TPMS reading incorrect pressure??

[LRojas]

I have a 2019 Laramie RWD, as far as I know, the Bridgestone Dueler Alanza's are stock as well as the TMPSs. I noticed that the sensors were reading 38 psi, except for the one that had a bolt in it. I plugged the hole and aired up the tire using a manual pressure gauge to 38psi. I started the truck and noted that the tire on the TPMS showed 44psi. I checked the other tires manually and they were reading 30-31psi. I aired them all up to 38psi and now all the tires with the TPMS read 43-44psi.
Is there a way to "calibrate" the TPMS to read what the manual gauge reads?

I don’t know the answer (I presume it’s possible)…but do you have a calibrated manual gauge?

Did you take the vehicle for a ride and recheck? The sensors need to be woken up in order to send an updated pressure reading.

I figure they were awake since they went from 37-38psi to 43-44psi, but I did go for a 10 minute ride anyway

Interesting...I really do not think there is a calibration for these as the TPMS sensors are calibrated at the factory where they are produced. You should make an appointment at the dealer and get this checked out. Maybe a bad module that monitors the sensors.
