Park sensor failing on the front. How do I test? 2018 2500 SLT Diesel

[John R]

Every week or so I get a "ding" and a message saying that the front park sensor(s) are failing and the computer turns them off. I've wiggled the connectors on each of the 6 sensors and attempted to test each one but so far my tests are inconclusive. After the next engine start they seem to be working again. Help!

If you can get the codes retrieved to find out which sensor is having the issue it’s a lot easier.

Basically you find out which sensor sets the dtc, then swap it with another sensor and see if the dtc changes or not.

You’ll need a scan tool that can retrieve body/communication codes though.
