My service engine light came on and after checking the code it said it was P0152, the #1 O2 sensor in Bank 2. So I replaced that with a Motorcraft sensor, reset the computer, and the Service light came on again. So I checked the code, and now I'm getting P0156, #2 O2 sensor in Bank 2. I have a feeling that maybe it's not the sensors, but could be an electrical problem somewhere. I'd like to think that it was an easy fix, and replacing the sensor would cure everything. But before I go out and buy another sensor, are there any other problems that could be causing this? I kind of have to question the fact that both sensors in Bank 2 would go out at the same time, but I guess you never know. The car's about to turn over 60k miles. Any help would be appreciated. Thanks.
Keep getting new PCM codes...help

An OR H or X pipe would cause that code to be thrown I believe, I am about to install a BBK OR X soon and have researched the codes being thrown so I know JIK something else where to happen to my car after the install...
I also think that a leak will throw that as well, but you should be able to narrow that down either soundwise or visually....

i was gonna guess an O/R pipe by the code. i would just get the car tuned and turn the rear o2's off rather trhan keep buying new ones. they are useless anyways
Everything's stock on the car. It had a drop-in K&N but I took it back out because it seemed like the codes started after it was put in. The car drives fine except after it's been running a while and I pull up to a light it idle is a little off. I put in new (Motorcraft) plugs but it's still the same. So my next day off I'm going to check all the wiring to the O2's. I already pulled, if I remember right, the #2 and 8 fuses. Not sure if that's relevent to my problem but they were fine. Anywhere else I should be checking? Thanks for the help so far.
check your 02 wiring, those are both circuit fault codes. Also check to see if the sensors got damaged somehow..
