Investigating P0442 on Your 2022 Kia Sorento
A P0442 code on your 2022 Kia Sorento means the engine control module has found a small leak in the evaporative emission control system. P0442 flags a leak roughly 0.020 inches in diameter.
The 2022 Sorento is the second year of the current generation, available with a 2.5L four-cylinder, 2.5L turbo, 1.6T hybrid, or 1.6T PHEV. Kia's EVAP system uses the PCSV, CCV, and FTPS. After a couple years, minor component wear is possible.
Probable Causes
- Gas Cap Seal Issue — Loose or worn gas cap. Check and replace if needed ($10–$20).
- PCSV Problem — The turbo engine variants generate more heat that stresses the Purge Control Solenoid Valve.
- CCV Concern — Moisture and road debris can affect the Canister Close Valve.
- Hybrid EVAP Sensitivity — Hybrid models have EVAP monitors that run less frequently, making borderline leaks more likely to trigger a code.
- FTPS Drift — Minor Fuel Tank Pressure Sensor drift.
