Check Engine Light Due to Failed Oxygen Sensor on Toyota Solara

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.

What will happen to my car if this is not repaired?
2003 Toyota Solara 96,589 mi,
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.

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.

My check engine light went on for a while now. I put the car on the machine to check it and they told me to change my oxygen sensor.

Oxygen sensor needed to be replaced at 60000 miles ...... Check engine light was showing
2007 Toyota Solara 74,000 mi,
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.

Check engine light. Took in for service. Changed the sensor. Problem solved.
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
1999 Toyota Solara 100,000 mi,
have changed the sensor twice in a year and this time was informed my car has 4 oxygen sensors. what do I do.
2002 Toyota Solara 121,000 mi,
I'm being told by the local repair shop that the check engine light is due to a failed downstream oxygen sensor, and that the part is over $100, with the total cost of the repair at $250-ish. I find the price for the new part online ranges from $40 on up. How hard can it be to unplug the old sensor at two ends and plug in the new one?

I just replaced the 2nd oxygen sensor due to check engine light.
2003 Toyota Solara 105,000 mi,
The first time at 105,000 miles, my local mechanic replaced all of the O2 sensors. I don't remember the cost since it was so long ago, but it was a lot (for me anyway). I have not have them replaced this time (yet) (at 170,000 miles). Replacing two of the sensors was estimated at $600. I was told that my gas mileage would be affected, and it has. Was trying to figure out a less expensive way to replace all of them because the first time I was told that when one goes, the others will go as well.
