Investigating P0441 on Your 2019 Nissan Sentra
A P0441 code on your 2019 Nissan Sentra indicates incorrect purge flow in the EVAP system. The 2019 Sentra — the final year of the B17 generation — uses a 1.8L four-cylinder engine. P0441 targets the purge circuit — the PVCV (Purge Volume Control Valve) and vacuum lines routing fuel vapors from the canister to the engine.
How the Code Sets
The ECM commands the PVCV open during driving and monitors fuel tank pressure. Nissan's leak detection pump runs additional tests. When purge flow deviates from calibration, P0441 stores. After 5+ years of service, component wear is the primary concern.
Ranked Suspects
- PVCV Failure (35% likelihood) — The leading suspect. Five-plus years of operation degrades the internal valve. Part: $35–$75. Labor: $50–$105.
- Vacuum Line Deterioration (25% likelihood) — The 1.8L is naturally aspirated with moderate heat output, but years of thermal cycling still degrade rubber. Repair: $10–$35. Labor: $25–$70.
- Canister Close Valve (CCV) (15% likelihood) — Age-related wear on the vent valve. Part: $25–$80. Labor: $75–$155.
- Leak Detection Pump (10% likelihood) — Years of cycling wear out the pump. Part: $50–$120. Labor: $65–$135.
- Charcoal Canister (10% likelihood) — Saturation from years of overfilling. Part: $95–$250. Labor: $80–$160.
- Fuel Tank Pressure Sensor (5% likelihood) — Age-related drift. Part: $30–$80. Labor: $50–$100.
B17 Generation Notes
The 2019 is the last B17 Sentra. The 1.8L engine is a simpler, lower-output powerplant that generates less heat stress than newer turbo models. However, after 5+ years, all rubber and electronic EVAP components are subject to age-related degradation.
Warranty & Emissions
Nissan's basic and powertrain warranties have expired for most 2019 models. The federal emissions warranty (8 years/80,000 miles) may still cover specific components through approximately 2027. Check with your Nissan dealer.
DIY Repair
The PVCV on the 1.8L Sentra is accessible in the engine bay and is a straightforward replacement. The compact engine bay of the Sentra makes most underhood EVAP components easy to reach. A basic OBD-II scanner reads codes; CONSULT provides full actuator testing.
Repair Costs
PVCV: $85–$180. Vacuum lines: $35–$105. CCV: $100–$235. Leak detection pump: $115–$255. Charcoal canister: $175–$410.
