Lexus ES300 Problem Report
Lexus ES300 Check Engine Light Due to Failed Oxygen Sensor
The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.

CEL from rear O2 sensor. Replaced sensor, canceled code, problem fixed. NOTE. almost any CEL on the 2000 300ES will be accompanied by a "traction control off" light. That is a design feature to protect the traction control system. One the 0-2 sensor is replaced and codes canceled, traction control light will go out as well. - illmanners
