Understanding P0441 on Your 2024 Hyundai Kona
A P0441 code on your 2024 Hyundai Kona indicates incorrect purge flow in the EVAP system. The all-new 2nd-generation Kona offers a 2.0L four-cylinder (standard) or is available as an EV. P0441 applies only to the gasoline model 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 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
- PCSV 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 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.
New Platform
The 2024 Kona is a complete redesign with a new platform and significantly larger dimensions. First-model-year software calibration updates are common. Your dealer's GDS checks for TSBs automatically.
