TCS code - C1225

So this happened yesterday. I popped the code C1225 - RF Excessive Wheel Speed Variation. Not sure if the context is related to the issue happening but here is some context of what happened right before. I had just finished washing my "new to me" C6Z06 wheels with a pressure washer and made sure to spray well in the wheel dish, cleaning the wheel dish as best as possible. Also, earlier during the evening before the carwash, I accidently when over a speed bump at too high of a speed because I missed seeing the speed bump until the last second (I need to replace my OEM healight bulbs ASAP!). It was a rough impact to say the least, but no visible damage to wheels nor tires. Anyhow, the code didn't really pop up until after the carwash. I clear it and it keeps popping after a couple miles of driving.
Besides the wheel speed sensor, what are other potential causes? And finally, where can I get the sensor and how can I replace it? I'm wondering if this is the sensor that comes already with the bearing assembly.
Thanks.
