Yes, which is why indirect TPMS (using ABS wheel speed sensors to detect loss of pressure via circumference) is a bit more convenient and a lot cheaper.
Or you can live without TPMS. | this. no need to replace tpms sensors, change service packs, deal with leaking o rings and seized nuts etc. mostly only the german manufacturers run indirect systems. though i think the toyota sienna in the mid 2000's also did before switching to actual sensors.

Just put on and go, no reprogramming necessary?
Is it just certain cars/manufacturers that allow 1 set vs 2 sets of tpms IDs? |
honda/acura will often relearn themselves. its all dependent on the vehicle and brand. some toyota actually have a button in the glove compartment that can hold two sets of tpms sensors in memory, but often shops perform relearn procedures while in the 2nd tpms mode and re-write the sensors twice. can be very difficult to figure out why the dash light is on etc etc. Quote:

Some cars auto detect new tpms, some need programming, some can handle multiple sets etc. etc. depends on make/model | yeah its a big hassle. especially when people buy winter steel wheels that dont have sensors in them, but they keep the summer wheels in the garage and park next to them every day. the tpms light comes on after driving for a while. but the next day its off again blah blah. really hard to explain to people whats happening. they complain and complain but are unwilling to spend the $200 on a second set of sensors to solve the problem |
