Understanding P0441 on Your 2024 Hyundai Tucson
A P0441 code on your 2024 Hyundai Tucson indicates incorrect purge flow in the EVAP system. The Tucson offers a 2.5L four-cylinder (standard), 1.6L turbo hybrid, or 1.6L turbo PHEV. P0441 applies to all gasoline-powered variants and 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 Tucson, this is fully covered under Hyundai's warranty.
Primary Suspects
- PCSV Defect (35% likelihood) — A factory-defective Purge Control Solenoid Valve. Warranty replacement.
- ECM Software Calibration (20% likelihood) — Purge flow monitoring refinement. Warranty reflash via GDS.
- Vacuum Line Assembly (20% likelihood) — A hose not fully connected during production. Warranty repair.
- Canister Close Valve (CCV) (10% likelihood) — Factory defect. Warranty replacement.
- Fuel Tank Pressure Sensor (10% likelihood) — Out-of-spec sensor. Warranty replacement.
- Charcoal Canister (5% likelihood) — Only from overfilling. Warranty replacement.
Hybrid/PHEV Note
If your Tucson is the hybrid or plug-in hybrid, the gas engine runs intermittently. EVAP purge monitors only activate when the engine is running, so code detection and clearing takes more drive cycles. The PHEV model runs on electric power more frequently, making the EVAP monitor even slower to complete. Components are the same across all variants.
Industry-Leading Warranty
Your 2024 Tucson 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.
