My VSC and CE lights came on so I went to Auto Zone and they said the code is 1150. They told me it was coolant/thermostat. After reading some of the posts on Club Lexus, I'm not sure I trust what I was told. Can someone help me with what that code means and what I should do about it? Thanks!

Bank 2 Sensor 1 (the one by the radiator). Denso/OE for the part, NO aftermarket. https://www.clublexus.com/forums/rx-...el-sensor.html

Ive had this code a couple times on our 01 RX300 with 225k miles and each time pulled the O2 sensor out, cleaned with electronic cleaner and wire brushed and put back and code goes away.
