so I converted my si wiring harness to obd1 and I was wondering whether I use the one wire o2 sensor from my si harness or do I use the 4 wire o2 from my obd1 wiring harness?

thanx alot for any help!

 

if you use an OBD-1 ECU than a 92-95 Civic o2 sensor is the one you want (NOT THE VX one as it is a 5-wire OR the CX which is a 1-wire)

I wonder if you could use the CX, its 1-wire . but no stick with the 4-wire o2 sensor found in 92-95 Honda's. I think you can use jsut about any.

what u talkin bout?

 

got to autozone and buy a bosch 02 sensor....for 69.00 for a 1994 integra GsR....its a good 02 sensor and really accurate

 

and you use the 4 wire from the obd1 harness because im pretty sure the obd1 ecu isnt going to send a signal to your one wire obd0 02 sensor....itll send the signal to the 4 wire...and no 02 will be there so you will be throwing code 41 all day..and running a little extra rich

 

Well the ecu doesn't really send the signal, rather it recieves the voltage, but anyway... With the 1-wire sensor, the ecu will cry about an O2 heater malfunction. That's the only purpose of the 4 wire sensor, to add the header.

You can use a single wire sensor with the OBD1 computer (like the CX) by chipping the ecu, but then you have an unheated sensor really far from the motor, and it will get clogged and die in no time.

What are YOU talking about ?

 

4 wire o2, i just got done converting my rex and it was so easy and so worth the time and money.

 

I used the four wire obd1 o2 thats what the rywire guys said and I think its still spitting the o2 code... If anyone knows what codes 1 5 and 6 are that would help I tried to search but I didn't find much useful stuff to tell you the truth I didn't understand what some of the people were saying...

 

wtf, man now im really confused, im in need of some info.

how do i wire my 4 wire 02 censor to my harness? sorry dont mean to jack the thread but anything is useful
