Tracking Down P0442 on Your 2022 Dodge Durango
A P0442 code on your 2022 Dodge Durango indicates a small evaporative emission system leak. After two to three years of service, the cause is usually something minor — and your warranty should have you covered.
EVAP System Details
The 2022 Durango uses Stellantis's NVLD system across all engine options — the 3.6L Pentastar V6 and 5.7L HEMI V8. The NVLD monitors system integrity through vacuum changes rather than an electric vent solenoid. The three-row SUV's large fuel tank means extensive vapor line routing along the underbody.
Most Likely Causes
- Gas cap seal issue (40%) — The most common P0442 trigger. Check for wear, debris, or incomplete seating.
- EVAP hose connection looseness (25%) — The Durango's extensive vapor routing provides multiple connection points that can loosen from vibration.
- NVLD device issue (15%) — Early failure of the leak detection device, though uncommon at this age.
- Charcoal canister damage (10%) — Road debris impact on the underbody canister, more common on towing-duty Durangos.
- Purge solenoid seal (10%) — Early internal seal degradation.
Diagnostic Approach
Replace the gas cap if worn. If the code persists, your Dodge dealer can run wiTECH NVLD-specific diagnostics. A smoke test pinpoints the exact leak location. Warranty should cover all costs at this vehicle age.
