P0442 on Your 2022 Hyundai Santa Fe
A P0442 code on your 2022 Hyundai Santa Fe means the engine control module has found 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 2022 Santa Fe is available with a 2.5L four-cylinder, 2.5L turbo, or 1.6T hybrid powertrain. Hyundai's EVAP system uses the PCSV, CCV, and FTPS. Note that the hybrid model has modified EVAP monitor timing due to intermittent engine operation.
Probable Causes
- Gas Cap Issue — A loose or worn gas cap is the most common trigger. Check and replace if needed ($10–$20).
- PCSV Problem — Engine heat, especially from the 2.5T, can begin to affect the Purge Control Solenoid Valve even after a couple years.
- CCV Concern — The Canister Close Valve can be affected by moisture exposure.
- Hybrid EVAP Monitor Timing — If you have the hybrid, EVAP tests run less frequently, which can make borderline leaks more likely to trigger a code.
- FTPS Drift — Minor Fuel Tank Pressure Sensor calibration issue.
