Park aid fault 2016 explorer limited

[k9kappy]

Hi all,
This park aid fault comes up on the navigation screen, and on the side of speedometer, after starting engine, none of the sensors go off, backing up and forward,

How can you tell to if it is in the front or back? I see there is not a fuse,
Just checking to see if this is something I can fix myself,

if only I knew which sensor, believe there are 8 sensors plus front and rear cameras I live up North.. lots of road salt..

warrenty is up.. 47k on the vehicle thanks for any help, and which direction should I go.. cash is tight right now..

You're probably going to need to find someone with a professional grade scan tool to scan the system to determine what sensor or module is triggering the diagnostic message and code. You may be able to measure the impedance across each of the sensors, but that will only guide you some direction if one of the sensors is drastically different from the others. Having access to the appropriate diagnostic tool is the more accurate way to check it out.

ok thanks this is what I thought, Definitely not taking this to my ford dealer, even under warrenty they could not or would not fix an issue.. that is still an issue..
I do know some other mechanics
