my setup in my 91 civic si is a jdm obd0 b16 swap i'm get the code for a 2nd o2 sensor i only have one o2 sensor do i have to put another one

the next code i'm getting is for my knock sensor do i have to do u think that because of the 02 sensor i can be getting that code or u think it my knock sensor, if so can i use the knock sesnor off my single vtec swap

 

As far as i know when running the obd0 ecu you do need the second 02
For your knock sensor, check the wiring for it to your ecu, the pin may be different, you can get a chart on hasport. Im not positive on this but its something you can look at.

 

i was told there is something that i can buy to trick the ecu to think there is a 2nd o2 sensor is that true
