TPMS light stays on even after resetting it. Good tire pressure. What's wrong?

The *spare tire* is often overlooked when gauging tire pressures .. It also has the pressure sensor and must have the correct psi as well. I’m assuming the tire shop properly synced the new sensors with the TPMS module(?) .. Also the new tire pressures were initialized using the onboard re-set button(?) This may require a *professional scan test* by qualified personnel .. A pro quality scanner combined with a knowledgeable technician are invaluable!
