No source ties P1441 to the gas cap.
The brief asked for GM P1441. We found no GM primary source for P1441. GM's 2018 bulletin uses the generic P0496 for flow during non purge. The P1441 we found is on the Honda Passport.
What The Fix Costs
The usual part for this code is the purge valve. Published estimates put it at $210 to $251 at RepairPal. The full table with every source and date is on the cost page. A diagnosis first keeps you from paying for a part you did not need, which is why we price what to do after a failed smog check before the fix.
Getting The Light To Go Off
After the repair the light goes off once the EVAP test runs and passes on three drive cycles in a row, and the code is erased after 40 warm up cycles, per CARB. The test only runs under set conditions such as a fuel level between about 15 and 85 percent, so it can take days.
