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.Google+

My check engine light was coming on so I took it to a local AutoZone. They read the engine diagnose and told me the code for o2 sensor was coming up. I bought the part for about $150-200 and installed it myself.

Check engine light came on so I went to get it checked out. The machine read that it was my oxygen sensor so I got that problem fix however, a week later the check engine light came back on and it is reading the same thing.

I have had the O2 sensor changed 3 times, but this problem keeps occuring. I am now keeping the same 02 sensor and just dealing with the light.

Yes, it's common. Once one sensor goes the other one goes shortly. It cost me $600 for front one, next day the light went on again, had to get the rear sensor replaced.
