The valve model number helps.
The gas valve didn't know the pilot lit (problem with flame sensor or flamesensor circuit) so the smart valve locked out. This lock out is the code flashing. It's possible there is a problem with the valve also, although I don't think so. The valve wouldn't have opened when you connected your meter to it. Manufacturers are pretty particular about NOT allowing the gas valve to open until ALL the safety devices are proved. There is no simple way to trick a flame sensor since it generates current.
There is a flow chart in the gas valve manual that describes the Order of Operations.
1st, Disconnect the flame sensor wire from the valve, place your micro amp meter in series with the valve and sensor. Let the heater cycle. You should read between 0.5 (yes point 5) and 10 micro amps withthe pilot lit. I don't really know what it should be. Honeywell may have it in the instructions.
If you have less than 0.5, the main valve will not open. I would be suspicious of a ground or dirt issue at anything less than 4 or 5 (5, not point 5) micro ohms.
If less than 0.5, Clean flame sensor with the back of a knife and check grounds. Re check amps.
If amps are more than 0.5 and the main valve won't open, Valve is likely toast. (Your electrical schematic should verify this)
I would not start changing parts until I was pretty confident in what was wrong.

Today's Featured Article - Product Review: Black Tire Paint - by Staff. I have been fortunate in that two of my tractors have had rear tires that were in great shape when I bought the tractor. My model "H" even had the old style fronts with plenty of tread. My "L" fronts were mismatched Sears Guardsman snow tires, which I promptly tossed. Well, although these tires were in good shape as far as tread was concerned, they looked real sad. All were flat, but new tubes fixed that. In addition to years and years of scuffing and fading, they had paint splattered on
