Does anyone know where to find the correct part number for a 2002 JDM STi oxygen sensor? I've looked around and can't seem to find a catelog that would have the right part number. Even better if you can find a link to the part:D

The one that came with my swap started going bad finally and I tried swapping in a WRX sensor, but for some reason it throws a cel. It had a different plug at the end as well, so I ended up splicing in the wires. No matter how I splice it still gives the cell.

It sounds like you put the rear WRX o2 in instead of the front. What color was the loom around the wires? The US 2.0 FRONT o2 sensor is the same as the JDM one.

If you mean the wire shielding, it is white. The wires themselves are white, blue, black, and black. They match up with the wires from the JDM front O2 sensor, but the connector just has different "keys" on it.

I thought the fronts were the same, but I must have choosen the wrong part number when ordering. Would you happen to have the correct part # for the front?

have you contacted subiegal? she works at a dealership, maybe she can shed some light...
