P0441 on a Mazda: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can drive it, but have the purge system checked soon if you notice fuel smells or a rough idle.

What P0441 means on a Mazda

On a Mazda, P0441 means the EVAP system is not purging fuel vapors at the flow rate the engine computer expects. The canister purge valve that routes vapors into the intake is the usual cause — it may be sticking or slow to open. The engine keeps running normally, so the check engine light is the main sign.

Is P0441 common on Mazdas?

P0441 appears on Mazdas like the Mazda3, Mazda6, and CX-5 as the purge valve ages and its rubber hoses get brittle. The computer measures vapor flow during a purge test, and a sticky valve or small hose leak throws that reading off. It is an emissions fault, not a mechanical failure.

Commonly reported on: Mazda3, Mazda6, CX-5, CX-9.
