Investigating P0441 on Your 2022 Nissan Altima
A P0441 code on your 2022 Nissan Altima means the ECM detected incorrect purge flow in the EVAP system. The Altima uses a 2.5L four-cylinder engine (the turbocharged VC-Turbo is optional on SR trim). P0441 targets the purge circuit — the PVCV (Purge Volume Control Valve) and vacuum lines routing fuel vapors from the canister to the engine.
How Nissan Tests Purge Flow
The ECM commands the PVCV open during driving and monitors the fuel tank pressure sensor. Nissan's system also uses an active leak detection pump for integrity testing. When purge flow deviates from calibration, P0441 sets.
Ranked Causes
- PVCV Failure (35% likelihood) — The Purge Volume Control Valve is the leading suspect. After 2–3 years, internal valve wear can begin. Part: $35–$80. Labor: $55–$115.
- Vacuum Line Issue (20% likelihood) — Cracked or disconnected hoses between the PVCV, canister, and intake. Repair: $12–$40. Labor: $30–$80.
- Canister Close Valve (CCV) (15% likelihood) — Nissan's vent-side valve. Affects pressure dynamics during purge monitoring. Part: $30–$85. Labor: $80–$165.
- Leak Detection Pump (10% likelihood) — Nissan's active testing pump. Malfunction affects system monitoring accuracy. Part: $55–$130. Labor: $70–$140.
- Fuel Tank Pressure Sensor (10% likelihood) — Inaccurate readings. Part: $35–$85. Labor: $55–$110.
- Charcoal Canister (5% likelihood) — Saturation from overfilling. Part: $110–$280. Labor: $85–$175.
- Wiring/Connector (5% likelihood) — Corroded PVCV connector.
VC-Turbo Note
If your Altima has the optional 2.0L VC-Turbo engine, the variable compression turbo generates more underhood heat, which can accelerate vacuum line and PVCV deterioration. The EVAP system design is the same between both engines.
Warranty Check
Your 2022 Altima may still be within Nissan's 3-year/36,000-mile basic warranty. The 5-year/60,000-mile powertrain warranty and 8-year/80,000-mile federal emissions warranty provide additional coverage. Check with your Nissan dealer.
CONSULT Diagnostics
Nissan's CONSULT diagnostic system provides full EVAP access — PVCV command, CCV command, leak detection pump activation, and live pressure data. A Nissan dealer or shop with CONSULT access can pinpoint the exact cause.
Repair Costs
PVCV: $90–$195. Vacuum lines: $42–$120. CCV: $110–$250. Leak detection pump: $125–$270. FTP sensor: $90–$195. Charcoal canister: $195–$455.
