TSS sensor issue, why?

Well I guess I was premature in my last post about my grille change out. After upgrading my 2019 TRD sport grille to the pro grille and adding the garnish to cover the TSS sensor I noticed that dreadful idiot like would come on after driving and would reset when I shut the eng off. But it keeps coming back on. I thought the computer would re boot but not sure why it has not. Any ideas?

 

Is the new grille OEM or a flea-bay knockoff?

 

Yeah it’s after market.

 

Update on that pesky tss sensor,
I kept getting the “turned off” idiot light after changing out the grille. Finally just said screw it, disconnected the battery cables, rubbed them together a few times and re connected them. Problem solved. Drove over 100 miles afterward and no error. I’m happy.
