I have been trying to track down what I assumed is a leak in my 2019 Limited with the air suspension. Spent hours under the truck with a spray bottle unable to find anything. Ended up setting up AlfaOBD, and gave the system a fresh charge of nitrogen since I had a couple leaks I took care of when I first bought the truck. I'm wondering if these readings are indicative of a bad air ride sensor, leaking air shock, or something else.
