Question

2000 Nissan Sentra, is it dangerous to drive the car with the p1441 code?

Answer 1

it's not dangerous but it could affect fuel economy

check the fuel cap first, look at the rubber seal and see if there are small cracks on it if so replace with a orginal Nissan one, other than that the list below needs to be checked

-Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking
