I have a 94 civic cx with a JDM B16A i recently swaped in. I have a P30 ecu and i used the cx harness to wire the motor. Its a 96 model motor if that makes a difference. I have gotten all my problem codes fixed but the ecu will not take my O2 sensor. I currently have a one wire o2 sensor do i need to purchase a 4 wire sensor? Any suggestions are appreciated.

Nobody Knows? :banghead:

Yes you need the 4 wire sensor, and they arent cheap from honda ...

Yes, you HAVE to have the four wire o2 since the P30 looks for a four wire o2.

I appreciate the info :biggrin:
