try: www.obd-codes.com

Everything you want to know is on that site. You will find all your codes except the P01700, and I think that one is
"manufacture specific", because I can't find it on that site. But, there are so many sites if you GOOGLE search OBDII codes, I'm sure you can find something.

So, the P0170 is a fuel trim (bank 1) problem
The P0441 is the Evap. Emission System and incorrect purge flow (be sure gas cap is sealed!)
The 505 is the idle air speed control system

Hope this helps. You will find that for each of these, there are several possibilities as to the fix.
