P0442 on Your 2024 Hyundai Santa Fe Explained
The P0442 code on your 2024 Hyundai Santa Fe indicates the engine control module has detected a small leak in the evaporative emission control system. This system captures fuel vapors and recycles them through the engine. P0442 flags a leak roughly 0.020 inches in diameter.
The 2024 Santa Fe is a completely redesigned model with a bold new design, featuring a 2.5L turbocharged four-cylinder engine and available hybrid powertrain. As a first-year redesign, some P0442 codes may relate to software calibration rather than physical failures. Hyundai's EVAP system uses the PCSV, CCV, and FTPS.
Possible Causes
- Gas Cap Issue — A loose or cross-threaded cap. Check before visiting the dealer.
- New-Platform Software Calibration — The redesigned Santa Fe's EVAP monitoring may need calibration updates. Hyundai releases updates for new platforms regularly.
- PCSV Defect — A factory-defective Purge Control Solenoid Valve.
- CCV Issue — A manufacturing defect in the Canister Close Valve.
- FTPS Calibration — Sensor calibration refinement needed on the new platform.
Warranty-First Approach
- Check the gas cap — Free step that may resolve the code.
- Visit your Hyundai dealer — The 5-year/60,000-mile basic warranty and 8-year/80,000-mile federal emissions warranty cover all P0442 work. Zero cost.
- Ask about TSBs — Particularly important on a first-year redesign.
All work should be at no cost under Hyundai's generous warranty.
