New wheels with TPMS, but not registering / throwing error
After installing my new HRE wheels, which came with TPMS installed, I have not been able to get a reading on the pressure (and eventually this turns into a malfunction which says service required). This is what I've done/tried so far:
* Without changing anything, I went out for a short drive consisting of start/stop 35 mph city driving followed by ~5 miles freeway speed, parked, then returned home - no error, but it was just stuck on "reading" the entire time.
* Still without changing anything, I went out for a longer drive of non-stop freeway speed, and closing in on 8-10 miles I got an actual TPMS malfunction.
* After doing some searching, it seemed like the trick was to toggle the wheel setup in the PCM menu, which forces the car to forget the old sensors entirely - this displayed a different message indicating it needed to relearn entirely, but again it was stuck on reading during the entirety of mixed city/freeway driving, and just so happened to switch to malfunction as soon as I returned home and parked.
Is there anything else I should try? Do I just need to keep trying / give it more time? The tires came a bit overinflated at 46-48 psi, so I lowered them to 38 front, 40 rear, which is still a couple pounds over where I had the stocks, but it seems like that should be fine (and the door jam actually recommends higher...but when I had it at 36/38 the PCM reported 0 psi deviation...)

I know it's an old thread, but I assume you checked this
https://rennlist.com/forums/991/831416-tpms-reset.html
and specifically reply #4? I don't know what model you have but I assume they're all the same

I’m taking a break from troubleshooting tonight and will try again tomorrow

If that doesn't work, if you have an analyzer like PIWIS or Launch, maybe you can try to get them to register that way (unlikely, but you never know, check the battery status on the TPMS'). If that doesn't work, then a re-flash may be needed. Is the car still under warranty (you don't say what year/model....).

Weird, when I changed winter to summer tires several months ago, simply toggling the menu did the trick (wasn't aware of the 20' separation between old and new sensors as in my case they sure weren't). But I do recall that for some you do need to drive them a bit. Definitely worth a try.

Not sure how to check the TPMS battery...if I can’t get this resolved by the time I get my springs on, I’ll see if they can check it out for me then.

Yea I’ve gone on multiple 10+ mile drives and it’s the same thing: starts off as reading/monitoring, and then switches to fault.

If you have an analyzer that handles TPMS' you should be able to check whether they're sending out signals. If not any competent tire shop has such a tool. You said you just put new rims with sensors on, who knows how long they've been on a shelf. Also make sure whoever sold them that they are 433Mhz.
