I've accidentally pulled the wires out of the plug connected to the front O2 sensor. I tried jamming them back in but getting a fault light. I have a 2004 2.0X Forester, but I imagine the same sensor, I think it's a Denso, is used on other models. I've got 2xblack, 1xblue/white and 1xwhite on the sensor side and 1xyellow/red, 1xblack, 1xblue/white 1xwhite on the harness side. I tried connecting black to Y/R and matching the other colours but no joy.
Can some kind person tell me how the plug is wired? A photo would be great.

 

Which side have the wires come out of, Sensor side or loom side?

I've got a sensor at home with the same wires out of my old wrx, If it's sensor side I'll get a photo up for you later.

 

Hi,
thanks for your reply.
It was the sensor plug I pulled the wires out off.
Anyway, I managed to get a picture from the Denso website. Connected up accordingly and what do you know, It worked first time. How often does that happen?
Cheers.
