What Non mopar mechanic work are you doing

Im rotating the tires on the Mommyvan. Damn, those tires look 1/2 worn compared the the backs that look new. Tire pressure sensor is flipping out so I need to find out WTF is going on. All the pressure is 40 psi (38 factory and 44 per tire manufacturer) Any way to reset the sensor without pulling the ground for 30 minutes? My OBD2 scan tool is MIA.....
