Cleaning O2 Sensor?

[noRys]

Is it possible to clean an O2 sensor?

I just upgraded my turbo, exhaust manifold, and O2 housing. I couldn't get my O2 sensor off my old housing. I'm using a used O2 sensor that my friend had. Everything is installed and car runs fine but the check engine light comes and goes. The check engine light is for the O2 sensor.

Anybody ever tried cleaning their O2 sensor or can it even be cleaned without messing up the sensing material inside? If you have cleaned it before with success; what did you used to clean it?

Thanks

In the past, I've used a wire brush to get all the build up off. Then I used a can of compressed air to get any remaining dirt out of it. Didn't have any more issues with the 02 since.

If you're getting a CEL for the O2, this means that the ECU can't see the sensor and it may not be an issue with the sensor itself. Make sure the connectors on the wiring harness and O2 sensor are clean and making a good connection.
