today my truck cut the check engine light on and when i checked it was this code. it says no circuit activity and is detected on bank 1 sensor 2, which one is that? trucks got 4 like what im assuming is normal, before and after on both sides

the frount 2 will adjust to the trucks air/fueling the rears are for emission. just a heads up.

Ok, so if I don't change it immediately since it's the back one it's not like it's gonna totally mess with it, like i can still drive it till I get the new one in right?

Yeah...just expect shitty mpg

The rears don't adjust the air fuel, the fronts do that. They are only for emissions. So you should be fine for a while.

I had that code recently it turned out to be the wires had been pinched off on on the frame. Resoldered the connections and now I'm fine.

I would physically look at the sensor before replacing it. Mine was a denso. Prob want to put the same sensor back in. I Just slid under the truck and looked no need to jack it up.

Ok, well gas mileage I, not worried about since I only drive like 10 mins to school, and yeah I'll check the wiring, we did the trans recently and had to take the exhaust off so maybe some wire got moved and did short, and my dad has a acdelco one but it's got the wide 4 pin plug that would connect to the front but the rear has the square 4 pin so could we cut the plugs and solder them on and it be ok? Or is there a real difference in front to rear in how they work for fuel/air or emissions
