DTC Description
WARNING: This page is about a different car, the 2021 Kia Seltos. However, it is still accessible from the selected car via links, so may be relevant.
The ECM/PCM measures pressure in the fuel tank by means of tank pressure sensor during all engine operating states except engine stop and start. ECM/PCM sets DTC P242200 if the ECM/PCM detects that the fuel tank pressure is too low as a result of the stuck closed CCV.
