  • 86na o2 - repost from zzz.com

    for all who don't know I need a titania in my 87na chassis running 87t ecu without a turbo (until after emissions)

    anyway I haven't had luck finding conclusively from any parts sites... first thing is it looks like the big bung but the 86 is a weird year, it is a 3-wire and pretty sure it's both heated and the titania, the part number almost correlates to their z32 o2 part# ... the last bit is off only

    this is the number stamped in it: "0 258 003 276" with "LSH 24" at the top, and it has 3 wires: white-black-white

    assuming it will work, I checked my 87t o2 in the turbo, and it has 4 wires... so this is messing me up, I assume I can in fact use a 3-wire o2 instead of the 4-wire o2, this sensor is brand new

    so how do I wire it up, black to ecu, and both the whites get battery? and I will have to move some pins in the ecu harness right...?



    (I went and did some work and hours later still nothing...)

    Heated titania should have 4 wires. Titania alters a voltage reference.
    1. Reference
    2. signal back
    3. + to heater
    4. - from heater

    The zirconiums are the ones that create there own voltage, so a heated Zirc. should have 3 wires.
    1. Signal back
    2. + to heater
    3. - from heater

    Oh, and if my titania is still good, i may be able to send it to you.

    Terrible idea putting those wheels on...

            so the middle wire is black the outer ones are white, the black would be the output and the whites are 12v and ground in any order....?
