I'm trying to learn this stuff lol. Im having problem's getting the graph to look like your pictures. I'm not sure what I'm doing wrong here. This is what mine looks like. I'm not sure how you got it to say scope on your ? I'm trying this without being connected I'm not sure if that's why ? Thank you for being so patient with me George. If it's possible to just do one thing at a time that would be much easier for me. I'm learning slowly my apologies.

No problem, we can go at whatever pace you want. Thats a good O2 sensor right there. Now lets look at B2S1 at idle and 2500. Then see if you get the same wonky ECT behavior in Torque.
Thanks George. I'll get the reading tomorrow and post it. If I can get torque to work I'll see what the ECT reading is. Torque lite won't connect for me for some reason.

So I know there is a 3rd O2 sensor. I'm pretty sure it called B1S3 I'm just not sure how to test that one because there is no option to pick it from the list. I see a B1S3 in the generic list. I guess I could try that one and see if it works. I'll let u know tomorrow if it does.

I see one option for B1S3 in the list of generic but it's listed as B1S3 % and when I select it the graph values on the left hand side and completely different. So I'm not sure what I can do to test the last O2 sensor ?

You have B1S1 and B2S1 as your pre-catalytic converter O2 sensors (two Banks, right and left). The third, a post-catalytic converter O2 sensor is B1S2. B=bank# S=sensor#
What year is your Blazer?
George, I'm not trying to take over. Just making sure he is not trying to use Car Gauge Pro or Car Diagnostic Pro on a 1996 or 1997 Blazer. It doesn't work for the Enhanced GM PIDs for those two years with the older PCM. However it does work for the SAE Generic PIDs. I don't see where he stated his year.
