P3190 code with FF data (weak engine)

My wife's 2005 Prius started revving rather high about 6 months ago. Then yesterday while parked for a while with the engine running, it generated a check engine light. The diagnostic computer kicked out code P3190 which is generated when there is weak power at the engine. From what I have read it can be generated by many things, such as air intake, fuel pump, etc. Does anyone know how to read the following data and be able to identify anything that would indicate the problem? Thank you in advance.

I hope someone on here can help with that......but the odds aren't too great as I don't think we have many (any?) really expert mechanics present.

If you haven't already, please test the 12 V battery and consider changing it out if it's over 5 years old, or tests bad of course.
