Outdoor thermometer only reads when someone sits in the passenger seat

Everyone I tell this too says I’m crazy. I believe it is the car, not me, as a few other people came up with this idea. Does anyone have any ideas about this?

Completely off the wall guess, I wonder if a wire is pinched somewhere, but when someone sits in the passenger seat it changes the load balance just enough to unpinch the wire…

Our Acura only flashed a TPMS error when someone sat in the back seat. Dealer never did find the problem and just traded.
