P0442 on Your 2024 Kia Sorento Explained
The P0442 code on your 2024 Kia Sorento indicates the engine control module has detected a small leak in the evaporative emission control system. P0442 flags a leak roughly 0.020 inches in diameter.
The 2024 Sorento is available with a 2.5L four-cylinder, 2.5L turbo, 1.6T hybrid, or 1.6T plug-in hybrid. Kia's EVAP system uses the PCSV, CCV, and FTPS. Hybrid and PHEV models have modified EVAP monitor timing. As a current model year, full warranty coverage applies.
Possible Causes

- PCSV Defect — Factory-defective Purge Control Solenoid Valve.
- CCV Issue — Canister Close Valve manufacturing defect.
- FTPS Calibration — Sensor calibration refinement.
