Understanding P0441 on Your 2024 Nissan Altima
A P0441 code on your 2024 Nissan Altima indicates incorrect purge flow in the EVAP system. The Altima uses a 2.5L four-cylinder engine. P0441 targets the purge circuit — specifically the Purge Volume Control Valve (PVCV) and vacuum lines that route fuel vapors from the charcoal canister to the engine intake for combustion.
What P0441 Means
The ECM commands the PVCV open during specific driving conditions and monitors the fuel tank pressure sensor for expected response. Nissan's EVAP system also uses an active leak detection pump to verify system integrity. When purge flow doesn't match calibration, P0441 sets. On a current-model-year Altima, this is fully covered under warranty.
Primary Suspects
- PVCV Defect (35% likelihood) — A factory-defective Purge Volume Control Valve. Nissan's term for the purge 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) — Nissan's vent-side valve. Factory defect affecting pressure dynamics. Warranty replacement.
- Leak Detection Pump (10% likelihood) — Nissan uses an active pump to test EVAP integrity. A faulty pump affects monitoring accuracy. Warranty replacement.
- Fuel Tank Pressure Sensor (5% likelihood) — Out-of-spec sensor. Warranty replacement.
Nissan EVAP Terminology
Nissan uses different names than other manufacturers: the purge valve is the PVCV (Purge Volume Control Valve), the vent valve is the CCV (Canister Close Valve), and the system uses an active leak detection pump rather than passive monitoring.
Nissan Warranty Coverage
Your 2024 Altima 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. Federal emissions warranty extends specific parts to 8 years/80,000 miles. All repairs are free at any Nissan dealer.
Service Visit
The technician uses CONSULT to check for TSBs, command the PVCV, monitor fuel tank pressure, and run EVAP diagnostics including the leak detection pump test. Most P0441 repairs take 1–2 hours.
