DTC Description
WARNING: This page is about a different car, the 2021 Hyundai Kona. However, it is still accessible from the selected car via links, so may be relevant.
The PCM monitors front HO2S signal level during partial or full load operation to check if front HO2S is properly installed to the exhaust gas pipe while the vehicle is running. The PCM sets DTC P2414-00 if front HO2S signal is within the pre-determined threshold. If the same error code is set in the next driving cycle, the PCM illuminates the MIL.
