I have just acquired a replacement lambda sensor, in an attempt to smooth out a lumpy idle.

I removed my old sensor the other day, and here it is:


Now, my problem is, I buggered up the plug a little bit and as a result some of the wires popped out. I think I got them back in the right holes, but I would appreciate if someone could help me out and confirm whether or not I've got it right.



Finally, this is a pic of my new replacement sensor.


As you can see, the plug is different, although the wires are the same colour. Am I right in thinking that the black wire is for the sensor, and the 2 white wires are for the lambda heater?

Is the previous connector correct? Can I just solder (or crimp) the black->black and white->white wires together? I understand that they're a pig to solder as they are stainless steel.

Thanks in advance.

I've seen that, thanks, but that doesn't answer my question.

I need to know

a) are the wires in the old O2 sensor in their right holes in the adapter
b) Can I solder black -> black, white-> white?

(thanks for taking the time to reply, though)

Sorry BuRR, I don't know. I'm sure I've seen the wiring details on here before though.

Can I ask you a question?

What's the part# of your original sensor (Scooby one and the Bosch one if known) and where did you get the new sensor?

Cant help you with the wiring, but you are right, they are stainless and will not solder successfully, at least my older sensor, for the MY94 was anyway. Crimping is the only way.

Steve, if you look at the connector on the loom (on the car) you will be able to match it up. The signal wire's connector is copper whereas the heater wire connectors are steel.
If you look into the connector on the car you will see what i mean.
The heater wires can go any way round so just make sure the signal wire(black) goes to the copper Plug and the two white wires go to the silver plugs.

Cheers!

btw... if you see a large plume of smoke over Wakefield tonight, you know I got it wrong

Hi I changed my O2 sensor today, I bought a subaru part so it was identical wiring to the one that came off. I also did it because of rough idle & the car sometimes stalling. I also changed the MAF sensor at the same time. One of them worked because on a quick test run the idle was rock steady and it never threatened to stall.
Hope it works for you to.

It will

We diagnosed a faulty/failing Lambda sensor, as the readings were very erratic on WOT

And a MAF had previously been tried, but made no difference

The replacement item's part number is L300

The original item's part number (the number embossed onto the body of the sensor is LIC. BOSCH A24-A71 C28 87270
