Troubleshooting A PressurePro TPMS Sensor That Isn't Reading Pressure

Question:

I have a 2021 Tiffin Phaeton diesel pusher motorhome. It has the factory setup of all six tires with Pressure Pro tpms. One outside dual monitor does not work Ill get 4 lbs at times, then just dashes at the control panels. I have changed out the monitor with another, and get the same result. That tells me there is an issue at the valve stem, not the monitor. Should I change out the valve stem? Or is there something more I can do? thank you for your advice.

Since you swapped out the PressurePro FX 4 TPMS for RVs and Trailers # 372FX4K sensor with another and still got an error with just that one wheel you most likely just have a bad valve core and it's not allowing air to pass through to the sensor for it to properly read the pressure. I recommend first replacing the valve core and if that doesn't solve the issue then fully replace the valve stem.
