Answer
P048 Current = EGR malfunction. This one you need to be concerned about.

P020 History = Shorted fuel pump. Nothing to worry about.

P039 = Trans mission 4th gear fault. Nothing to worry about.

P052 history = somebody disconnected the PCM computer or removed the battery cable.

I ca e-mail you some diagnostic pages on the P048 code.
