Tire pressure sensor reset procedure
Tire pressure sensor showing that it is not working for the right rear tire. It is working for the other 3 tires.
These are battery powered and need to be replaced 60 months / 5 yrs, I suggest you have all of them done, another few months and another one will quit working.
