ERROR CODES PROBLEM

Chrysler PT Cruiser

I have a 2002 PT Crusier with 169000 miles on it and in the last month Ive had codes 603, and now 505. The mechanic replaced plugs, and wires. Other than this, the car has been wonderful, I still have the original battery, headlights, etc. Everything else is working fine.
Any help?

P0505 Idle Air Control System
P0603 Internal Control Module Keep Alive Memory (KAM) Error.
So what is the problem now?
