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 monitors front HO2S signal level during fuel cut-off to check plausibility. The ECM/PCM sets DTC P229700 if front HO2S signal is out of the predetermined threshold. If the same error code is set in the next driving cycle, the ECM/PCM illuminates the MIL.
