2015 RAM Laramie I bought new so no known issues.

I'm having a problem with the front parking assist sensors. One day I start my truck and get the message that the sensors do not work. I press the enable/disable button on the console but the error will not clear. I have tried a few things but no luck.
Removed all sensors, clean them, none of them seem damaged.
I tried to rule out which one was damaged (measured resistance with a multimeter but all measure about the same).
Does anyone know how to tell if a sensor is bad/is there something else I need to check?
Any help would be appreciated it.

Thank you.
