My ecu is a p06, what o2 sensor do i need? the engine harness only has 1 wire for my o2 sensor but the o2 sensor in the manifold is a 4 wire. Do I need to get a 1 wire o2 sensor so it just plugs in or do i need to hard wire in the 4 wire o2 sensor for it to work properly?

 

It sounds like you have a cx not a dx or someone swaped in a cx wire harness

 

Yeah sounds like you have a cx. I had this problem and just ended up buying a 4wire O2 harness and wiring it directly into the ECU. It worked great.

 

I have a cx as well but with a p28 ECU and I am running a 4 wire o2 wired directly to the ECU.

 

There is a wire that needs to go to a plug that has a wire for the injectors, iacv, and purge selenoid, the wiring diagram i was looking at says to add one of the wires from the o2 sensor to this plug, did you end up running a wire here as well, or where did you run the 2 wires that do not got back to ecu?

 

i just did a swap on my 95 hatch that had a cx (d15b8) motor and harness to a dx motor with cx harness and am running a p06 ecu. i had to rewire in a 4 wire but only took about 20 mins. These are the links i used:

i spent hours researching so let me know if you need any help

 

After hours and hours of digging and looking and researching this is what I came up with. Car is a 92 DX Hatch, the engine harness that was sold to me was for a CX (1 wire o2 sensor) problem should be solved by purchasing a proper engine harness for my car and then we will be golden. From what I have found and been told anyhow

 

you can switch to a dx harness or wire it your self using the links i provided or i could take pics of how i did it
