Hows it going guy's and gals. Hoping you guys can help me with a bit of a situation i got with my 97 gmc yukon 5.7. Let me give you a bit of info on his truck. I recently put a brand new crate engine from gm. Had no problems even now. With this check engine code popping up. Got a code p0161 which is for bank 2 sensor 2. Even now, with this check engine code truck runs perfect.No issues. I was hoping you guys can help me read the scanner. The first picture is the code. The second 2 pictures. Are the freeze frames off when the system failed. But I don't know how to break down what is showing me. The last picture is a live feed the thing I noticed is the volts on bad 2 sensor 2 is low compared to the others. I've never changed my downstream o2 sensors only my upstream. And my cats are new. In the gm manual is says the last thing to do is change the sensor but the first thing to check is the voltage.kinda wanted to know if the scanner is telling me the sensor is bad by the low and high voltage
