Just cruisin and threw a code... P0157
P0157 Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 2 Sensor 2
I'm guessing something happened to it, I haven't had time to actually look at the o2 sensor yet, but i just put an X pipe and headers on, anyone have any thoughts on what it could be? wiring? the actual sensor? thanks!

If I got this right thats the rear passenger side 02 sensor.
most people have the rear 02's deleted after a header install.
All of that suface area cools the exhaust quicker and causes a
slow reponse from the 02 sensor.
I would clear the code and run it a little and see if you get the same code again.

The tuner should help you out by turning the rear o2's off. You do want to make sure the wires do not come in contact with any exhaust parts. I installed some heat shielding on my disconnected rear o2 connectors.
I like to verify that all wires are tied up away from the pipes a week or so after any work in that area is done.

I had this code (both sides actually) with a very mild vacumn leak in the intake between the MAF sensor and the air bridge.
It would set, and sometimes with the C/E/L as well. Usually happened after a full throttle acceleration from a higher gear to redline, or in a long coast in gear down a hill.
Cured the vacumn leak, and no codes since (or CEL).
Don't know if that's your problem, but if you've been working on the intake, you may want to check that.
