Investigating P0442 on Your 2022 Kia Sportage
A P0442 code on your 2022 Kia Sportage 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 Sportage is the first year of the redesigned fifth generation on the N3 platform, available with a 2.5L four-cylinder, 1.6T hybrid, or 1.6T PHEV. Kia's EVAP system uses the PCSV, CCV, and FTPS. As a first-year redesign, some codes may relate to calibration.
