Understanding P0441 on Your 2023 Hyundai Palisade
A P0441 code on your 2023 Hyundai Palisade indicates 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.
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 relatively new Palisade, this typically indicates a component defect or software calibration issue.
Primary Suspects
- PCSV Defect (35% likelihood) — A defective Purge Control Solenoid Valve. Warranty replacement.
- Vacuum Line Issue (20% likelihood) — A loosened or defective hose. Warranty repair.
- ECM Software (15% likelihood) — Purge flow calibration refinement. Warranty reflash via GDS.
- Canister Close Valve (CCV) (10% likelihood) — Vent valve defect. Warranty replacement.
- Fuel Tank Pressure Sensor (10% likelihood) — Out-of-spec. Warranty replacement.
- Charcoal Canister (5% likelihood) — Only from overfilling. Warranty replacement.
- Gas Cap Seal (5% likelihood) — Check seal. Warranty replacement if defective.
