Default one wire o2 sensor

I have a b16 swap, and apparently the civic cx has a 1 wire o2 sensor, and the b16 needs the 4 wire? How bad is it that I am drivin around without the 4 wire, and which should i replace it with if i need to? Im not throwing a cel...

Hmm that's really strange your not throwing any codes, You should be throwing o2 codes since It's supposed to have a heater. If your not though it's no biggie, It's problby running just fine. Are you using a chipped P-28 ecu? Cuz the o2 sensor needs depend on the ecu not the motor.

Tha'ts bizarre, have you driven this car for more than one hour at a time yet? I know with my Chipped P28 ecu sometimes it takes a looong time for hte CEL to come on.

I'm almost sure they did take out the bulb, Try disconnecting something and see if it throws a code. If it's just a bulb it won't be so bad, if it's a cut wire it could be a Pain In The butt to find unless it's right by the ECU .

BTW Right now my o2 sensor isn't plugged in and I get stumbling, it 8 cycles (fires every 4th revolution ) and gets HORRIBLE gas mileage. well like horrible for a civic, i mean it's like suv mileage. I think what happens is either the ECU gives it lotsa gas cuz the o2 sensor isn't sending valid info so it plays it safe, or else it's in it's safe mode.

Is it this wire?

A13-MIL MIL (check engine light) Blu/wht

should connect there.
