O2 Sensor - Taken Apart

[simmiv]

I replace both my O2 Sensors.. I then proceeded to take one of them apart. It has the four wires, with the heater element. If you need a good 12v heating element, it can be taken out and re-used. The normal problem with these is the soot that accumulates and then hardens on the Zirconsensor.

You can see the flakes lying beside it.
