Investigating P0441 on Your 2022 Subaru Forester
A P0441 code on your 2022 Subaru Forester signals incorrect purge flow in the EVAP system. The Forester uses a 2.5L boxer four-cylinder engine with symmetrical AWD. P0441 targets the purge circuit — the purge control solenoid and vacuum lines routing fuel vapors to the engine.
How the Code Sets
The ECM opens the purge control solenoid during driving and monitors fuel tank pressure. When flow deviates from calibration, P0441 stores.
Ranked Causes
- Purge Control Solenoid Failure (35% likelihood) — The primary suspect. Part: $30–$75. Labor: $55–$115.
- Vacuum Line Issue (20% likelihood) — Cracked or loose hoses. The 2.5L boxer is naturally aspirated with moderate heat output. Repair: $12–$40. Labor: $30–$80.
- Vent Control Solenoid (15% likelihood) — Affects pressure dynamics during purge monitoring. Part: $30–$80. Labor: $75–$160.
- Fuel Tank Pressure Sensor (10% likelihood) — Inaccurate readings. Part: $30–$80. Labor: $50–$105.
- Charcoal Canister (10% likelihood) — From overfilling. Part: $95–$260. Labor: $75–$160.
- Gas Cap Seal (5% likelihood) — Check seal. Replace: $8–$15.
- Wiring/Connector (5% likelihood) — Corroded connector.
