P1167 HYUNDAI MeaningThe Lambda closed-loop control system is included in the engine’ s control system. The control system regulates the lambda upstream with the HO2S signal. Rich mixtures generate high concentrations of CO, H2, and HC. Lean mixtures generate the high concentrations of NOx, and free oxygen.
If the lambda controller reaches the maximum or minimum threshold, then feedback control is no longer possible and emissions will be increased. The ECM sets DTC P1167 if no proportional fuel adaptation occurs for a defined time after the lambda controller has reached its minimum or maximum threshold.
