Hi everybody,

I'm new to the forum and currently I have a problem with P0051 - Oxygen Sensor Heater Control Circuit Low Bank 2 Sensor 1 code. My 2007 IS250 AWD has 53k miles so I don't know if it's possible for the sensor to go out or not. I tried to reset the code with the scanner and remove the battery but no work...

So now I plan to change the O2 sensor and wonder if the any step by step guide for that? Is it easy to DIY? And is the location for the sensor on the passenger side before the catalytic converter?

Thanks for all the help and time!
