The Check Engine Light may come on because a component of the oxygen sensor stops working. Replacement of the failed sensor should correct this concern.

    The "Check Engine" light as well as the "Track Off" and "VSC" lights came on. The Lexus dealership told me the cause was a failed O2 sensor and recommended I replace both front sensors even though only one was faulty. Total $850.00

    Sensor is not working but is fused to the exhaust manifold. Mechanic broke a tool trying to get it off.
    we are now looking at replacing then exhaust manifold. $800 to replace a sensor !

    got this checked out because of the light, and they told me it was a bad sensor that has no effect on how the car runs, but was going to be several hundred dollars to replace, so I didn't get it fixed, but the only problem is that the constant check engine light could be masking another problem.
