Drivers side, post turbo. You have to dig a bit to get to it, but with an offset O2 socket you can get it busted loose.

Codes

I got a P0036 code on my 09 Cobalt SS Coupe. All I find is it’s a HO2. So therefore I think okay, O2 sensor, crawl under the ar and only find one and it’s not hooked up just strapped up to the side. I found another sensor that seems the same(I haven’t pulled it yet cause too nervous lol) up by the turbo. But the thing that has me confused is it’s a 5 wire not a 4 as a usual o2 sensor would be?
also the car is running fine and air to fuel reads right and perfect and all. I’m so confused😡 I’ve tried resetting via battery and it just keeps coming back.
Please help!?
