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 fuel cut-off to check plausibility. The PCM sets DTC P2297-00 if front HO2S signal is out of the predetermined threshold. If the same error code is set in the next driving cycle, the PCM illuminates the MIL.
