CA 3 wire 02 sensor part number???

[damesta]

Does anyone know what it crossreferences with it? The number in the crossover thread is for the single wire 02. Thanks

i've jsut used a generic 3wire lambda and hooked it into the existing plug.

That said nissan prices are like £100 ($185) here, when the generic one is abotu $50.

I'll see if I can find a part# and any cross-refs if you want when I get home but it'll be ~8.5 hrs

Euro part# is 22690-39F00; this doesn't appear in US parts catalog. very likely other part #'s can interchange as there's not much variation in the sensors, but I'm not really sure of whether or not it's the case on this.

just go get a bosch 3wire universal for a nissan, check 200sx turbos , sentras . i forget what car its from but it works

1990-1996 300zx is the same, thats what I am using.

but I also used a universal one with 3 wires on another engine, bit cheaper.

Allright, one more question, I picked up a bosch 3 wire o2 sensor today. I have no idea what its from, I just found one that fit the o2 bung on my turbo extension, everyone tells me that all 3 wire o2's are the same so I hope this is allright. Anyway, it has one black wire and 2 white wires? Any suggestions on how to wire this up, or on a good way to test and see which wire goes where? I would kinda like to not short out the brand new sensor, lol. Thanks for the help.

The two white wires are you positive and negative, it doesn't matter which white wire is 12volts and which one is the ground, the black wire is your signal wire goes to your ecu and to the tach

I used this type of O2 before.

:withstupidWhites are your heater (not polarity sensitive), Black is your sensor lead.

[damesta]

So as far as matching these up with the wires on the existing harness plug, which are black, white and brown, what would go to what? My guess would be the 2 white wires on the 02 go to the black and white on the harness and the black one on the 02 goes to the brown one on the harness. Is this correct?

[Jezz_s13]

if it's the same config as a UK CA harness then the centre wire (filthy white on my car) is the signal. i have brown and blue for the others.

you could look at the ECU pin out and use a continuity tester to be sure.

[damesta]

Yeah, now that I think about it, the white one is the shielded wire so it must be the signal.

[Jezz_s13]

yep, I hacked into it near to the ECU for my AFR gauge, it was deffo shielded.

cut the plug of your bad O2 Sensor, Hook the red wire on the plug to one white on the o2 sensor, the black on the plug to the other white on the O2 sensorThe white on the plug goes to the black on the O2 sensor
