P0142 Error on Kia
What it means and how to fix it
🚨 Fault Description (P0142)
When your Kia dashboard warns of a fault and the OBD reader throws the P0142 error, the engine control module indicates this breakdown:
"O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)"
Although this is a standardized OBD2 code, the symptoms and the location of the faulty sensor can vary depending on the exact model of your Kia (year, engine type, etc).
