Last week I changed the sensor out and all was back to normal. Pretty straight forward. Like three 8mm bolts on each side in the fender well. On the driver's side also two 8mm bolts you should loosen to remove the front part of the inner fender cover. unplug the harness on the driver's side, then there are a three 18mm nuts on each side (total of 6) of the bumper supports (You'll need a wrench for at least 4 of the nuts) . Once you have the bumper off, you can access and remove the cover that holds / covers the sensors. You don't have to take off any bolts, but unsnapping the cover is kind of a pain so use a pick or small screwdriver. On restart, it no longer threw an error message regarding parksense.
