2012 Reverse sensors always go off

Hello,

My 2012 has gotten to the point that the reverse sensors will go off full bore even in a empty parking lot. I do have a ranch hand bumper.

They have never been this bad.

Any ideas?

Make sure they are clean and there is no moisture in them. My 6.4 would have issues for days after I washed it or it rained.

Yeah I have done that a few times. Do I just need to replace them now?

If you have access to a scan tool you can monitor each individual sensor to find the problem one.

Wonder if my HP Tuners will tell me that.

Anything that can get into the body control module or gem should be able to read that data, not sure about a tuner. Or just buy one and keep swapping it until it works. Usually its only one that goes bad..

If you put the truck in reverse with the parking brake on and go back there and put your ear up to each sensor you'll figure out which one is messed up. I can't remember if they click when they're working or when they are broken but it should be easy to isolate.

My 08 did the same thing when one was bad. Just had to replace one and all was good.

Thanks guys

Good knowledge to have! Mine get a little wacky after it rains.

I got 4 new looking sensors off a wrecked VAN for $50 today.

Mine does this too. When the sensors are went should it be expected that they act normally? I just figured the technology sucked.

Yeah it sees the water as an object close to the sensor.

All of them were clicking when it was going crazy the other day. I have not replaced them or messed with them yet. I am in the habit on click them to Off every time I put the truck in reverse.

Mine actually seem to work better when its wet out. Haven't got around to checking them yet but wish when you turned them off they would stay off.

I thought it was absolutely stupid when I bought my truck. Now I find myself only half a$$ed looking back. I don't notice it so much on my truck, but when I get in the bride's ride, I panic. Hers has a reverse camera, but not sensors. I think it's made me a worse driver because I spend on them instead of my eyes, mirrors, and having my head out of my posterior. I'm paying attention to this thread so I know how to fix mine when they inevitably fail.

Mine are getting really bad. I need to work on them soon.
