If the TPMS sensors were replaced (not refurbed with new batteries), they need to be synced with the vehicle. There's a special tool for this. In order for the vehicle to know which sensors belong to it and which position on the vehicle the sensor is at, the vehicle has to be given "introduced" to the new sensor. If not, it won't have a clue and you won't get any readings, which it seems you are experiencing now. You may have to go to a different mechanic or tire shop to get them registered, as it seems the one which changed them out doesn't have a clue.
