Standard Ignition PPS170 front inner parking aid sensor for the 2019-2022 Toyota Prius and other vehicles detects objects near the bumper for the parking assist system.
Parking assist warnings that cut out, beep with nothing nearby or show a sensor fault message can mean the sensor is damaged. Wiring, a connector, or dirt and ice on the sensor face can be behind these signs too, so track down the cause before buying a sensor. This listing is one sensor; the 2019-2022 Toyota Prius takes two.
The 2019-2022 Toyota Prius, 2019-2022 Toyota Prius AWD-e and 2017-2022 Toyota Prius Prime all take this sensor, and so do many other Toyota and Lexus models. Open the "Vehicles it fits" section to check your exact model and engine.
