Investigating P0441 on Your 2021 Hyundai Palisade
A P0441 code on your 2021 Hyundai Palisade signals incorrect purge flow in the EVAP system. The Palisade uses a 3.8L V6 engine producing 291 hp. P0441 targets the purge circuit — the PCSV (Purge Control Solenoid Valve) and vacuum lines routing fuel vapors from the charcoal canister to the engine intake.
How the Code Sets
The ECM opens the PCSV during driving and monitors fuel tank pressure. When flow deviates from calibration, P0441 stores. After 3–4 years, early component issues are possible.
Ranked Causes
- PCSV Failure (35% likelihood) — The primary suspect. The 3.8L V6 generates moderate heat. Part: $30–$80. Labor: $55–$120.
- Vacuum Line Issue (20% likelihood) — Cracked or loose hoses from heat and vibration. Repair: $12–$40. Labor: $30–$85.
- Canister Close Valve (CCV) (15% likelihood) — Vent valve affecting pressure dynamics. Part: $30–$85. Labor: $80–$170.
- Fuel Tank Pressure Sensor (10% likelihood) — Inaccurate readings. Part: $35–$85. Labor: $55–$110.
- Charcoal Canister (10% likelihood) — From overfilling. The Palisade's larger tank means more vapor volume. Part: $100–$270. Labor: $80–$170.
- Wiring/Connector (5% likelihood) — Corroded connector.
- Gas Cap Seal (5% likelihood) — Check seal integrity. Replace: $8–$15.
