丰田卡罗拉花冠倒车雷达传感器 89341-33050 泊车电眼探头 精准感应

When your Toyota Corolla/Allion shows reverse radar false alarms, no alarms, or persistent beeping, it indicates aging or damage to the original reverse radar sensors. The sensor, when functioning, uses ultrasonic detection to measure obstacle distance behind and issues graded alerts to aid safe parking. OEM number 89341-33050, compatible with Toyota Corolla and Allion multiple models. Installation notes: insert sensors into bumper at the original positions, ensure harness connectors are clean and firmly engaged to avoid looseness or water ingress causing false alarms.
