4 PIN 02 sensors.

[Lori Carlyle]

Does anyone know what wires they attach to the loom?

While I'm off work I wanna get these wired up, and I can't read a wiring diagram for s---.

I've found these here:

This reads to me that, loom side of things are:

Red\Blue (R\L)
Black\White (B\W)
Black (B)


The 02 sensors I have are these details (4Wires)

Black = Signal.
Gray = Ground.
White x2 = Heater.

But which ones connect to which?

Why are you trying to wire it in? Did you buy a cheap o2 sensor that needs to be wired in?

To answer your questions..

They kinda need to be wired in.
Do higher quality ones work on some kind of wireless?

That's the two I have, I could have got them with the loom connector attached, but their over twice the price.

theres a reason they are twice the price, buy the denso ones that are wired with the socket. The other sensors are generics that are usually from low quality control runs, hence why they fail more often.

What he said, just buy Denso 02 sensor, you can find them reasonably priced on ebay.

Will do in the future, but I can use these two sensors until the car hits the road, since I won't be chopping up the engine loom.

Anyone answer the original question?

The chart 3/4 of the way down the page http://www.aa1car.com/library/o2sensor.htm that's shows you what you need to know. Black;Signal, Grey;Ground, White (X2);Heater. Because the heater on the O2 sensor can be wired either way both wires are the same.

The on line manual will show you which wire on the car is for which. So BW and B are for the heater and looks like RL (red/blue) is signal. Your forth wire would go to the Grey on the sensor.

Did I get this right, lol.

[Lori Carlyle]

That's where I got the details for the sensors

I took a look today, but my loom colors are completely different, as per normal

Sometimes, I wish Mazda would just keep this stuff the same across the range, how hard is it to order more of the same wire


Thanks Daninski.

DJmaro is going to look at his in the morning. Can be closed.
