I would pull the connector from the ECM and check for any signs of water intrusion/corrosion. If it keeps acting 'strangely' and throwing random codes like that, I would look into that connection first. the ECM is in a pretty crummy location, especially if your cowl panel to hood seal is damaged or not sealing (water can run right down the firewall to the connector).
