I have a 2019 RAM 1500 Bighorn 3.6L. A few weeks back one of my tire pressure sensors was indicating that there was an error, as it wouldn't show a reading. I had the TPS on the affected tire (rear passenger side) changed. Not long after that the front drivers side did the same thing, so I had it changed as well.
Fast forward a few weeks later, and now The TPS readings on all four of the tires seem to have an issue. Sometimes the ones I didn't replace show a reading error where they won't show a number, and sometimes the ones I already replaced show the same error. They all seem to go back and forth between showing a failed reading and reading as they should. There doesn't seem to be any rhyme or reason as to when a particular tires sensor shows a failure. Would this be an indication that there's a failure with the entire system, or just four faulty TPSs?
