rb20det o2 sensor

i bought a 92 300zx tt o2 sensor the plug was the same i dont know if that one will work or if it sends different signals. i found in teh search that 84-86 200sx o2 sensor will work.bc teh car is runnin super rich. so i just wanted 2 know if i need the 200sx or if teh 300zx will work as well

yeah i bought a TT 300z o2 and its running rich too i was thinking the wiring is wrong but i guess if you have the same problem it must be the o2...

so what did u wind up doing about that

[gawdzilla]

that isn't possible. make sure the wiring is correct first. there is only one signal wire. the other two (+ and ground) are for the heater. you can switch the polarity of those two, it doesn't matter. in fact, you don't even need to wire those 2 in. it will just take your o2 longer on cold starts to start giving readings. all you need to match correctly is the signal wire. if the wiring is right and it still doesn't work, something else is wrong
