P0441 on Subaru vehicles
EVAP Incorrect Purge Flow — what it means on a Subaru, whether it's safe to drive, and the fixes by model and year.
P0441 on a Subaru means evap incorrect purge flow. Most vehicles stay drivable short-term, but diagnose it promptly. The most common cause is failed evap purge valve (purge solenoid) stuck open or closed (typically $80–$300). Pick your Subaru model below for its known failure patterns, recalls, and TSBs.
What does P0441 mean on a Subaru?
P0441 is set when the EVAP purge monitor does not see the flow of fuel vapor it expects between the charcoal canister and the intake manifold. The ECM commands the purge valve open and watches fuel tank pressure — and on many vehicles short-term fuel trim — for the corresponding response. Too little flow, no flow at all, or flow when the valve is commanded closed will all set P0441. This is a purge-path code, not a leak code: it points at the purge valve, its vacuum hose, and the canister, rather than at a hole in the sealed system.
P0441 is a standardized OBD-II code, so its definition is the same on every Subaru. What differs by model and engine is which cause is most likely — pick your Subaru model below for a diagnosis tuned to its known failure patterns, recalls, and TSBs.
Is it safe to drive a Subaru with P0441?
In most cases a Subaru stays drivable for short trips with P0441 active, but diagnose and repair it promptly. This is a low-severity code — ignoring it can lead to further damage or a failed emissions test. Exact tolerance depends on the model and engine.
What causes P0441 on a Subaru?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|
| Failed EVAP purge valve (purge solenoid) stuck open or closed — Stuck closed means no purge flow at all; stuck open adds rough idle and hard starts to the code. | Most common | $80–$300 |
| Cracked, kinked, or disconnected purge hose between the valve and the intake | Common | $30–$200 |
| Blocked or fuel-saturated charcoal canister restricting vapor flow | Common | $200–$600 |
| Failed EVAP vent valve preventing the canister from drawing fresh air during purge | Common | $80–$350 |
| Failed fuel tank pressure sensor reporting the wrong response to purge | Occasional | $100–$350 |
| Damaged wiring or connector at the purge valve | Occasional | $50–$250 |
| Failed PCM driver for the purge solenoid | Rare | $400–$1,500 |
Repair costs are typical US ranges and vary by Subaru model, model year, and labor rate. A diagnostic trouble code is a symptom, not a guaranteed failed part — confirm the root cause before replacing anything.

What are the symptoms of P0441 on a Subaru?
Check Engine Light is illuminated. No drivability problem in most cases. Rough idle or stalling if the purge valve is stuck open. Hard start immediately after refueling (stuck-open purge valve). Faint fuel smell around the engine bay. EVAP readiness monitor will not complete. Vehicle will fail emissions / smog testing
