OK, so I took my car in to swap out he rear tires and in the process, the shop broke one of the TPMS. Since it was on a Sunday, they couldn't get a replacement right away so the tires weres swapped and since one TPMS was broken, I told them to just leave the other one out also. So now I'm driving with only the two front sensors on.

My question is: Why hasn't my TPMS sensor light come on?

 

What shop was it in SoCal?
