What does P0073 Fault Code mean?

[EdMat]

Anybody know what the P0073 fault code is? The only reason I know that it might have occurred is I drove around a bit with the frunk off doing some maintenance. Unhooked the battery for about 15 minutes and after starting it and restarting it a couple times during a short drive it want away. The pictogram it was displaying was the engine symbol on the far right of the display. Maybe it is from the air temp sensor being unhooked with the frunk off? The digital shop manual that I bought online does not list it.

With the frunk off, you did not have the ambient air sendsor conected. With it recconnected, it will run properly.

Jerry's correct. If you don't have all the wires connected that you must disconnect to remove the frunk and you start the engine it will throw that P0073 code. Once you connect all the wires the code will go away. I discovered it when I changed my spark plugs at the 56K service and test started the engine.
