the low tire warning shows on dash and all tires are equal on air at 38 psi. when the engine is started no tire information is displayed. The spare is also up to pressure.

If you have ensured that all of your tires are properly inflated then you may need to have the system reset at the dealership.

if you have your owners manual it will tell you on how to try to reset manually otherwise you'll need it scanned for codes by a mechanic to see if the sensors are bad or something else.
