Sparatic Reverse Sensors
 

When I first start my truck and put it into reverse my reverse sensors will work for 5-10 seconds then stops completely. Then they won't work at all, until I turn off the truck and start up again then it does the same thing again. What could this be? Anyone have this issue?

Can't say that i had this issue...usually the only time i have problems is when it snows or I get mud on the sensors. So i would make sure they are clean and one of the sensors doesn't have a crack in the lens.

Mine are the same way. I wish they would just fail and be done with it. I'm guessing, as I haven't wasted the time to figure out exactly what's happening. But you probably have a intermittent connection someplace in the wiring harness. I say this because I read about someone who spent a fair amount of time searching for the problem in his system. It ended up being a connector that is located some where near the transmission.

I figure it's just not worth the time to try to solve this problem as I don't use reverse enough for it to drive me nuts.

The sensors are clean and free of mud. There are no cracks. I had Ford stealership take a look when I had an oil change and they never mentioned anything about loose connections. They said I need to replace part of the sensor system. I don't have the part # in front of me but they gave me a $250 to fix.:mad: The part was only $35- $50 the rest in labor.

yea bud same boat as you once i put it in reverse it makes a cherp and then doesn't work they told me the same thing but it was about 300-400 i think with labor but i don't use it to much so i figured that i would just leave it be till someone rear ends me then put that in on the insurance claim lol....

My 04 FX4 did something like this. It would act real crazy in the summer months when the temps were in the 90's. I have an 05 Lariat now and have not had any issues with these sensors. Good luck.
