P0441 on a Subaru: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can keep driving — this is an emissions fault — but fix the purge system soon to avoid fuel smells.

What P0441 means on a Subaru

On a Subaru, P0441 means the EVAP system is not purging fuel vapors at the flow rate the engine computer expects. The purge control solenoid that opens the vapor line to the intake is the usual cause, either sticking or getting slow with age. The car drives normally, so the check engine light is the main symptom.

Is P0441 common on Subarus?

P0441 shows up on Subarus like the Outback, Forester, and Impreza as the purge control solenoid and its rubber hoses age. Subaru's EVAP system runs a purge check during normal driving, and any small change in flow can trip the code. The solenoid itself is the top suspect, with cracked hoses second.

Commonly reported on: Outback, Forester, Impreza, Crosstrek.
