Investigating P0441 on Your 2020 Nissan Murano
A P0441 code on your 2020 Nissan Murano indicates incorrect purge flow in the EVAP system. The Murano uses a 3.5L VQ35DE V6 paired with a CVT. P0441 targets the purge circuit — the PVCV (Purge Volume Control Valve) and vacuum lines routing fuel vapors from the charcoal canister to the engine.
How Nissan Monitors Purge Flow
The ECM commands the PVCV open during driving and monitors fuel tank pressure. Nissan's active leak detection pump also tests system integrity. When measured flow deviates from calibration, P0441 stores. After 4+ years, component wear is the primary concern.
Ranked Suspects
- PVCV Failure (35% likelihood) — The leading suspect. The VQ35DE V6 generates significant heat that accelerates purge valve wear. Part: $35–$85. Labor: $55–$120.
- Vacuum Line Issue (20% likelihood) — Heat from the V6 degrades rubber hoses. Repair: $12–$40. Labor: $30–$85.
- Canister Close Valve (CCV) (15% likelihood) — Age-related wear on Nissan's vent valve. Part: $30–$85. Labor: $80–$170.
- Leak Detection Pump (10% likelihood) — Years of cycling wear the pump. Part: $55–$130. Labor: $70–$140.
- Charcoal Canister (10% likelihood) — Saturation from fuel overfilling. Part: $110–$280. Labor: $85–$175.
- Fuel Tank Pressure Sensor (5% likelihood) — Age-related drift. Part: $35–$85. Labor: $55–$110.
- Wiring/Connector (5% likelihood) — Corrosion from underbody moisture.
Warranty & Emissions
Nissan's 3-year/36,000-mile warranty has expired. The 5-year/60,000-mile powertrain warranty may still apply. The federal emissions warranty (8 years/80,000 miles) covers specific EVAP components through approximately 2028. Check with your dealer.
DIY Repair
The PVCV is accessible in the engine bay on the VQ35DE. Moderate DIY difficulty. A basic OBD-II scanner reads codes, but CONSULT provides full actuator testing for accurate diagnosis.
Repair Costs
PVCV: $90–$205. Vacuum lines: $42–$125. CCV: $110–$255. Leak detection pump: $125–$270. Charcoal canister: $195–$455.
