O2 Sensors. P0155 and P0161
I need help with O2 sensors please.

I replaced the Bank 2 Sensor 1 bc I got a P0155 code from Autozone. The engine light was still on so I went back to Autozone...now it shows P0161. Ok, so I changed the B2S2 O2 sensor...

Still, the engine light is on. I've read on threads about heat and open circuits... not sure what any of that means and what I can do. I'm getting frustrated and starting to feel it's not the O2 sensors that are bad.

Please help.

Thanks!

Go back to Parts store and use their OB II scanner to erase the code
