Help, i'm getting cel code 41(o2), i have a 92 cx with a 2nd gen b16a w/ p28 ericks racing ecu. i'm using my stock harness and i notice that theres only 1 wire for the o2. how do i fix that? thanks

1) if i use a ex/si 5th gen civic harness, will it fit?
2) is there a way i can connect a 4 wire o2 sensor to the cx harness?
3) will CEL 41 affect my cars performance?

 

1 wire o2 sensor? you need the 4 wire o2 sensor

 

use a dx harness or ex. if you need it i have it. but you can also hardwire the 1 wire o2 if you want

 

Just add the needed pins to the ecu harness and connect them to a four wire o2......

 

how do you add the wires to the harness?? any diagrams

 

I went to the salvage yard and pulled an O2 sensor plug from an Accord, as they use 4 wire O2 sensors. Then I wired that baby up to my harness and all was well in emissions land, well except that I can't seem to pass emissions. HTH!!
