Just finished my swap and it's throwing a knock sensor code which I double checked the wiring and it seems to be correct.
And it's also throwing cel code 1 which is primary O2 sensor.

what do I need to get it fixed?

 

what car and what harness and ecu are you using? also make sure you have it all wired up right for the knock. as for the O2 it can be anything to wrong wiring or broken wires to bad O2.

Did you use shielded wire with and supply the braided stand wire with a ground to shield out electrical interference's?

What model/year car is the swap in? Some require rewiring of the O2 sensor if they aren't setup for a 4 wire O2 stock.

 

No I just used regular electrical wire. I'll try that though.

It's a 99 GSR swap so obd2a O2 sensors.

 

OH it's on a 97 Civic Hatch.
