Nothing really, I had just decided I wanted to switch out the sensor. I thought it had something to do with another code I was getting and it did not. Make sure you get an OEM sensor if you do plan on doing this.
It actually was not bad just beat up like you said. I replaced it with a non-OEM sensor I got from NAPA and that sensor led to a VERY rough idle. So I replaced the old sensor and relearned the crankshaft position on my tuning device and it works perfectly fine now.
