Question

I got the engine code P0156 on my Hyundai, HO2S Circuit Bank 2 Sensor 2 where is it

Answer 1

HI there,

The heater circuit is part of the O2 sensor. This code is for bank 2 sensor 2 which is the sensor AFTER the catalytic converter. Without knowing the model or engine size I can't tell you which side of the engine, but the side with cylinder #1 is always bank 1.

Answer 2

P0156 HYUNDAI - HO2S Circuit Bank 2 Sensor 2
