Understanding P0441 on Your 2024 Subaru Forester
A P0441 code on your 2024 Subaru Forester indicates incorrect purge flow in the EVAP system. The all-new 6th-generation Forester uses a 2.5L boxer four-cylinder engine on the updated Subaru Global Platform. P0441 targets the purge circuit — the purge control solenoid and vacuum lines routing fuel vapors to the engine.
What P0441 Means
The ECM commands the purge control solenoid open during driving and monitors fuel tank pressure. When flow doesn't match calibration, P0441 sets. On a first-year redesign, this commonly indicates a factory issue or software calibration.
Primary Suspects
- Purge Control Solenoid Defect (30% likelihood) — Factory-defective purge valve. Warranty replacement.
- ECM Software Calibration (25% likelihood) — First-model-year refinement for the new platform. Warranty reflash via SSM.
- Vacuum Line Assembly (20% likelihood) — Production assembly issue with new routing. Warranty repair.
- Vent Control Solenoid (10% likelihood) — Factory defect. Warranty replacement.
- Fuel Tank Pressure Sensor (10% likelihood) — Out-of-spec. Warranty replacement.
- Charcoal Canister (5% likelihood) — Only from overfilling. Warranty replacement.
New Platform
The 2024 Forester is a complete redesign on an updated Subaru Global Platform. First-model-year TSBs for EVAP calibration are common. Your dealer's SSM system checks for applicable updates automatically.
