Flat Spin

Disconnect the negative battery terminal for about 10 minutes. Then jump in the driver seat and pump the brake pedal 10 times. Wait about another 10 minutes and then reattach the negative battery terminal. That should clear the cel. If it comes back, then you do have an issue yet.

Thanks. I'll give that a try.

Did you clear the ECU after you replaced the sensor?

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?
