SES Light P0154 My passenger side O2 sensor is giving me an SES light P0154 - O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 1). I entended the wires so they would fit with my longtubes. I checked all the connections and there were two loose wires that i fixed but my SES light is still on with P0154. I was looking on ac Delcos site and the correct O2 sensor for the right side is AFS-123. I have no cats and delted my rear O2 sensors so I was wondering if i can use the Post cat O2 sensor on the left side in place of the Pre cat one that is already there. On the web site they appear to be the same exact thing. Is this correct? Thanks

That is absolutely correct. If for whatever reason it doesn't work, you can always just buy one then. I'd try it before you spend more money. I have use my rears before in place, and can vouch that it works, but I have had them go bad and have replace both since then.
