    While reattaching the front splash guard, we found this sensor hanging down. There are only 2 wires going to it and no moving parts, so I'm thinking it's a magnetic sensor for something. We tried placing steel objects and magnets on it and taking them away while the car is running and it didn't trigger any warning lights. For mounting, it just seems to clip onto the edge of something. Any ideas on what it is and/or where it clips to?

    If we are talking a Gen III Prius, there will be a similar sensor located on the 12V battery positive terminal block under the trunk cover near the spare tire in the right-rear corner of the car. Another mystery, your avatar says Gen I Prius and you are posting in the Gen III Prius section. Working on someone else's Gen III, or your car is a 2012 (typo)?

    There's a square hole in the center core support that goes from the top upper core support to the bottom there's a square hole down there at the bottom that this piece pushes into keeping the sensor facing forward into the wind as the car is being pushed forward
