1996 Saab 2.0L Turbo
Car has had code (P0133) once at around 59,000 miles and once as of 70,000 (last week).
The car drives great, it shows no signs of anything off.
I don't want to replace a sensor if it is fine, but I am thinking it went bad with age.

I've heard of O2 sensor becoming contaminated(touched with oily hands or water). I believe that causes them to fail sooner or read incorrectly. But they also aren't supposed to last a very long time. Replacing the sensor now wouldn't hurt, but maybe you should take it to a dealership to make sure that the sensor is the real problem.

Probably, this is true. Sometimes what happens here is that the idle air control system or pcv system needs to be examined and cleaned out. The oxygen sensor is nothing more than an electronic nose that sniffs out the amount of O2 in your exhaust and then send signals to your car's computer system to make fine tuning adjustments to your fuel injection system. At this age, chances are that there are deposits on the O2 sensor that are limiting it's proper functions. I hope you are using fuels that have high detergent factors (like Mobil Exxon or Chevron) These fuels tend to keep O2 sensors cleaner and help them to last longer. Also, remove your spark plugs to look for signs of carbon build up or fuel fouling, or just gap changes from age. These also will affect how well the O2 sensor does it's job. Make sure that your throttle body and any vaccum ports on it are factory show room clean. Dirt is always the enemy here. This. also will through off O2 functions. Good Luck!!!

I had to replace the sensor on my both of my cars. So its best to do it while your car is in good running shape, than to be stranded somewhere, wishing you had went ahead and changed it when you had the money and time.

Do yourself a favor and DO NOT go to Pep Boys. They ripped me off big time when i needed my oxygen sensors replaced and still never fixed the problem.

replace the sensor before your car breaks down in the middle of no where and it will leave you walking for miles.....

yes, it happens to all cars. 70k is not unreasonable for the 02 sensor to fail

matters where you live.. if you live somewhere with heavy smog.. could be it is failing.. then you should replace it asap.. could be the age of the vehicle or issues with the computer gadgetry

They have 100% failure rate, eventually. It's consumable.
