31 is the airflow meter signal. It means you are not getting the Hz signal in its voltage range. 34 means the airflow meter is showing way to high of a frequency signal. Clear them and recheck.

Also if that doesn't work ( clearing them ) then check the connector. I had that issue with mine a few times and it turned out that the connector was not snapped in all the way.

Pull the EFI fuse for 30 seconds. By showing the description, I was hoping you see the contradiction in 31 and 34.
