I dont have an o2 sensor because me ecu doesnt recgonize one, but i need one simply for a AFR gauge, so with that said will a 1 wire o2 bosch o2 sensor suffice?

 

yes it should. My friend has a one wire on his 98 subabru gl-10. His air fuel gauge works fine.

 

Yes it will work but one word of warning:

The single wire O2 sensor does not have an internal heater and relies on heat from the exhaust manifold. This type of sensor needs to be placed VERY CLOSE to the exhaust ports, in order to work. (about 12 inches away max)

Hope this helps.

 

What o2 sensors are heated then? And How do they get heated? My ECU doesnt recgonize one

 

bump going out in 10 minutes to get the o2 sensor

 

Will a heated o2 sensor work if my ECU isn't chipped to recgonize an o2 sensor? Will I just need a 1 wire in that case?

 

Yes a heated sensor will work but you will have to wire 12v supply to the heater on the sensor.

The heated sensor made by NTK is a 4 wire type used in most hondas.

The two WHITE wires are the heater wires
The GREY wire is the sense wire and the BLACK wire is the ground.

Best to wire a relay to switch +12v across the two WHITE wires when the ignition is switched ON.
