Faulty Back up Sensor?

[diggerznwt]

I just dove head first into the world of Ford Super Duty. I've always been a GM guy, but last week I traded in my 06 GMC 3500 Dually for a 2012 F350 Lariat dually. I love the truck and am actually pretty impressed with the fuel mileage and the fit/finish. My GM definitely rode nicer though, but they've always been known for being smooth riding.

The only problem I am having is that the back up alarm goes off every time I put it in reverse, like there is something behind the truck. I have cleaned the sensors, many times, so it's not something on the sensors. I'm wondering if there are others out there that may have come across faulty sensors or wiring? I may end up taking it in to the dealer to have it looked at. I know you can turn the alarm off, but it doesn't stay off. Every time you turn the truck off and restart it, it resets back to "on". Not a big issue, but an annoying one coming from an $80,000 (cdn) truck. Thanks in advance.

They could be faulty, or it could be a short. Mine actually shuts off and the light on the button comes on showing its off when I put it into reverse. I am pretty sure its a fail safe and its a short somewhere.

My alarm will go off if i have the tailgate down, or when dirt or ice was covering up a sensor..
If this isnt the case for you guys maybe take to dealer

I'm pretty sure that just turning it off on the screen that pops up while you are in reverse is the temporary "off" you speak of. If you go into settings, I believe you can disable the reverse sensor always? I'll have to double check that, but I thought that was the case...

The GM's ride better because they use the same suspension components that they put on the Impala's and Malibu's.

Mine are the same. 90% of the time they beep even if on level pavement. I'm guessing that one of them is acting up but I haven't had the chance to leave it with the dealer yet.

You dont have a hitch in the receiver do you? My back up sensors pickup my bumper pull travel trailor hitch while in the receiver.
