TPMS Question

After a rather unforseen tragedy of my caliper bracket falling and murdering my tpms sensor. I got it replaced and dealer says they have no idea why the light won't turn off. Could it be b/c I haven't put the spare back into its cubby or nah? Honestly ain't super worried about it, since if anything a piece of tape will solve the annoying light

 

See what the pressure is on that tire. It may be too low.

 

The one that tpms died on was 40 somethingish, compared to the 55-56 of the other 3.
I filled them all to the summer 60

 

could be a defective receiver its located in the rear underneath the headliner close to the third brake light

 

Don’t won’t to assume wrongly but when you say dealer, does that mean they registered the new sensor ?
If they did, they can see everything they need to see with Techstream and know if things are ok with the TPMS, even the trouble code showing which TPMS sensor ID is the culprit.
