I currently have my check engine and VCS light on. I pulled the codes and got Bank 2 sensor 2 P0158 oxygen sensors and p2197 Oxygen sensor Bank 2 sensor 1.I have managed to find the 2 sensors on the engine but am unsure which is bank 1 and 2. One sensor is near the radiator and the other is near the firewall. Also is it possible for the one sensor to be bad and give to bad codes.
