If you had very high wind situation, it may have tripped a rollout switch in the burner compartment of the furnace. You can check this. First power off the furnace. remove top panel where burners are. near the top of the burner tubes are rollout switches, there may be two of them, if either one of them trip, it will give you the same error. Each switch is small in diameter, has usually two wires connected to it, however, one side of one of them, may have two on the same terminal making a total of 3 wires. in the center of the switch may be a reset, depress this switch. on both if two or more. power up the furnace and see if you get the same code.
