So, my check engine light is on and I can the code to be a low voltage issue with my downstream oxygen sensor. I didn't feel like trying to get the equipment to test the O2, so I just decided to replace it. Jacked the car up, put the jack stands in, got under there and that SOB was rusted tight onto the catalytic converter. That mofo wasn't budging. So I went through the processes of free a rusted component. I cleaned it with a wire brush, tapped it with a hammer, tried jiggling it back and forth. Well, on one of my taps with the hammer, it must of been too hard, because I snapped the o2 sensor in half... So I have a rusted ass bottom section of a o2 sensor sticking out the cat. I guess I can get a closed end wrench on it now, but I soaked it with penetrating oil to free the rust hopefully over night. Will try again tomorrow, I ran out of sunlight for today.

tap the casing, not the end of the sensor. Hopefully replacing the sensor fixes it, and you don't have to rewire it(being a 'low voltage" thing with rusted out bottoms). Try not to "tap" a hole in the catalytic converter, those are a bit more expensive to replace.
