Parking sensors provide an audible warning as your vehicle approaches an obstacle, making tight spaces easier to judge. A professionally fitted aftermarket kit can add useful assistance to cars and vans that did not leave the factory with parking sensors.
How rear parking sensors work
Ultrasonic sensors mounted in the bumper measure the distance to nearby objects. When reverse gear is selected, the control unit activates and a buzzer sounds more quickly as the vehicle gets closer. Sensors are an aid, not a replacement for mirrors, cameras and direct observation.
What installation involves
- Checking the bumper and selecting suitable sensor positions
- Measuring and drilling accurate mounting holes
- Routing and securing the sensor wiring
- Connecting the system to an appropriate reverse signal and earth
- Positioning the buzzer or display
- Testing operation before completion
Bumper shape, reinforcement bars, tow bars and vehicle electronics can affect the installation. Correct positioning is important because sensors mounted too low, too high or at an unsuitable angle may produce unreliable warnings.
Are parking sensors suitable for every vehicle?
Many cars and vans can accept a universal sensor kit, but the vehicle should be assessed first. Some modern lighting circuits require additional consideration, while metal bumpers or unusual bodywork may limit the options. Colour-matched and display-equipped kits may also be available depending on the equipment chosen.
