Thanks. I'll give that a try.

No. How do I do that?

I replaced what I thought was the right O2 sensor a few weeks ago but the VSC light and CEL light are still on. SO... I got to the local Toyota dealership as the Lexus dealership is more than 2 hours away. They tell me the "bank 1 sensor 1" is bad and want $330 to replace it in about in hour. The sensor I replaced is the one right in front and easy to reach. I thought this one was "bank 1 sensor1". I guess I was wrong. Any suggestions and what part number should I be looking for?
