My 2004 F-350 6.0 power stroke suddenly lost all electronics and then eventually stalled. It has happened twice. Gauges go out everything and when I dry to put it in Drive it dies. Eventually it will run. I used a home scanner and 2 different apps that both can read it. One gave this code PAO11 the other had a ton of glow plug injector codes from previous issues. I cleared the errors and nothing came back with that particular app however the other still says the mentioned error. I really can't afford to pay a garage to search for hours. Would there be a sure fire part that I could replace that would likely solve this or do I need to bite the bullet and have them check every step mentioned? :(
-
Not sure if this is worth mentioning, but I just replaced water pump and was running Sea Foam in the tank and crank to clean it out. Could it be possible that I merely need to clean the system more to flush anything that may affect sensors? Dumb question I know, but this is not the nest timing financially. lol Only had the truck 3 weeks. :(

I couldn't find any information about the P0A11 on the factory service manual. Do you happen to have the other codes? Unfortunately there are many things that could give you the symptoms you describe, try solving the other codes and not the P0A11 code.
