Understanding P0441 on Your 2024 Nissan Titan
A P0441 code on your 2024 Nissan Titan indicates incorrect purge flow in the EVAP system. The Titan uses a 5.6L Endurance V8 producing 400 hp. P0441 targets the purge circuit — the PVCV (Purge Volume Control Valve) and vacuum lines routing fuel vapors from the charcoal canister to the engine. On a current-model-year vehicle, this is fully covered under warranty.
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 flow doesn't match calibration, P0441 sets.
Primary Suspects
- PVCV Defect (35% likelihood) — Factory-defective purge valve. Warranty replacement.
- PCM Software Calibration (20% likelihood) — Purge flow monitoring refinement for the V8. 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. Warranty replacement.
- Fuel Tank Pressure Sensor (5% likelihood) — Out-of-spec sensor. Warranty replacement.
