Thanks Kayteg, that’s re- setting or re-learning. Not adjusting the thresholds. Reading the manual is only half the battle.
On edit you may have meant adding air to tires not adding “20psi” to the sensor threshold (which 1 tons don’t have threshold anyway).
Either way, every tpms or tpis system I’ve been around, including a handful of fords too show pressure chenges in real time or nearly real-time and no re learn process is needed under normal operations. Newer vehicles like yours don’t even need re learn when fire position is rotated.
Keller May likely have something wrong with the system that a reset or re learn may fix but probably not the case if it’s already reading the right tires. Worth a shot though, you’re correct.
