Hope this is the right forum.... Alright I was driving my 99 Integra in the snow the otherday and my CEL kept flashing, It stayed on steady after about 3 hours and I reset the Ecu and it went away for a few days then it came back on steady. I went to Auto zone to read the code and the guy said the o2 sensor in the cat is bad. Ive searched for the how to on changing it with a universal but all I found was how to swap oem 4 wire o2 to universal 4 wire o2. Problem is I only see 2 wires on the o2 sensor into my cat.....I havent been able to find this in my searches maybe I used the wrong key words or something but Is thea something im not seeing? Im confused as hell ???? I always thought that the o2 sensors had 4 wires and the JDM had 1 wire.

 

bump for me with no answers..........yet........Does anyone know what im talking about?

 

Problem solved........... the day I got my ITR 2.5 collector JDM cat convertor installed and modified to fit the o2 sensor the numb nutts ripped off 2 of the 4 wires while screwing it in.. thanx for the help Juju....
