It depends. Drive it some more and recheck. Sometimes the temp, driving, etc., can affect the pressure. Obviously, if it continues to drop, you’ll want to have it checked.
Easy enough to turn the steering wheel so the tread of the front left tire is visible for inspection. Another possible source of a slow leak is a leaky valve core. Remove the valve stem cap and put some good ol' spit on the valve stem. Any bubbling will indicate a leaky valve core; could just need tightening or it could be due to a small piece of dirt inside the valve core. A bad tire bead seal is another possibility. If you fail to find a puncture or a leaky valve core then try spraying some soapy water on the edge of the wheel where it meets the tire (you can only check the tire bead for leaks on the outside unless you remove the wheel. The faster/easier method would be to take your Model Y to a shop that repairs tires. The shop will have a wheel tank that will quickly find any leaks by showing air bubbles.
Just got the TPMS error message on my MYP last Monday. Nothing wrong w/ the tires and pressure is stable. Had an appointment this morning at the service center and they replaced the right rear sensor. Appointment lasted ~2 hours. This is a frequent issue w/ their latest SW update that somehow causes the TPMS to trip/trigger
Tpms measures tire pressure when you are driving. It measured the 3 ones at 46psi 18hrs ago. They are different than the tire recently measured because they were measured at different times.
Your tires should all be at 42psi cold and it will rise as the tires warm up from driving.

Tpms sensors are in the tire and don't get software updates that I am aware of. All they do is transmit a ping of the tires psi every so often when at speed. There is a tpms signal receiver inside the car. It's a little black box in the back right of a model 3 interior. Maybe that is what they replaced for you.

Per the posts above... you need an updated reading where all 4 sensors got a reading at the same time. So, check it again after the next time you drive it.
Last time I drove it was yesterday evening so this makes sense. Not sure why only one tire was updated though. Hopefully that’s the case and I have nothing to worry about. Thanks everyone!!
Actually, if you do a short enough drive (moving it around the block or something), you can get that. I've watched it update and it does it one wheel at a time (at least on screen), so if you stop after it updates one, but before it updates the next, you basically get that.
