i got a crx b16......i want to get ever thing running right before i start my all motor build. i'm getting the knock sensor code but it running fine but after awhile it goes into limp mode. but the thing thati dont understand is why i'm not getting a o2 sensor code because their is only one sensor hooked up. any suggestions
 
If you are running an obd1 engine the only o2 sensor the ecu is looking for is the precat o2. Did you put an obd0 or obd2 engine into that crx?

You are right about two o2's in the obd0. Each o2 sensor monitors two cylinders from what I have read.
One sensor reads 1&4 and the other reads 2&3.
Are you running a PW0 or PR3 ecu?

I found these pictures. I don't know if they will help you, though.

i got them pictrues my main question is why isnt it throwing a code because i have only one hooked up. thanks. you got any other ideas
 
hmmm...with no secondary o2 it seems like it would throw a code 1 or code 2: defective circuit or/defective or unplugged sensor, depending on which o2 sensor is being read.
