P0441 on a Nissan: Causes, Fixes & Repair Cost

🟢 Low severity · drivable

You can keep driving — this is an emissions-system fault, not a mechanical one — but get it fixed before your next emissions test.

What P0441 means on a Nissan

On a Nissan, P0441 means the evaporative emission (EVAP) system is purging fuel vapors at the wrong flow rate. The purge valve opens to send stored fuel vapors into the engine, and when the computer sees the flow is off it sets this code. The car usually keeps driving normally.

Is P0441 common on Nissans?

P0441 shows up on Nissans like the Altima, Rogue, and Sentra, often as the purge valve ages and sticks. A loose gas cap and cracked EVAP hoses are also common triggers. This is an emissions fault, so you may notice nothing besides the check engine light.

Commonly reported on: Altima, Rogue, Sentra, Pathfinder.
