284385HK6C Nissan SENSOR ASSY, Price: 615.21$, Weight: 0.7kg

OEM Bumper Ultrasonic Detector for Nissan ?

This precision proximity sensor sits in the front or rear bumper and talks to the parking aid system. It helps you judge distance to walls, posts, and other cars, giving clear beeps or screen prompts. Built to factory spec, it restores quiet, accurate guidance and keeps your vehicle looking original.

Why it’s needed ?️

City driving and tight garages demand reliable parking support. A healthy sensor prevents scuffs, saves time, and reduces driver stress. It also keeps safety features working as designed.

How it works ?

The unit sends ultrasonic pulses, then listens for the echo. The control module measures return time to calculate distance. Sealed electronics, an O-ring, and a formed face ensure correct beam pattern and water protection. It links through the harness to the ECU via CAN for fast, stable data.

What happens if it’s broken ⚠️

Common signs: constant tone, no beeps at all, random false alerts, or a “Parking Sensor Fault” message. You may lose auto brake while reversing on some models, risk bumper damage, and store fault codes. Electrical shorts can also drain the battery over time.

Fitment & install tips ?

• Match color and angle; keep the “UP” mark oriented correctly.
• Do not paint the sensing face; overspray kills accuracy.
• Clean the seat, replace the grommet, and check the clip. Use dielectric grease on the connector.
• After install, run a parking aid test or calibration if the manual calls for it.

Care for long life ✅

Keep the bumper area clean. Avoid high-pressure spray directly on the sensor. In winter, clear ice and road salt. Choose genuine-grade parts for stable readings and long service.
