Default My TPMS journey

Hey guys!
2011 Ls 460 RWD. My tmps one day, 1 month ago was have trouble locating the 3rd tire pressure by showing dotted lines. Within a day, the Tmps light came on and would not allow to see any of the pressures. light stayed on for 2 weeks. Then, one day with the light on, parked on an icline for 4 hrs. got in the car, drove away and no light. been off for 2 weeks. no temp change. pressure was checked every day 36 cold. 35 spare. even ordered new tmps. what does everyone think it was? only thing i did was wash car and then add air to make tires 36 from 33 cold!

Most likely a "going bad" TPMS sensor...... Replace it.

It is difficult to give you advice without knowing what your car's TPMS warning thresholds are set to. Your car has 5 independently-settable low-pressure warning thresholds (one for each wheel, including the spare).
