Aftermarket TPMS Sync/Position programming

So I got new wheels and new aftermarket TPMS sensors from ebay, 3 of the sensor work, but one is not, the car keeps resetting trying to activate or sync the 4th sensor.......... Either way, I was trying to wake up the sensor by lowering the PSI on the tire to 20psi and raising back to 42psi, I raised both back tires to over 42psi just for testing and when the car synced the 3 good sensor it showed the higher psi on the front tires instead of the rear . I know some cars you need to program the position of the sensor (front/back/driver/passenger) you start on the front passenger side etc and the car will honk at you when you lower the psi confirming thats the correct tire/sensor on that side etc. .......... the model 3 only has Reset to Factory or Learn TPMS, I pressed both , drove over 50-100 miles, the 3 good sensors sync but not in the correct position. Anyway to fix the problem?

The sensor I got are the correct part# clones I'm guessing, Im getting a replacement for the one damaged.

Here is my biggest problem, sensors locations are all wrong, Im hopping once I get the new sensor installed it will do some sort of signal triangulation to know the correct position of each sensor. right now one match.

What a mess!

Did you say right now only one matches the position as displayed?

Because your picture shows all 4 of them are displayed in wrong positions and none of the is displayed in any correct position!

Did this ever get fixed by chance? I’m having similar issues. Also does anyone know if these ones off eBay that are OEM do they need to be woken up so to speak/ programmed first?
