Understanding P0441 on Your 2024 Nissan Sentra
A P0441 code on your 2024 Nissan Sentra indicates incorrect purge flow in the EVAP system. The Sentra uses a 2.0L naturally aspirated four-cylinder engine. P0441 targets the purge circuit — the PVCV (Purge Volume Control Valve) and vacuum lines routing fuel vapors from the charcoal canister to the engine intake.
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 Sentra, 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 connected during production. Warranty repair.
- Canister Close Valve (CCV) (10% likelihood) — Factory defect. Warranty replacement.
- Leak Detection Pump (10% likelihood) — Factory defect affecting system testing. Warranty replacement.
- Fuel Tank Pressure Sensor (5% likelihood) — Out-of-spec sensor. Warranty replacement.
Naturally Aspirated Advantage
The Sentra's 2.0L engine is naturally aspirated (no turbo), generating less underhood heat than the turbocharged engines in the Rogue and Altima. This means vacuum lines and the PVCV experience less heat stress, but factory defects can still occur.
Nissan Warranty Coverage
Your 2024 Sentra is covered by Nissan's 3-year/36,000-mile basic warranty and 5-year/60,000-mile powertrain warranty. All EVAP components are covered. All repairs are free at any Nissan dealer.
Service Visit
The technician uses CONSULT to check for TSBs, command the PVCV and CCV, activate the leak detection pump, and monitor pressure data. Most P0441 repairs take 1–2 hours.
