P0057 KIA - How do I clear this code?

Question

i replaced the battery in a 2008 Kia Sorento, and this code can up. I replaced the sensor, but the code remains. If I clear the code, it comes back on the second engine start.

Answer 1

Hi there

This code means there is a problem with the heater circuit of the O2 sensor, bank 2 sensor 2. Typically the element inside the O2 sensor burns out and causes the problem. I would also check the wiring to the sensor to be sure it's not damaged.
