Tracking Down P0441 in Your 2024 Infiniti QX60
Your 2024 Infiniti QX60 — continuing on the Pathfinder-based platform with the 3.5-liter V6 (295 hp) and 9-speed automatic — has triggered P0441 for incorrect EVAP purge flow. As a nearly new luxury three-row SUV, warranty coverage is your primary path. P0441 means the ECM detected abnormal fuel vapor purge flow during its periodic self-test.
Symptoms You Might Notice
- Steady check engine light
- Normal V6 performance
- AWD (if equipped) working properly
- Possible fuel odor
- Emissions test failure
Common Causes — Ranked
1. ECM Software Calibration
On a 2024 QX60, software refinement is a leading suspect. As the platform matures from its 2022 launch, Nissan/Infiniti continues to update EVAP monitoring parameters. A dealer ECM reflash may resolve P0441.
2. Purge Volume Control Valve (PVCV)
The PVCV manages vapor flow from the charcoal canister to the V6's intake manifold. Manufacturing variability or early-life failure can cause abnormal purge flow readings.
3. Canister Vent Control Valve
The vent control valve near the charcoal canister can be affected by road conditions. It seals the EVAP system during integrity self-tests.
4. Leak Detection Pump
The Nissan/Infiniti leak detection pump tests EVAP system integrity. A marginally performing pump from the factory can trigger intermittent P0441 codes.
Diagnostic Steps
- Check gas cap seal
- Take to Infiniti dealer for CONSULT diagnostic scan
- Check for ECM updates and TSBs
- Component testing if software doesn't resolve
Repair Cost Breakdown
- All repairs: $0 under warranty
- PVCV (retail): $130 – $290
- Vent control valve (retail): $120 – $270
- Leak detection pump (retail): $200 – $380
Can I Drive With P0441?
Yes. Your QX60's V6, AWD, and all luxury features work normally.
Warranty Coverage
Your 2024 QX60 is within Infiniti's 4-year/60,000-mile basic warranty and 6-year/70,000-mile powertrain warranty. Schedule a dealer appointment — this should be a no-cost repair. Federal emissions warranty (8 years/80,000 miles) provides additional long-term EVAP protection.
