 95 ex coupe.

I will tackle that tomorrow.
