DTC Description
WARNING: This page is about a different car, the 2021 Kia Soul. However, it is still accessible from the selected car via links, so may be relevant.
The purpose of this diagnosis is to monitor the minimum coolant temperature that enables lambda closed loop control after start. Minimum coolant temperature to run lambda control must be reached before the threshold time pre-determined according to intake air temperature at start. If the lambda control is not active because of low engine coolant temperature within pre-determined minimum time after start, the PCM sets DTC P012500.
