Investigating P0441 in Your 2022 Infiniti QX60
Your 2022 Infiniti QX60 — the all-new fourth generation sharing its platform with the Nissan Pathfinder, powered by the 3.5-liter V6 (295 hp) with a 9-speed automatic transmission — has triggered P0441 for incorrect EVAP purge flow. As a first-year redesign, the 2022 QX60 uses Nissan-derived EVAP architecture with Infiniti-specific calibrations. P0441 means the ECM detected abnormal fuel vapor purge flow during its periodic self-test.
Symptoms You Might Notice
- Steady check engine light
- Normal 3.5L V6 power (295 hp)
- AWD (if equipped) operating normally
- Possible fuel odor near the rear
- Emissions test failure
Common Causes — Ranked
1. Purge Volume Control Valve (PVCV)
Nissan/Infiniti calls the purge solenoid a "Purge Volume Control Valve." On the QX60's 3.5L V6, the PVCV controls vapor flow from the charcoal canister to the intake manifold. As a first-year model on a new platform, early-life PVCV issues can occur from manufacturing variability.
2. ECM Software Calibration
First-year 2022 QX60 models may have initial EVAP monitoring calibrations that need refinement. Nissan/Infiniti regularly releases TSBs for new platforms. An ECM update could resolve overly sensitive P0441 triggers.
3. Canister Vent Control Valve
The vent control valve seals the EVAP system during self-tests. On Nissan/Infiniti vehicles, this component is located near the charcoal canister and is exposed to road conditions.
4. Leak Detection Pump
Nissan/Infiniti uses a unique leak detection pump system to test EVAP integrity. A malfunctioning pump can cause false P0441 readings during self-tests.
5. Gas Cap Seal
The QX60 uses a traditional gas cap. The O-ring seal can deteriorate from fuel vapors and temperature cycling.
Diagnostic Steps
- Check gas cap — tighten or replace ($20–$40)
- Scan with CONSULT (dealer) or compatible OBD-II scanner for codes and freeze frame
- Test PVCV actuation
- Test canister vent control valve
- Check leak detection pump function
- Smoke test the EVAP system
Repair Cost Breakdown
- Purge Volume Control Valve: $130 – $290
- ECM software update: $0 – $160
- Canister vent control valve: $120 – $270
- Leak detection pump: $200 – $380
- Gas cap: $20 – $40
Can I Drive With P0441?
Yes. Your QX60's V6, 9-speed transmission, AWD, and all luxury features work normally. P0441 is emissions-only.
DIY vs Professional
Your 2022 QX60 should be within Infiniti's 4-year/60,000-mile basic warranty. Dealer service is the no-cost option. As a first-year redesign, the dealer may have specific TSBs for EVAP calibration. CONSULT diagnostics are needed for Nissan/Infiniti-specific testing. Federal emissions warranty (8 years/80,000 miles) provides extended coverage.
