Front Parking Sensor Issue

[centurionkingsley]

I have a 2018 Laramie. I bought it used and one of the front parking sensors was missing. I bought a replacement, but the truck says the front sensors need servicing. Is this something that can be addressed using Alfa OBD?

I had a similar problem. I got the same message and tried to test the sensors in the back, one at a time with a new one, and it would not reset. I then replaced all four and it reset. I then tested the old sensors and found I had two sensors out. When you replace them it takes two to four cycles to reset and work.
Are you still trying to fix it?
