Understanding P0441 on Your 2023 Nissan Murano
A P0441 code on your 2023 Nissan Murano indicates incorrect purge flow in the EVAP system. The Murano uses a 3.5L VQ35DE V6 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.
What P0441 Means
The ECM opens the PVCV during driving and monitors fuel tank pressure. Nissan's active leak detection pump tests system integrity. When flow doesn't match calibration, P0441 sets. On a relatively new Murano, this typically indicates a component defect or software calibration issue.
Primary Suspects
- PVCV Defect (35% likelihood) — A defective Purge Volume Control Valve. Warranty replacement.
- Vacuum Line Issue (20% likelihood) — A loosened or defective hose. Warranty repair.
- PCM Software (15% likelihood) — Purge flow calibration refinement. Warranty reflash via CONSULT.
- Canister Close Valve (CCV) (10% likelihood) — Defect on Nissan's vent valve. Warranty replacement.
- Leak Detection Pump (10% likelihood) — Pump defect affecting test accuracy. Warranty replacement.
- Fuel Tank Pressure Sensor (5% likelihood) — Out-of-spec sensor. Warranty replacement.
- Charcoal Canister (5% likelihood) — Only from fuel overfilling. Warranty replacement.
