My TPMS sensors came on the other day. It was cold and snowing so I figured the tires were low. All 4 were low so I set them at 36 front and 49 rear. Went for a drive, have driven 20+ miles and the light is still on. Is the system monitoring the spare too? If so does anyone know what correct pressure is for the spare?
What else could it be? It should be simple, fill the tires with air and the light goes out...right?
My back-up sensors were messed up with the snow too. But that is another category of problem... No snow on the lens but wails anyway. This happened last winter too. Must be a combination of cold and wet. Parked in the garage, next morning they back up sensor worked correctly
