TPMS sensors question
I bought older lexus wheels from someone who used them on his IS350, I have a IS250 F sport. I didn’t get the TPMS senors installed but my car is still giving me my PSI readings for each wheel. Would it be possible that the wheels already had them installed and my car connected to them or is that impossible. I can see the pressure going up and down depending on the temperature outside.

Unfortunately that would be impossible. For the vehicle to read the sensors the code for each sensor would need to be programmed into the vehicle.
If the vehicle is parked near the wheels you took off, it's possible they could still read the pressures, but it's highly unlikely.
Drive the vehicle for more than 20 minutes consecutively and see what the readings are then.

Some places will program the wheels without charging you. I know NTB did that for my car. If the sensors weren't registered, you'd see "---" instead of a numerical value. The Lexus dealers like to charge to reprogram but maybe Costco was more customer friendly like the NTB.

If you bring new wheels they would transfer them over and still replace the seals etc and it should be included in their price. Usually places ask if your car has TPMS because they will add on the price for TPMS service.

Sensor is attached to the wheel, not the tire. All they usually do is replace the seals on them to make sure no leaks occur.
