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.

If the Lambda Controller reaches the maximum or minimum threshold, then feedback control is no longer possible and emissions will be increased. The PCM sets DTC P2191-00 if no proportional post catalyst fuel trim adaptation occurs for a defined time after the Lambda Controller has reached its maximum threshold at part load.
