Engine fault codes on 1996 Saturn SL2

I have the following engine fault codes come up when the computer is plugged in:
P0155, P0141, P0562, P0563, P0560, P0565 and P0605. Are all of these due to the need for another Alternator/voltage regulator?

Asked by for the 1996 Saturn SL2
These codes could all be related to low system voltage. Is you battery light On? Have you had your charging system checked out? It sounds like your car needs a good shop to do a charging system inspection ASAP!. Good Luck!
