Understanding P0441 on Your 2024 Nissan Pathfinder
A P0441 code on your 2024 Nissan Pathfinder indicates incorrect purge flow in the EVAP system. The Pathfinder uses a 3.5L V6 engine paired with a 9-speed automatic. P0441 targets the purge circuit — the PVCV (Purge Volume Control Valve) and vacuum lines routing fuel vapors from the charcoal canister to the engine.
What P0441 Means
The ECM commands the PVCV open during driving and monitors the fuel tank pressure sensor. Nissan's active leak detection pump tests system integrity. When purge flow doesn't match calibration, P0441 sets. On a current-model-year Pathfinder, this is fully covered under warranty.
Primary Suspects
- PVCV Defect (35% likelihood) — A factory-defective Purge Volume Control Valve. Warranty replacement.
- PCM Software Calibration (20% likelihood) — Purge flow monitoring refinement. Warranty reflash via CONSULT.
- Vacuum Line Assembly (20% likelihood) — A hose not fully seated during production. Warranty repair.
- Canister Close Valve (CCV) (10% likelihood) — Factory defect. Warranty replacement.
- Leak Detection Pump (10% likelihood) — Factory defect affecting testing accuracy. Warranty replacement.
- Fuel Tank Pressure Sensor (5% likelihood) — Out-of-spec sensor. Warranty replacement.
