Parking Aid Sensors
WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The parking aid sensors are wide beam ultrasonic sensors. The sensors continuously send out ultrasonic signals to detect objects and communicate the information back to the PAM. The PAM supplies the ultrasonic sensors with voltage and ground from a common source, and monitors the signal return circuit from each sensor.
Only objects that reflect a sufficient amount of sound waves are detected by the parking aid sensors. The surface properties, size and composition of an object affect the ability of the parking aid system to detect the object.
Other things which affect sensor operation are:
- Incorrect sensor alignment or installation
- Dirt or ice covered sensors
- Heavy rain, or snow
