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 the Heated Oxygen Sensor (HO2S) transition frequency for predetermined time. During the monitoring period, the PCM calculates transition times that the front HO2S switches from rich to lean and from lean to rich. With this information, an average frequency for all switches can be determined. The PCM sets DTC P013300 when the average frequency is too slow.
