po 410 is for the air system (air pump)
po 1441 is for the evap system (fuel vapor recovery)

you need specialized equipment to accurately diagnose both things

nothing i can do myself? replace the part?

you can replace the air pump but its would just be a guess. most of the time thats what i find wrong for that code. a reman air pump goes for about 140.00

the evap take a look at the purge valve and attaching hoses

EVAP canister purge valve leaking internally.
EVAP purge and engine vacuum lines switched at the EVAP canister purge valve.
EVAP canister purge valve control circuit grounded.

could also be a bad gas cap
