On my last road trip, I lost one of my tpms sensors along the way. My tire pressure light came on and it started reading double dashes (--). I first took it to a local tire center that I've used before. They put on after market sensors but after a few days, they only got 1 to relearn to the truck, the other 3 had double dashes. They refunded my money and I took it to Discount Tire. They also replaced the tpms sensors with an aftermarket set and like the previous place, could only get 1 sensor to work. Ironically, it was the same one that worked after the first shop replaced them. I got another refund and took that money and put it towards buying an OEM set of sensors from Mopar. I took it back to Discount where they put them on for me for free. However, it's been several days now and I still only have 1 working sensor, the same one that has worked after all 3 sets have been installed: the front drivers side one. Has anyone ever had this type of issue or even heard of it? I don't think the RFH, radio frequency hub, is bad but I'm not sure about that either. If anyone has any thoughts, I'd appreciate hearing them. Thanks!

 

I'll be monitoring this thread as I'm having a nearly opposite but similar issue in my 2018 Charger. My driver's front (LF) TPMS refuses to show up on my information center, but when I scan the sensor with my TPMS programmer it finds the sensor no problem and says the battery is "OK," just like the other 3 sensors. I checked the RFH and it has the correct sensor ID for that wheel. I programmed the RFH to think that the LF sensor is on the RF of the car, and vice versa, but the RFH then thinks the missing sensor is the RF. That leads me to think that the sensor is the issue rather than something with the car. From what I can tell from the service manual, there is only one TPMS antenna, not a separate antenna at each corner.

I need new rear tires (strangely, they're nearly bald even though there's still a lot of tread left on the front tires....) so I figured I'd just get all new sensors at that time, but your experience has me wondering if I'll likely encounter a similar issue. If so, I'll be certain to reply here, and hopefully also have a solution. Until then, good luck and I hope you get the issue resolved!
