How The Backup Sensors Work - Honda Backup Sensors 08V67-SJC-1000-81 Owner's Manual

Backup Sensors
The sensors are ready for operation when the backup sensor switch is turned ON, and the shift lever is moved
to the reverse position.
The sensors operate by emitting ultrasonic waves. They calculate the distance between the rear bumper and
an obstacle by measuring the time the ultrasonic waves take to reach the sensor after being reflected by an
obstacle.
