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.

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.

In both cases failure of original and next unit, was faulty sensor heater element, do not use dealer old stock to replace sensor buy new from CA, from newly produced stock. We feel defect in old sensors and replacements, 3rd one replaced so far same car. purchase parts from rockauto.com if doing job yourself, it is hard to get to sensor is located in rear of engine, but can be seen. This is my 3rd sensor for this car

I bought my 2000 Solara with 113,000 miles on it. Not long after I bought it the check engine light came on. In all honesty I have never wanted to spend the money to have it diagnosed. I now have 264,000 miles on my car, it still runs good, idles great, gets 26mpg and I'm just not going to waste time fixing a sensor that isn't as relaiable as the system it's supposed to monitor. Does anyone know if the computer for this year model really uses oxygen sensor data to adjust the fuel/air ratio? Please don't just arbitrarily say it does without knowing for a fact it does because as I said, my car runs great and gets the mileage it is supposed to get. Thanks!
