Understanding P0441 on Your 2023 Kia Telluride
A P0441 code on your 2023 Kia Telluride indicates incorrect purge flow in the EVAP system. The Telluride uses a 3.8L V6 producing 291 hp. P0441 targets the purge circuit — the PCSV 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 relatively new Telluride, this typically indicates a component defect or calibration issue.
Primary Suspects
- PCSV Defect (35% likelihood) — Defective purge valve. Warranty replacement.
- Vacuum Line Issue (20% likelihood) — Loose or defective hose. Warranty repair.
- ECM Software (15% likelihood) — Calibration refinement. Warranty reflash via KDS.
- 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.
