Investigating P0441 on Your 2022 Nissan Titan
A P0441 code on your 2022 Nissan Titan signals 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 intake.
How the Code Sets
The ECM opens the PVCV during driving and monitors fuel tank pressure. Nissan's active leak detection pump also tests integrity. When flow deviates from calibration, P0441 stores. The Titan's large fuel tank creates significant vapor volume, making purge flow monitoring sensitive to component performance.
Ranked Causes
- PVCV Failure (35% likelihood) — The primary suspect. The powerful 5.6L V8 generates substantial underhood heat. Part: $35–$90. Labor: $60–$125.
- Vacuum Line Issue (20% likelihood) — V8 heat and truck vibration degrade hoses. The Titan's large engine bay has longer line runs. Repair: $12–$45. Labor: $30–$90.
- Canister Close Valve (CCV) (15% likelihood) — Located near the rear on the full-size truck frame. Exposed to road debris. Part: $30–$90. Labor: $85–$175.
- Leak Detection Pump (10% likelihood) — Pump malfunction affecting test accuracy. Part: $55–$135. Labor: $75–$150.
- Fuel Tank Pressure Sensor (10% likelihood) — Inaccurate readings. Part: $35–$90. Labor: $55–$115.
- Charcoal Canister (5% likelihood) — The large fuel tank means more vapor volume through the canister. Part: $115–$290. Labor: $90–$180.
- EVAP Line Damage (5% likelihood) — Full-size truck underbody exposure.
Full-Size Truck Factors
The Titan's body-on-frame design exposes EVAP components to road debris, water, and mud. The CCV and leak detection pump near the rear are particularly vulnerable. Long vapor line runs from engine to rear create more potential failure points.
Warranty Status
Your 2022 Titan may still be within Nissan's 3-year/36,000-mile warranty. The 5-year/60,000-mile powertrain warranty and 8-year/80,000-mile federal emissions warranty provide additional coverage.
Repair Costs
PVCV: $95–$215. Vacuum lines: $42–$135. CCV: $115–$265. Leak detection pump: $130–$285. Charcoal canister: $205–$470.
