DTC Description
WARNING: This page is about a different car, the 2021 Kia Soul. However, it is still accessible from the selected car via links, so may be relevant.
The ECM monitors front HO2S signal level during part load or full load operation to check if the front HO2S is mechanically attached to the exhaust gas pipe while the vehicle is running. The ECM sets DTC P241400 if front HO2S signal is within the predetermined threshold. If the same error code is set in the next driving cycle, the ECM illuminates the MIL.
