Front Park Sense throws an error at 6-8 mph

[John R]

This started out as an intermittent issue. I'm getting a message and a ding every time I accelerate through 6-8 mph. The message advises that I should service the front park sensors. The system then disables the front sensors (light in the button comes on). When parked, the sensors work as they should and indicate an object when someone moves something near it.
I changed all 6 sensors----no change. I took it to my dealer. They said it was the module behind the driver side kick panel. I ordered one ($85) and replaced it. No change. It still fails and the dealer mechanic doesn't know what should be done next. I hope some of you guys have ideas.

I am having a similar issue with my rear ones. I believe mine is a failed sensor, going to let the dealer look at it under my Lifetime Maxxcare warranty.

In your case, if you have changed all sensors and the module, did you check to make sure the truck knows it has new sensors and a module? I don't know if these have specific IDs tied to them as some other components do. There is a possibility one of the sensors is still bad. You also may have a wiring issue, such as a broken wire.

In hindsight, I would not purchase the park sensors ever again on any vehicle.

I am having the same problem on my 2018 RAM 1500. Replaced front sensor #4 as the scan told me to but no change.

Over a year ago I posted that I had this problem and replacing the sensors didn't fix it. Well, I learned that the sensors Amazon sold me weren't for a 2018. I put the original ones back in. A week ago I took it to the dealer for something else and asked if they could look for a code related to the park sensors. They said yes and it pointed to one of the front sensors. I ordered some again from Amazon and the one that was called out fixed it.

I suppose I should update my issue as well - TWO of my rear park sensors were cracked and any time they got water in them they would create an issue and short out. Water evaporated out and they would function normally again, until water got inside again. Both replaced under Lifetime Maxxcare. Apparently they're considered a 'safety' item.
