TPMS Cause Of Leaking Air?

[tom8]

My rear wheel has been causing my tpms light to come on. I don't see a crack in the wheel, and I don't hear a hissing sound meaning an air leak. Can the sensor be faulty or the cause?

It is possible that it may be leaking from a bad valve stem. Did you check for a nail in the tire? Nonetheless, I would take it to a tire shop.
