o2 sensor

[Trigger]

Ok i think this is one of my biggest problems right now. i dont think mine is hooked up right so i need to know something about the wiring. I am having to wire my ok right into the ecu because my harness didn't come with the clip but let me see if i have this right

slot 29 (black) goes to red wire on o2slot 115 (blue) goes to black wire on o2brown wire goes to red wire on o2

am i right or wrong guys?

To my knowledge, most of these engines (not all models though) came equiped with a "one wire" 02 sensor and that wire should go in the # 29 on the ECU.

I had that setup like that but i wasn't sure that is was working right. It kept dumping gas so i figured it wasn;t working but i think that i was running the wrong plugs. I seen in the manual that it used a hot plug and i was using a colder plug. so i am going to be putting thoughs in tomorrow and see if that makes a difference

Your wired wrong. The two red wires are the heater wires for the O2 sensor, the black wire is the actual sensor signal. A black wire and a brown wire need to connect to the red wires (shouldn't matter wich way) and the blue should connect to the black wire. I don't know if putting power to the wrong wires of the O2 would mess it up though...

but i have 1 black wire, one white wire and one red wire. I was looking at my roommates 300z and he has the same o2 as me and on his the white was the sensor wire (slot 29) not sure about the other 2 but i know the white has to go to 29 so now i just need to know which is the power and with is the heater

it doesn't matter. the heater isn't polarity sensitive. the o2 signal only requires one wire. the other 2 are for the heater. Just hook them up and you should be fine.

Is heater operated (+12V) from ECU pin 115? I think that there should be too strong current
