About 8 months ago my check engine light came on and I took my car to the dealer. They told me that the "passenger side oxygen exhaust sensor" is defective (bent slightly from when I had my accident) and that the repair would cost me over $220.
First question is:
Is there a possibility that this can be fixed (replaced) by me or do I have to have the dealer do it?
Is there a way to just dismiss the error as if nothing is wrong?
Thanks for the advice in advance.

Is it possible to do it yourself? Yes, according to your (or your friends) skill level.
Is it possible to "dismiss the error as if nothing is wrong"? The correct answer is no. While you can "dismiss" anything you want, the oxygen sensor serves a vital function in monitoring how the engine is running. If it is not working correctly, odds are neither will your car.
Yes, there are workarounds that people who remove their catalytic converters and perform other unwise/illegal modifications sometimes use, but it does not change the fact that your engine may not work properly and you will likely fail any emissions testing you may have in your State for Motor Vehicle Inspection (if you have one).
