Understanding P0441 on Your 2024 Hyundai Sonata
A P0441 code on your 2024 Hyundai Sonata indicates incorrect purge flow in the EVAP system. The Sonata offers a 2.5L four-cylinder (standard), 1.6L turbo hybrid, or 2.5L turbo (N Line). P0441 targets the purge circuit — the PCSV (Purge Control Solenoid Valve) and vacuum lines routing fuel vapors to the engine.
What P0441 Means
The ECM commands the PCSV open during driving and monitors the fuel tank pressure sensor. When flow doesn't match calibration, P0441 sets. On a current-model-year Sonata, this is fully covered under warranty.
Primary Suspects
- PCSV Defect (35% likelihood) — Factory-defective purge valve. Warranty replacement.
- ECM Software Calibration (20% likelihood) — Purge flow monitoring refinement. Warranty reflash via GDS.
- Vacuum Line Assembly (20% likelihood) — Production assembly issue. Warranty repair.
- Canister Close Valve (CCV) (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.
Hybrid Note
If your Sonata is the hybrid, the gas engine runs intermittently. EVAP monitors activate only when the engine runs, so code detection and clearing takes more drive cycles.
Industry-Leading Warranty
Your 2024 Sonata is covered by Hyundai's 5-year/60,000-mile basic warranty and 10-year/100,000-mile powertrain warranty (original owner). All EVAP components are covered. All repairs are free at any Hyundai dealer.
Service Visit
The technician uses GDS to check for TSBs, command the PCSV, monitor pressure data, and run EVAP diagnostics. Most P0441 repairs take 1–2 hours.
