Tracking Down P0442 on Your 2022 Dodge Charger
A P0442 code on your 2022 Dodge Charger means the PCM detected a small leak in the evaporative emission system. After two to three years of service, the Charger's EVAP system may show early signs of wear — but the cause is usually something minor.
EVAP System Overview
The 2022 Charger uses Stellantis's NVLD (Natural Vacuum Leak Detection) system across all engine options — the 3.6L Pentastar V6, 5.7L HEMI V8, and 6.4L HEMI V8. The NVLD monitors system integrity through vacuum changes rather than an electric vent solenoid. The system also includes a purge solenoid and charcoal canister connected by vapor lines.
Most Likely Causes
- Gas cap seal issue (40%) — The most common trigger. After two to three years, the gasket can develop minor wear or pick up debris.
- EVAP hose connection looseness (25%) — Vapor line connections can loosen from road vibration, especially on the Charger's performance-oriented suspension.
- NVLD device issue (15%) — The NVLD can develop early faults, though this is less common at this vehicle age.
- Charcoal canister damage (10%) — Road debris impact on the underbody canister.
- Purge solenoid seal (10%) — Early seal degradation in the purge solenoid.
Diagnostic Steps
Inspect and replace the gas cap if worn. If the code persists, a Dodge dealer with wiTECH can run targeted NVLD and EVAP system diagnostics. A smoke test provides visual confirmation of the leak source. At this vehicle age, warranty coverage should handle the repair.
