Understanding P0441 on Your 2024 Kia Carnival
A P0441 code on your 2024 Kia Carnival indicates incorrect purge flow in the EVAP system. The Carnival uses a 3.5L V6 engine. P0441 targets the purge circuit — the PCSV (Purge Control Solenoid Valve) and vacuum lines routing fuel vapors from the canister to the engine. On a current-model-year vehicle, this is fully covered under warranty.
What P0441 Means
The ECM commands the PCSV open during driving and monitors fuel tank pressure. When flow doesn't match calibration, P0441 sets.
Primary Suspects
- PCSV Defect (35% likelihood) — Factory-defective purge valve. Warranty replacement.
- ECM Software Calibration (20% likelihood) — Purge flow monitoring refinement. Warranty reflash via KDS.
- 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.
Warranty Coverage
Your 2024 Carnival is covered by Kia's 5-year/60,000-mile basic warranty and 10-year/100,000-mile powertrain warranty (original owner). All repairs are free at any Kia dealer.
Service Visit
The technician uses KDS to check TSBs, command the PCSV, monitor pressure, and run diagnostics. Most P0441 repairs take 1–2 hours.
