Hello,

I need to replace o2 bank 1 sensor 2 because the engine code is p0136. I found 3 sensors but I'm not sure which one it is. Is the sensor the one that connects under the driver side seat after catalytic converter or is it located somewhere else? What is the spec for voltage and ohms because one sensor the one under the seat 13.5 when the car is cold and the other sensor in front of the engine which i think its bank 2 sensor 1, I get 1.5 ohms. Do you also know the OEM part number for the o2 sensor? Thank you

Thank you. Do you know the OEM part number for it? I found Denso 234-4215 but I am not sure if that is the OEM part number.
