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.

Five years ago, my sensor component failed. The problem was never corrected because I was told by the dealer this problem would not harm the engine.
