I noticed today when backing my truck into a parking spot at work that the backup sensors didnt go off and for some reason OFF was lit up on the button but I didnt turn them off and couldnt make them turn on again.

Same thing happened at the gym tonight.

Both times I tried backing up after leaving the truck parked and the sensors worked fine.

What could be the issue? I didnt notice anything obvious and the sensors worked fine yesterday.

It has been raining a bit around here although it was dry this afternoon. Im hoping its nothing too serious and expensive.

 

when mine was doing that i foun i had a blow fuse well actually it was a few blown fuses and it started working after that

 

Mine actually starting working on their own again. No idea what the issue was but theyre working fine now.

 

I had something like that happen to mine I have not had a problem since I took apart all the connections that I could find that connected in any way to the harness containing the wires for back up sensors and put electric terminal grease on them

 

Just had my rear bumper replaced from the idiot that backed into it prior to trading it in, dealer paid for it, but found that 3/4 sensors were broken, but worked, 1 had the wires cut from being pinched, he soldered those back, replaced the sensors, and now, I have a steady OFF lights. I am going to check my fuses tonight, are they all in the cab, or some under the hood? Ill be lucky to get my hood open after hitting my deer.. or shut once I do get it open.

 

Wondering about the fuses too having the same issue.

 

mine did not want to work... it would shut off also ...Ford fixed it under warranty...they replace a bad sensor.

 

I had trouble with the sensors again so I took them apart to clean and grease them and noticed one was broken (came apart in 2 pieces) so I replaced it ($140 at the dealer). I thought it fixed the issue but I ended up having trouble with them again so I took the truck to a dealer and they replaced 2 more sensors. No more issues after that and its been a month now.

It cost almost $600 to fix.

 

lol for $600 I'll stick to looking out the back window

 

Had the same problem, had to get them all replaced....
