Ultrasonic Park Assist Sensor for Toyota Bumper 🚗🛡️

Keep tight spaces stress‑free with this genuine‑spec ultrasonic detector. It restores factory park assist, warns of obstacles, and helps protect paintwork and pedestrians. Designed for seamless fitment in the bumper socket with a sealed O‑ring, it plugs straight into the OE harness and talks to the parking ECU for precise beeps and distance feedback.

Why you need it ✅

If your parking aid is silent, gives random continuous tones, or shows “Park Assist Unavailable,” this sensor is the usual culprit. Replacing it brings back accurate proximity alerts, improves low‑speed safety, and keeps the Intelligent Clearance Sonar functions working as intended.

How it works 🔊

The unit emits high‑frequency sound pulses (ultrasonic) and measures echo time to calculate distance. The controller sends this data to the car’s ECU, which converts it into graduated beeps and display cues. Correct orientation and a clean face are vital for reliable readings.

What happens if it’s broken ⚠️

You may get false alarms, no beeps at all, constant tone, or a system disable message. Tight‑spot maneuvering becomes risky, bumper scuffs increase, and auto braking/clearance functions can be limited.

Fitment tips 🧰

Clip out the old unit, inspect the grommet, seat the new sensor flush with the “UP” mark aligned, and avoid paint or wax on the sensing face. Most cars self‑learn; clear fault codes after install for best results.
