Hello,
My 2010 F150 Lariat back up sensors have failed. Enabling them from the Setup display option does not work. I have listened to each sensor and cannot hear a ticking noise. I'm skeptical they would all stop working at once. I've checked fuse diagram resources and don't find a fuse bank to check for a blown fuse. I'm about ready to take it to a dealer although I dread doing so.
You will need to scan the truck. It probably has body codes and those generally wont turn on the CEL. There is a whole list of diag steps but they are very specific to a code and symptom not just they don't work. Here are couple wiring diagrams if you want to do some test light probing.
I pulled the codes. It returned U0159. My scan tool said it was either a wiring issue or the Parking Assist Control Module needs replacing. I think I will try and replace the parking assist module if I can find it and get to it. I'm not sure what it looks like or where it is located on a 2010 F-150 Lariat.
I pulled the module. It is FoMoCo 9l3t-15t850-ab. It seems it is no longer made. Checking to see if I can find one. They seem to be scarce. I wish I could find a new one from Ford.

I have read that when parts get updated, they usually change the part number. Check for that module on a newer year F150 and see if it uses a part number that replaces the part number from your truck.
