Tire pressure sensors sensitive to pressure wash.

[Odessa]

I pressure washed my 2022 1500 V8 with a 3200 PSI pressure washer and a 40 degree cone. Afterwards, three of the pressure sensors were not registering any reading on the dashboard. I live in Austin, TX and decided to wait and see if the ambient heat would correct the problems. Fortunately, the next day they were all working. Those are supposed to be (epoxy) sealed units, but apparently the pressure was high enough to penetrate. I won't aim the pressure nozzle directly at them again, and am just commenting here so you can avoid doing the same.

I dont know how a pressure washer could screw with the actual tire pressure sensors. They are mounted inside the tire/wheel.

Im guessing something else from the system got wet…but not the actual sensors.
