Which sensor is this?

My vehicle is a 2015 Volkswagen Passat Wolfsburg edition. I ran over a squirrel the other day on the driver side of my car and it has done some damage to my bumper shield and also a sensor. This is the picture of the wiring harness that the sensor connects to (sorry it was not as clear as I hoped it would be)

It has PA06 and 9805940 written on it, looking that up did not help me much. The check engine light is now also on and throws this code: U0423 and also looking that up did not help. One last thing is the TPS light keeps flashing for a minute and then stops and stays on

The sensor seemed to be connected to something that is by the driver side wheel but I have no idea where it was connected to. Any help would be appreciated

Edit: Just wanted to add that this vehicle is a california emission (not that this matter) And also the fan seems to be always on even from a cold start, wonder if the ECU is doing that as a protection measure. Also that plug has only 2 pins on it so that sensor shouldn’t be that complicated I will take better pictures and post them but would appreciate any help
