Buick Chevrolet Reverse Radar Sensor 13332755 PDC Sensor

If your Buick or Chevrolet back-up radar emits false alerts, long continuous beeps, or no response when reversing, after ruling out wiring and module issues, this usually means the rear parking aid probe (PDC eye sensor) is aging or damaged. When functioning normally, it uses ultrasonic waves to accurately detect distances to obstacles behind, and emits graded warnings on the dashboard or buzzer to assist safe parking. This product OEM number is 13332755, compatible with Buick Regal, LaCrosse, GL8 and Chevrolet Cruze, Malibu and other GM platforms. During installation, ensure the probe orientation marking faces up and the installation holes are clean and unobstructed; avoid excessive bending or pinching of the wiring harness.
