Fault Code PO1633 means KAM voltage too low. KAM means "Keep Alive Memory". When you disconnect the battery or if the battery is failing, this code can occur and the computer will "forget" some of it's operating parameters. I expect the computer can relearn these when operating normally for a while so I would ignore the code if the battery is able to start the car. Do a voltage test with the motor running 14.5 volts, and again when it's off 12.0 volts. If that test is okay, I would not worry.
