I have being requesting information from Schrader wich are the OEM TPMS sensors supplier for ours OB. This case and procedure is for the Outback 2020-02 / 2024-08,. The programmed sensor for our OB is the 3076 Schrader Snap-In Faraday PAL 433mhz Subaru, is exactly the same that our tires have in, rubber valve model. Is a programmed unit that cost in Europe around 40E but available worldwide. There is other alternatives from Schrader as you can see, as the programmable ones or other version of the 3076 with aluminium or titanium valve. Anyway, the 3076 is plug and play, after installation you shall lock the car for 30 min, then drive normal and the sensor will wake up, recognize the system and the position and start working normal.
Hope this info can help.
