TPMS Issue/New Tires

[Ricky EMT]

Good Day,

Trying to ask anyone whether professional or novice if anyone has ever had a TPMS issue with their RAM after new tires were installed (same wheels = oem). After new tires were installed on my 2019 RAM Bighorn 1500 (5.7 HEMI New Body w/ RAM Box), I started having TPMS issues. The 1st issue was the front driver side would not register. Returned to tire shop and had the TPMS valve replaced. Every tire showed up as normal. Fast forward a couple of weeks and the TPMS light came back on but would blink and the beginning and then go to solid. Both driver sides would display PSI but not the passenger side. Then the passenger side would show and not the driver. Then the rear passenger tire would show and not the other three. Then so on and so forth with all types of possibilities that I thought were not possible. By the looks of things, all sensors work per say. I'm tending to lean more towards that the actual TPMS module that receives the signal from the sensors is bad. Any suggestions or insight into this weirdness. Any help is greatly appreciated.

A 2019 probably needs a replacement of all the sensors. You can do just the bad ones (they can test each) but should just do the full set. They are nearing the end of their life. Sensors should be tested and recalibrelated after changing tires, some vehicles can relearn them but, again, yours are most likely in need of replacement.

I agree sounds like Battery on TMPS going bad
They last 5 to 7 years average !
Mine lasted about 9 years !

Not sure if this will help but
Were new, genuine, Mopar TPMS sensors installed? If not try that first... I've seen issues with some knockoff parts/modules causing strange issues (on the 4th gens).

** I've also had an aftermarket front camera I added to my prior 2013 truck pick-up noise/EMF (from radiator fan?) and mess with the tpms signal on the front tires.... Had to remove it and try and different brand camera)

(Early 4th gens had 2 different't tpms sensor frequencies depending on the the year. not sure about the 5th gens).
